A voltage-controlled attenuator amplifier module is a multifunctional RF module that integrates a voltage-controlled attenuator and an amplifier into a single package. It continuously adjusts the attenuation through an external control voltage to achieve precise control of signal amplitude, and can provide gain compensation or amplification for the attenuated signal. The product features wide dynamic range, high attenuation accuracy, good linearity, fast response, 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 voltage-controlled attenuation and amplification solutions according to customer needs.
