General Description

HMC981 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.

HMC981 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.

All data shown herein is taken with appropriate probes.
