dB Control offers two rack-mount traveling wave tube amplifiers (TWTA) for electronic warfare simulation, RFI testing and other applications requiring 300 to 325 W power in the 2 to 18 GHz range. The dB-4345 TWTA provides 325 W CW output power with 55 dB minimum gain across 2 to 6 GHz, and the companion dB-4311M covers 6 to 18 GHz, providing 300 W CW output with 55 dB minimum gain. Using a wideband, periodic permanent magnet focused, conduction-cooled TWT, the amplifiers support CW and constant envelope, AM, FM and pulse-modulated signals. The TWTA power supply is a low noise, high efficiency design that minimizes any interference to the RF signal path. Both models operate from single phase, 220 VAC power, although the prime power can be customized.
