HMC980 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, HMC980 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.
HMC980 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.
