Download Datasheet Visit Manufacturer Site View Pricing & Stock

HMC981LP3E is an active bias controller that automatically 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 from 4V to 12V and drain currents up to 200mA, offering a complete biasing solution.HMC981LP3E achieves excellent bias stability over supply, temperature and process variations, and eliminates the required calibration procedures usually employed to prevent RF performance degradation due to such variations.The HMC981LP3E is housed in an RoHS compliant 3x3 mm QFN leadless package with an exposed backside pad to improve thermal characteristics.
