Our evaluation boards showcases the flexible combinations of various controllers and switches currently offered. They can be integrated with matched GaN fixtures to demonstrate both RF and DC performance.

Multi-Stage Bias and Control, CW

High-Speed Power CMOS, Pulsed


The module has simple to complex functions depending on need. From basic sequencer to modulator, the tiny unit is a breeze to drop-in near the GaN transistor. They can provide cmos or TTL drive to a switch module. It can  function with or without a negative supply.
