What factors should be considered when choosing an RF connector
RF connector is a kind of connection device that can transmit RF signals with small loss and reflection in RF transmission system and provide fast and repeated connection. It is mainly composed of contacts, insulators, shells and accessories. The RF connector should be selected with reliable contact, good conductive insulation performance, sufficient mechanical strength, and the number of plug-ins to meet the relevant international and domestic standards. At the same time, there are many factors that determine the connector series and style, of which the mating cable and the use of frequency range are the main factors. In engineering practice, make the connector diameter and cable diameter as close as possible to minimize reflections. The greater the difference between cable diameter and connector diameter, the worse the performance. Reflections generally increase as a function of frequency, and generally smaller connectors perform well at higher frequencies. For very high frequencies (above 26GHz), sophisticated air media connectors are required.

Microwave transmitter is one of the important components of radar, communication and electronic countermeasure systems. Its main function is to provide high-power radio frequency signals that meet the requirements, convert low-frequency AC energy into high-power radio frequency energy, and radiate it into space through the antenna feed. The transmitter is composed of several parts of circuits such as a radio frequency system, a modulator, a power supply, a system monitoring and a cooling system, and the radio frequency system includes a radio frequency amplifier and radio frequency components. RF amplifiers include solid-state amplifiers, vacuum tube amplifiers, etc.
