I don't know how much you know about the main specifications of RF connectors, as an electronic components industry practitioners, buyers, it is necessary to understand some of the basic knowledge of RF connector specifications. In general, how are the main specifications of RF connectors evaluated?
Impedance: Almost all RF connectors and cables are standardized to a 50-ohm impedance. The only exception is generally that a 75-ohm system is typically used for cable TV installations. It is also important for RF coaxial cable connectors to have characteristic impedances that match the cables. If this is not the case, an discontinuity is introduced and loss may result.
VSWR (Voltage Resident Wave ratio): Ideally should be united, well designed and implemented to keep VSWR below 1.2 in the range of interest.
Frequency range: Most RF operations are now in the range of 1 to 10GHz, so the connector must have a low loss in this area. For cases above 10 GHz - where 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 it is the cable itself.
Insertion loss: This is the connector loss in the frequency range of interest. Losses are usually 0.1 and 0.3 decibels. Determined how critical per watt (or fractional watt) is in most designs, even such small losses must be minimized and included in the link loss budget. It is especially important at the low noise front end when the signal strength and signal-to-noise ratio are low.
Operating cycle: How many connection/disconnect cycles can be connected to withstand and still meet its specifications? This is usually in 500 or 1000 cycles. Threaded connectors, supplier-specified fastening torques are an important factor in maintaining performance and reliability.
Power: Power treatment is determined by two resistance losses (heating) and insulation breakdown. Although even decades of design have been designed primarily for pre-processing dozens of watts, today's design community focuses on low-power devices such as mobile phones, microcells and nanocell 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 smaller constraints.
