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.
Each TWTA has an embedded microcontroller with an Ethernet interface for control and protection. However, the fault diagnostics and status indicators are integrated in the amplifiers, so outside controllers and interconnect cabling are not required. The TWTAs can be configured with standard or custom interface protocols rather than Ethernet. Another available option is RF gain control.
Established in 1990, dB Control designs and manufactures reliable, high-power TWTAs, microwave power modules, transmitters, high voltage power supplies and modulators for radar, electronic countermeasures and datalinks. The company also performs contract manufacturing and repair depot services from its 40,000 sq. ft. facility, including transformer winding and testing, full vacuum encapsulation, pressure cure and conformal coating. A subsidiary of HEICO Corp., dB Control specializes in mission-critical - often sole-source - products to military organizations, defense contractors and commercial manufacturers.
