HMC980 Datasheet (Hittite Microwave Corporation)

HMC980, Active Bias Controller

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 amplifie
