HMC920LP5E
v07.1013
ACTIVE BIAS CONTROLLER
HMC920LP5E is an active bias controller which generates a regulated Drain voltage and actively adjusts the gate
voltage of an external amplifier to achieve constant bias current. It can be used to bias any enhancement and depletion
type amplifiers operating in Class-A regime with Drain voltages (VDRAIN) from 3V to 15V and drain currents (IDRAIN)
up to 500mA, offering a complete biasing solution.
HMC920LP5E achieves excellent bias stability over supply, temperature and process variations, and eliminates the
required calibration procedures used to prevent RF performance degradation due to such variations.
The HMC920LP5E is housed in an RoHS compliant 5x5 mm QFN leadless package with an exposed backside pad
to improve thermal characteristics.
