The dB-3774B is a pulsed microwave power module (MPM) operating in the 6 to 18 GHz frequency range. It provides 1 kW peak power at 5% maximum duty cycle and is designed for high-performance electronic warfare applications. A periodic permanent magnet (PPM)-focused, conduction-cooled mini traveling wave tube (TWT) is used for power amplification.
An included solid-state driver amplifier provides the required RF gain. The high-voltage power supply (HVPS) section uses modular architecture and low-noise power supply topology, utilizing high-efficiency, solid state power conversion circuits. A highly stable, solid state modulator pulses the TWT grid. The conduction-cooled dB-3774B MPM operates with 270 VDC prime power.
