HMC981 Datasheet ACtive Bias Controller

Manufacturer: Hittite Microwave Corporation

Overview: www.DataSheet.co.kr HMC981 v00.0611 ACTIVE BIAS CONTROLLER Typical Applications • Microwave Radio & VSAT • Military & Space • Test Instrumentation • Fiber Optic Modulator Driver Biasing • CATV Laser Driver Biasing •.

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.

Key Features

  • Automatic Gate voltage adjustment (No Calibration required) Supply Voltage: 4V to 12V Digital Voltage: 3.3V to 5V Controls both Enhancement and Depletion type devices Adjustable Drain Current up to 200mA Sink/Source Gate Current Capability Optional Internal negative voltage generation that can be disabled to use external negative rail Fast Enable/Disable Trigger-out Output for Daisy Chain Power-Up and Power-Down Sequencing 13 BIAS.
