HMC712ALP3CE

HMC712ALP3CE is an absorptive Voltage Variable Attenuator (VVA). It features two shunt-type attenuators which are controlled by two analogue voltages, Vctrl1 and Vctrl2. Optimum linearity performance of the attenuator is achieved by first varying Vctrl1 of the 1st attenuation stage from -5V to 0V with Vctrl2 fixed at -5V. Furthermore, if the Vctrl1 and Vctrl2 pins are connected together it is possible to achieve the full analogue attenuation range with only a small degradation in input IP3 performance. Applications include AGC circuits and temperature compensation of multiple gain stages in microwave point-to-point and VSAT radios. Typical application includes test instrumentation, microwave sensors, military, ECM & radar.
