A transmit/receive multifunctional module is a highly integrated RF module that integrates the transmit chain and receive chain into a single package. It typically includes power amplifiers, low-noise amplifiers, transmit/receive switches, limiters, phase shifters, attenuators, filters, and control circuits, enabling functions such as transmit/receive switching, transmit power amplification, receive low-noise amplification, amplitude/phase control, filtering, and limiter protection. The product features high integration, high transmit power, low noise figure, high isolation, fast switching speed, high amplitude/phase control accuracy, 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 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 transmit/receive multifunctional solutions according to customer needs.
