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.
