dB Control, a supplier of mission-critical (often sole-source) products worldwide to military organizations, major defense contractors and commercial manufacturers, is introducing a new series of TWT rack-mount amplifiers. The dB-4051 K/Ka-Band TWTA operates in the 18 to 40 GHz frequency range and provides 50/60 Watts minimum continuous wave (CW) output power. The dB-4051A K/Ka-Band TWTA operates in the 17.5 to 40 GHz frequency range and provides 40/50 Watts CW/Pulsed minimum output power. Both rack-mount TWTAs are designed to be used for ECM transmitters, electronic warfare simulation, EMC tests, RFI susceptibility/RF components testing, and antenna pattern/radar cross section measurements.

“To meet size, weight and power requirements, customers want high-power amplifiers that support as much of the electromagnetic spectrum as possible in a single device. That’s why last year we introduced the 2 to 18 GHz dB-8015 Microwave Power Module. Design engineers also prefer the convenience of working with a single manufacturer that can provide high-power amplifiers covering the full 2 to 40 GHz spectrum. With the introduction of our new dB-4051 and dB-4051A TWT amplifiers, dB Control is the only company with that capability,” said dB Control Vice President of Sales and Marketing Mike Lee.

In both the dB-4051 and dB-4051A, a wide-band, periodic permanent magnet (PPM)-focused, conduction-cooled TWT is used for power amplification of CW, AM, FM or pulse-modulated signals. The power supply topology uses proprietary low-noise, high-efficiency designs to operate the RF signal path. An embedded microcontroller provides the interface, control and protection functions, as well as extensive fault diagnostics and status indication for the TWT amplifier. Standard communication interface is Ethernet. The dB-4051 and dB-4051 TWTAs are packaged in a standard 19-inch rack-mount configuration with an integral, forced air cooling system which can also be made available in an outdoor mount configuration.
