Weatherproof High-Power TWTAs

dB Control Introduces Weatherproof High-Power TWT Amplifiers for Critical Military Operations; Pedestal-Mountable Amps Enable Maximum Mobility, Ideal for Training, Simulation and Electronic Warfare

BUSINESS WIRE] – Fremont, Calif. – dB Control, an established designer and manufacturer known in the industry for its reliable high-power microwave amplifiers, power supplies and radar transmitters, today announced two new high-power traveling wave tube (TWT) amplifiers. These include the dB-4102S and the dB-4103S, both of which are completely weatherproof and ideal for critical military operations.

The dB-4102S delivers 50 watts CW or pulsed output power and operates in the frequency range of 18 to 26.5 GHz. Input power is 1000 watts maximum. The dB-4103S delivers 40 watts CW or pulsed output power and operates in the frequency range of 26.5 to 40 GHz. Both TWTs are designed specifically for training and simulation and electronic warfare in a land environment.

For each of these new high-power TWTs, the amplifier is packaged in a split-mount configuration. The power supply and associated electronics is packaged in one configuration (8.75 by 19 by 24 HWD) and the RF assembly (11.5 by 6.2 by 23 HWD) is assembled in an environmentally sealed package suitable for mounting on an antennae pedestal. The two units can be separated by a maximum of 15 feet, and cooling is accomplished by internal fans. The TWTs operate at altitudes of up to 10,000 feet, in temperatures between -30 and +55 Centigrade, and in 100 percent relative humidity.

The dB-4102S and the dB-4103S also each feature a wide band, periodic permanent magnet-focused, conduction-cooled TWT for power amplification. The power supply section uses modular architecture and solid state circuits. An embedded micro-controller provides the interface, control and protection amplifier, and the standard interface protocol is RS-485.

“The dB-4102S and dB-4103S have already proven to be extremely rugged and versatile, and are ideal for training and simulation, as well as electronic warfare,” said Meppalli Shandas, vice president of marketing. “Each of these TWTs can be pedestal mounted into the bed of a truck, making them extremely flexible in a range of military scenarios, including extremely harsh conditions.”
