　　Impedance: almost all RF connectors and cables are standardized to 50 Ω. The only exception is that 75 Ω systems are commonly used in cable TV installations. It is also an important RF coaxial cable connector with matching cable characteristic impedance. If not, a discontinuity is introduced and the 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 10 GHz, so the connector must have low loss in this area. For cases above 10 GHz - there are a lot of things that work now in the 10 to 40 GHz range - there are newer connectors to choose from. They are expensive because of the cable itself.

　　Insertion loss: This is the loss of the connector in the frequency range of interest. The loss is usually between 0.1 and 0.3 dB. In most designs, even such a small loss must be minimized and included in the link loss budget. It is in the low noise front end, especially when the signal strength and SNR are low.

　　Operation cycle: how many connection / disconnection cycles can be sustained and still meet the specification? This is usually 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 handling is determined by two resistance losses (heating) and insulation breakdown. Although even decades of design have focused on pre-processing over tens of watts, today's design community focuses on low-power devices, such as mobile phones, picocells and femtocells, base stations, video interfaces, RF and gadgets. These are in the secondary 1W range, so the connector can be much smaller and its rated power is less constrained.

　　Yangzhou Hongbo Electronic Industry Co., Ltd. is located in Yangzhou, a famous economic development city in the Yangtze River Delta. It focuses on the production, sales, research and development of GATV, posts and telecommunications, radio communication and RF connectors. It is one of the more mature connector manufacturers in China. Products through the national supervision and inspection center inspection, quality first, is the cable manufacturers at home and abroad, connector fixed-point suppliers.
