IGNP2731M400 is a 50-Ohm matched GaN-based pulsed power module (aka pallet) for S-band radar systems operating in the 2.7-3.1 GHz instantaneous frequency band. This module supplies a minimum of 400W of peak pulsed output power under the conditions of 300µs pulse width and 10% duty cycle. The module utilizes RF-activated gate bias switching circuitry for noise blanking during pulsed-RF operation. All units are 100% screened for large signal RF parameters.
