What Is the RF Connector_ RF Connector Classification and Specification Introduction
What Is the RF Connector_ RF Connector Classification and Specification Introduction
The RF connector is connected with coaxial cable, microstrip line or other RF transmission lines to realize the electrical connection, separation or transfer of different types of transmission lines. It belongs to mechatronics products and acts as a bridge.The model of RF coaxial connector consists of main name code and structure code, separated by short horizontal line "-". Main name code the main name code of RF connector adopts the international general main name code, and the naming of different structural forms of specific products shall be specified in the detailed specification. Structure type code: structure of RF connector.2 Classification of RF connectors1) According to the connection interface structure, it is divided into:Bayonet type (inner bayonet, outer bayonet): BNCThreaded type (right-hand thread, left-hand thread): L29 (7 / 16), N, F, TNC, SMA, SMC, SSMA, SSMB, FME, L9 (1.6 / 5.6), 7mm, 3.5mm, 2.4mm, K (2.92mm), 1.85mm, 1mm;Push in type (in-line, self-locking): SMB, SSMB, MCX, MMCX, SMP, SMI, BMA, SAA;Flanged:2) Classification by size:Standard type: UHF, N, 7 / 16, 7mm;Small: BNC, TNC;Subminiature: SMA, SMB, SMC, MCX, BMA, SAA, 3.5mm;Micro: SSMA, SSMB, MMCX, 2.4mm, K (2.92mm), 1.85mm, 1mm;3 Main specifications of RF connectorImpedance: almost all RF connectors and cables are standardized to an impedance of 50 . The only exception is generally 75 system, which is usually used for cable TV installation. It is also an important RF coaxial cable connector with matching cable characteristic impedance. If not, a discontinuity is introduced and loss may result.VSWR (voltage standing wave ratio): ideally, it should be unity. Good design and implementation can keep VSWR below 1.2 in the range of interest.Frequency range: now most RF work in the range of 1 to 10GHz, so the connector must have low loss in this area. For cases above 10GHz - there is a lot of work now in the 10 to 40GHz range - there are newer connectors to choose from. They are expensive because it is the cable itself.Insertion loss: This is the connector loss in the frequency range of interest. Losses are usually between 0.1 and 0.3 dB. Determining how critical per watt (or fractional Watt) is in most designs, even such a small loss must be minimized and included in the link loss budget. It is especially important when the signal strength and signal-to-noise ratio are low.Operating cycle: how many connection / disconnection cycles can be connected and withstand and still meet their specifications? This is usually in 500 or 1000 cycles. For threaded connectors, the tightening torque specified by the supplier is an important factor in maintaining performance and reliability.Power: power processing is determined by two resistance losses (heating) and insulation breakdown. Although even decades of design has been mainly pre-processing tens of watts, today's design community focuses on low-power devices, such as mobile phones, Pico cellular and millipico cellular base stations, video interfaces, RF and gadgets. These are in the sub 1W range, so the connector can be much smaller and its power rating is a smaller constraint.
How to Optimize the Transformer Design in Poe Power Supply
How to Optimize the Transformer Design in Poe Power Supply
Power over Ethernet - Ethernet power supply technology refers to a way in which power supply equipment PSE (power sourcing equipment) transmits power to power receiving equipment PD (power device) through network cable. Typical applications, for example, take the PSE switch as the core and connect many PD devices through network cables, such as access point, IP phone and IP camera. PSE completes the signal and power transmission to PD.Poe power supply has the following advantages: convenient installation and expansion: network cable transmits signal and power, and there is no need to configure power interface around PD equipment remote management: one PSE device provides power for multiple PD devices, which is convenient for remote power management low cost: signal line and power line are combined into one, eliminating one power line, so network cable is not only the carrier of signal transmission, It also plays the role of power transmission, so the wiring cost is reduced good compatibility: it is not limited by the power grid standards of various countries, and the unified Poe protocol ensures that PD equipment can be compatible with any PSE worldwideFrom the perspective of circuit architecture, the PSE on the left transmits DC 44-57v to PD, and the PD on the right cooperates with step-down circuit to convert the power supply into required power. PSE and PD are connected through RJ45 interface and up to 100m twisted pair.IEEE 802.3af, IEEE 802.3at andIeee802.3bt three Ethernet power supply standards. In particular, the IEEE 802.3bt standard was released in 2019, which greatly increased the power supplied by Poe. PSE provides 90W power. After passing through 100m network cable, the received power of PD reaches 71w. This class 8 power level is mainly used in the power supply system of small base stations. Moreover, 802.3bt standard is downward compatible with 802.3af and 802.3at standards; When the 802.3bt PD is connected to the low-power 802.3af and 802.3at PSE, it will work in the low-power state, that is, "degraded".In this process, the lower power PD is connected to the higher power PSE, and the equipment is not damaged. The following handshake process is mainly experienced when the PSE supplies power to the PD:Pictures from the InternetThe picture comes from the network, and the chart comes from the inside of shunluoIn the circuit architecture of PD equipment, three parameters are mainly concerned: size, efficiency and EMC. Then how to connect the requirements of PD equipment and the design requirements of transformer.//3.1 optimized size key points of design 1: reduce the size of the transformer with high frequency. In a circuit board, it can be seen that the larger the volume is the transformer, so reducing the size of the transformer can save the size of the board. High frequency can reduce the size of transformer and power transmission of transformer, so the frequency from 200 kHz to 300 kHz to 500 kHz can reduce the volume of transformer. Design point 2: CCM working mode reduces device size design point 3: primary side feedback reduces sizePictures from the Internet3.2 improving efficiencyEMC measures the interference of noise source on sensitive equipment, including conduction and radiation composition. On the one hand, reduce the interference source, on the other hand, optimize the coupling path.In order to reduce EMI, first confirm the noise source in the circuit. The noise source is divided into conduction noise source and radiation noise source. The conducted noise source is generally low-frequency noise within 30MHz, which is generated by the change of electric field; The conduction noise source is mainly the switching action of the power tube, which will lead to the sudden change of MOS source level voltage, which will lead to the transformer transmitting the sudden change of voltage to the secondary side. Increasing the driving resistance of MOS can reduce the switching speed, but the driving loss will increase; Or increase the absorption circuit to reduce the high-frequency oscillation. Stray parameters of transformer have a great impact on EMI. For example, transformer CP (primary winding electric field) affects voltage spike and current ripple.The radiated noise source is the noise above 30m, which is the interference of spatial magnetic field and consists of high-frequency current loop. High frequency loop refers to the primary side loop and secondary side loop of transformer. During PCB layout, the loop path should be reduced to reduce noise, or small capacitance in parallel should be added.3.3 shunluo electronic transformerShunluo electronics has a strong transformer design team. In the transformer design of Poe power supply, it comprehensively optimizes the transformer design from the perspective of size, efficiency and EMC to meet the customized needs of customers. Shunluo electronics has a fully automatic transformer production line to ensure the reliability and consistency of products and short delivery cycle. You are welcome to place an order.Editing: JQ

What Are the Reasons for the Damage of Silicone Rubber Cable
What Are the Reasons for the Damage of Silicone Rubber Cable
The main material of silicone rubber cable is silicone rubber. Due to its unique physical structure, it has unique physical properties, especially the unique and sufficiently advantageous performance of high temperature resistance. It can withstand high temperatures of more than minus 100 C and above zero 300 C, and its physical properties decline only a little, Its external stress and strain properties change little, and at high temperature, compared with other materials, the physical properties of silicone rubber cable decrease slightly, about 75% of the original performance, but other materials can't look directly at it, and the general materials will decrease to about 15%, This is the most difference between silicone rubber and other ordinary materials, which is high temperature resistance. Of course, it has many other physical properties.Silicone rubber cables are used for a certain period of time. After a certain period of time, the cable will have quality problems. At this time, it needs to be recycled and re laid. In addition to its own problems, external force is also a great factor causing the damage of silicone rubber cable. Therefore, our silicone rubber cable manufacturers should:When laying cables, areas with good geology shall be selected for laying. Laying cables in areas with high pH will seriously corrode the insulation of silicone rubber cables, resulting in great potential safety hazards.Be careful during construction. Some places such as joints need to be treated with care. In recent years, some accidents occurred because the joints were not fully connected due to the negligence of workers during construction, so that accidents occurred.In addition to laying cables outside the construction site, attention should be paid to the site selection for laying cables in the city. Someone asked, do buildings need to be selected, and do you also need site selection for laying silicone rubber cables? Yes, it's also important to choose a good address. If you choose an address and don't want to build a building on it in the future, isn't it very dangerous for your silicone rubber cable to be buried underground when you start the machine?Silicone rubber cables are not all right after laying. It is also necessary to arrange personnel of silicone rubber cable manufacturers to conduct regular inspection. Of course, they are not inspected every inch. Silicone rubber cables are buried underground. Check the operation of silicone rubber cable to see if there is any leakage. There is nothing missing as a whole. If any problem is found, it needs to be maintained and repaired in time.fqj
