Functional Diagram  
General Description  
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.
