An RF front-end module (FEM) is a highly integrated multifunctional packaged product that integrates power amplifiers, low-noise amplifiers, RF switches, filters, attenuators, phase shifters, and control circuits into a single package. It performs functions such as power amplification of transmit signals, low-noise amplification of receive signals, transmit/receive switching, filtering, and amplitude/phase control. The product can cover the DC–50 GHz microwave/millimeter-wave signal chain and features small size, light weight, high integration, low insertion loss, high isolation, and high reliability. It meets the requirements of different quality grades of national military standards (GJB) and various application platform environments, and 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 RF front-end solutions according to customer needs.
