Teledyne Microwave Solutions’ new wideband, modular GaN amplifiers lower the form factor threshold for 0.1 to 6 GHz. At only 2.1 cu in (2.5" long × 2" wide × 0.42" high), this non-ITAR amplifier line maximizes power density and efficiency, while maintaining the rugged characteristics necessary for harsh airborne requirements.

Teledyne Microwave Solutions (TMS) leveraged its 50 year amplifier engineering heritage to create a line of GaN amplifiers that can quickly be tailored to the specific needs of customers, utilizing one of the industry’s most comprehensive repositories of parts. With wider bandwidths that enable more design flexibility, the amplifiers were designed and are manufactured with great attention to the thermal requirements needed for high reliability. The calculated MTBF is greater than 40,000 hours at +85ºC, making the amplifiers suitable for airborne applications and challenging land environments.

Depending on the frequency band, the output power ranges from 15 and 40 W. Each amplifier includes preamp and driver stages to produce a minimum gain of 50 dB. Internal control circuitry ensures safe startup, so supply voltages can be applied in any order. In addition to normal DC bias, the 15 pin Micro-D connector provides other convenient control and interface features, including a TTL Tx enable/disable command (100 ns typical and 200 ns maximum switching time), an automatic over temperature shutdown and alarm (also TTL) and the ability to monitor unit temperature via an analog voltage proportional to case temperature.

The new line consists of five base model wideband, GaN amplifiers: TSA-213241, TSA-213242, TSA-213243, TSA-213244 and TSA-213245. Contact TMS to discuss modifications to meet your exact requirements.
