Compact, Low Weight dB-3814 Microwave Power Module Covers Wide Frequency Range; Designed for Airborne SAR and Multi-Mode Radars, EW Threat Simulation, Radar Countermeasures, Manned and Unmanned Platforms
PRWeb – Fremont, Calif. – dB Control Corp., an established manufacturer known for its reliable, high-power microwave amplifiers, radar/electronic countermeasure (ECM) transmitters and power supplies, is introducing the Model dB-3814, a pulsed Microwave Power Module (MPM) with instantaneous bandwidth operating in the 15 GHz to18 GHz frequency range and providing 1 kW peak power at 7% maximum duty cycle. Applications for this MPM include airborne synthetic aperture (SAR) and multi-mode radars, electronic warfare (EW) threat simulation, radar countermeasures and manned and unmanned platforms.
Radar detection systems such as EW threat simulators require high-power components that meet high- performance standards, including wide bandwidth, high pulse burst, extremely low phase noise and spurious, excellent amplitude, phase stability and more. dB Control specifically designed the dB-3814 to meet these requirements while operating reliably at altitudes of up to 40,000 feet, with a low operating base plate temperature of -40°C to +85°C to meet critical heat dissipation requirements.
“MPMs used onboard military airborne systems must be compact and low weight while providing maximum power and a high duty cycle. The dB-3814 provides more than twice the output power of comparable MPMs, and does so over a wider frequency range,” said dB Control Vice President of Technology and Business Development Meppalli Shandas. “Considering that we’ve increased the bandwidth and power without increasing the payload, this new MPM is sure to be in demand.”
The dB-3814 weighs 14 pounds and measures 12 inches by 10 inches by 3 inches. A periodic permanent magnet (PPM)-focused, conduction-cooled mini traveling wave tube (TWT) is used for power amplification and a solid state driver amplifier based on monolithic microwave integrated circuits (MMICs) is used to provide the required RF gain. A highly stable, solid state modulator is used for pulsing the TWT grid. The high-voltage power supply (HVPS) section uses modular architecture and low-noise power supply topology utilizing high-efficiency solid state power conversion circuits.
