Microwave Power Module MANORSHI-3758
Product Description
The dB-3758 is an integrated pulsed microwave power module (MPM) operating in the X-Band providing 1000 Watts peak output power at a duty cycle of 6%. The RF signal path consists of a solid PIN diode modulator, solid state driver amplifier and a mini-TWT. The power supply topology uses proprietary low-noise, high-efficiency designs to operate the RF signal path. A highly stable, solid state modulator is used for TWT grid modulation. Synchronization of power supply switching frequency with a radar system clock and blanking during the pulse are two unique techniques used in this unit to make this suitable for extremely low phase noise radar transmitter applications. The dB-3758 has several additional features such as VSWR protection, remote interface with RS-422 and integrated forced air cooling. This MPM is designed to meet military airborne environments and has been used in military manned and unmanned platforms.
