Functional Diagram
General Description
the HMC973LP3e is an absorptive Voltage Variable Attenuator (VVA) which operates from 0.5 to 6 GHz and is ideal in designs where an analog DC control signal must be used to control rF signal levels over a 26 dB amplitude range. It features a shunt-type attenuator controlled by an analog voltage, Vctrl. unlike other GaAs Fet based VVA’s the HMC973LP3e exhibits excellent linearity of +35 dBm input IP3, throughout it’s control range. the HMC973LP3e is an unidirectional device with optimum linearity performance achieved when the rF input signal is applied to the rFIn package lead. the HMC973LP3e is housed in a roHs compliant 3x3 mm QFn leadless package.

the circuit board used in the application should use rF circuit design techniques. signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. the evaluation circuit board shown is available from Hittite upon request.
