An amplitude and phase control multifunctional module is a highly integrated module that integrates amplitude/phase control functions and multiple RF functions into a single package. Through digital or analog control signals, it precisely adjusts the amplitude and phase of signals and can implement functions such as attenuation, phase shifting, amplification, switching, and limiting. It features high amplitude/phase control accuracy, wide dynamic range, good phase consistency, high integration, small size, light weight, and high reliability. The product 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 phased-array radar, communications, electronic countermeasures, satellite communications, test and measurement, and other fields. Based on MMIC and SiP technologies, the company can provide customized amplitude and phase control multifunctional solutions according to customer needs.
