RF Amplifier by dB Control

Note : Your request will be directed to dB Control.

The dB-3774B from dB Control is a pulsed microwave power module (MPM) that operates from 6 to 18 GHz and provides 1 kW of peak power at 5% max duty cycle. Designed for high-performance electronic warfare applications like radar jamming, this MPM features a conduction-cooled mini traveling wave tube (TWT) for power amplification and a solid-state driver amplifier for RF gain.

The high-voltage power supply section of the dB-3774B uses modular architecture and low-noise power supply topology. Additionally, the conduction-cooled dB-3774B MPM operates with 270 VDC prime power, resulting in the best efficiency in DC operation (with options for 28 VDC and 115 VAC 3 phase). Custom frequency bands are available.

This amplifier is available in a module that measures 18 x 7 x 3 inches and weighs 18 pounds.
