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.
