A switch multifunctional module is a multifunctional RF module that integrates RF switches with attenuators, phase shifters, limiters, filters, amplifiers, and control circuits into a single package. Through control signals, it performs channel selection, transmit/receive switching, and signal routing, and can also integrate functions such as attenuation, phase shifting, limiting, filtering, and amplification. The product features low insertion loss, high isolation, fast switching speed, high amplitude/phase control accuracy, good consistency, small size, light weight, and high reliability. It can cover the DC–50 GHz microwave/millimeter-wave signal chain and meet the requirements of different quality grades of national military standards (GJB) and various application platform environments. It is widely used in radar, communications, electronic countermeasures, satellite communications, test and measurement, and other fields. Based on MMIC and SiP technologies, the company can provide customized switch multifunctional solutions according to customer needs.
