Product Description

Product Details
HMC980LP4E is an active bias controller that can automatically adjust the gate voltage of an external amplifier to achieve constant bias current. With an integrated controller, HMC980LP4E achieves safe power on/off, disable/enable and automatic supply sequencing ensuring the safety of the external amplifier. It can be used to bias any enhancement and depletion type amplifier operating in Class-A regime with Drain voltages (VDRAIN) from 5V to 16.5V and drain currents (IDRAIN) up to 1.6 A, offering a complete biasing solution.
HMC980LP4E 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 HMC980LP4E is housed in an RoHS compliant 4x4 mm QFN leadless package with an exposed backside pad to improve thermal characteristics.
Applications
Microwave Radio & VSAT
Military & Space
