A digitally controlled attenuator amplifier module is a multifunctional RF module that integrates a digitally controlled attenuator and an amplifier into a single package. It sets the attenuation through digital control signals (such as serial, parallel, or TTL-compatible control signals) to achieve precise and programmable adjustment of signal amplitude, and can provide gain compensation or amplification for the attenuated signal. The product features fine attenuation step, high attenuation accuracy, wide dynamic range, good linearity, fast switching speed, good consistency, 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 digitally controlled attenuation and amplification solutions according to customer needs.
