Part details & applications

The ADH812S is an absorptive Voltage Variable Attenuator (VVA) which operates from 5 GHz to 18 GHz and is ideal in designs where an analog DC control signal must be used to control RF signal levels over a 30 dB amplitude range. It features two shunt-type attenuators which are controlled by two analog voltages, Vctrl1 and Vctrl2. Optimum linearity performance of the attenuator is achieved by first varying Vctrl1 of the 1st attenuation stage from -3V to 0V with Vctrl2 fixed at -3V. The control voltage of the 2nd attenuation stage, Vctrl2, should then be varied from -3V to 0V, with Vctrl1 fixed at 0V. The ADH812S is housed in a 12-Lead ceramic hermetic leadless chip carrier package.

However, if the Vctrl1 and Vctrl2 pins are connected together, it is possible to achieve the full analog attenuation range with only a small degradation in input IP3 performance.
