What should I pay attention to if I install RF connectors on cables?

RF connectors (hereinafter referred to as RF connectors) are generally regarded as a component that is mounted on a cable or installed on an instrument as a coaxial cable protective grounding or detachable component. It is categorized as a mechatronics commodity. Simply put, it is the key to the highway bridge effect. Compared with other electronic components, RF connector development history is relatively short, UHF connector appeared in 1930 is the beginning of RF connector. Come to the period of World War II, because of the shortage of war, along with the development trend of radar detection, broadcasting and fiber optic communications, resulting in N, C, BNC, TNC, small and medium-sized series of products, after 1959, SMA, SMB, SMC and other miniaturized commodities, in 1964, the development of the British military industry with the specification of the MIL-C-39012 "General Specification for RF coaxial connectors", and since then, RF connectors just began to be used. Since then, RF connectors have just begun to standardization, generalization, practical orientation development trend. RF coaxial connector working standard voltage: 250V frequency range: 0-4gHz (50 Ohm) / 0-2GHz (75 Ohm) material resistance: 750V circuit resistance: inner conductor <6mOhm, outer conductor <1mOhm grounding resistance: >1000 megohm VSWR: <1.34 Raw materials: cover: purple copper plated with hard gold ductile touch rod: beryllium bronze plated with hard gold pin plugs : Purple copper hard gold-plated conductor and insulator: PTFE sleeve Sleeve: alloy copper nickel-plated or gold-plated 8.SMC specification: MIL-C-39012, IEC169-18, CECC22140 characteristics: small and medium-sized external threaded temperature range: -65 ~ +165 use performance: 500 times PLUG ID / JACK diameter: 3.8mm / 3.7mm Electrical Equipment Characteristics: Characteristic Impedance: 50 Ohm Operating Standard Voltage: 250V Frequency Range: 0-10GHz Substance Resistance: 750V Circuit Resistance: Inner Conductor <6mOhm, Outer Conductor <1mOhm Grounding Resistance: >1000 megohm VSWR: Straight <1.25 Copper Leg <1.35.
