HMC980LP4E Description
The HMC980LP4E is an active bias controller that can automatically adjust the gate voltage of an external amplifier to achieve a constant drain current. Using an integrated controller, the HMC980LP4E allows safe power-up/power-down, and disables/enables of an external amplifier, ensuring the safe powering of the amplifier. The HMC980LP4E can be used to bias any enhancement or depletion type Class A amplifier operating with drain voltages from 5 V to 16.5 V and drain currents up to 1.6 A, thus offering a complete biasing solution.
