HMC980 Datasheet ACtive Bias Controller

Manufacturer: Hittite Microwave Corporation

Overview: Bias Controllers - Chip v00.0312 Typical Applications • Microwave Radio & VSAT • Military & Space • Test Instrumentation • Fiber Optic Modulator Driver Biasing • CATV Laser Driver Biasing • Cellular Base Station •.

General Description

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 plete biasing solution.

Key Features

  • Automatic Gate voltage adjustment (No Calibration required).
  • Supply Voltage (5V to 16.5V).
  • Bias both Enhancement or Depletion type devices.
  • Adjustable Drain Current up to 1.6 A.
  • Sink or source gate current.
  • Internal negative voltage generation.
  • Can be disabled to use external negative rail.
  • Fast Enable/Disable.
  • Trigger-out Output for Daisy Chain.
  • Power-Up and Power-Down Sequencing.
  • Over.
