High Current Active Bias Controller: HMC980
The HMC980 is a high current active bias controller that features automatic gate voltage adjustment.
This high current active bias controller is ideal for military and space applications, test instrumentation, cellular base stations, military radio and VSAT, fiber optics modulator driver biasing, and applications involving wireless infrastructure equipment and CATV laser driver biasing.
In addition to its automatic gate voltage adjustment, this controller features a 5V to 16.5V supply voltage, fast enable/disable, trigger out output for daisy chain, power-up and power-down sequencing, a sink or source gate current, an adjustable drain current up to 1.6 A, and more.
The HMC980 High Current Active Bias Controller 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.
