A digitally controlled delay multifunctional module is a multifunctional RF module that integrates digitally controlled delay lines/delay devices with RF switches, amplifiers, attenuators, phase shifters, and control circuits into a single package. Through digital control signals, it sets the delay amount to provide precise and programmable signal delay, and can also implement functions such as channel switching, gain/amplitude adjustment, phase shifting, and signal routing. The product features a wide delay range, fine delay step, high delay accuracy, low insertion loss, good amplitude/phase consistency, fast switching speed, high integration, 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 digitally controlled delay multifunctional solutions according to customer needs.
