Microwave Power Module
The dB-3758 is an integrated pulsed microwave power module operating between 9 and 10 GHz, providing 1 kW peak output power at a duty cycle of 6%. The RF signal path consists of a pin diode modulator, a solid-state driver amplifier and a mini-TWT. The power supply uses proprietary low-noise, high-efficiency designs to operate the RF signal path and a solid-state modulator is used for TWT grid modulation. The MPM synchronizes power supply switching frequency with a radar system clock and blanking during the pulse to make it suitable for low phase noise radar transmitter applications. Other features include VSWR protection, an RS-422 remote interface, and forced air cooling. The module is designed to meet military airborne environments and has been used in military manned and unmanned platforms.
