Teledyne Microwave Solutions (TMS) has announced a new line of wideband compact GaN amplifiers that operate from 0.1 GHz to 6.0 GHz frequency range. The new line consists of five GaN wideband amplifier models that raise the bar for SWaP (size, weight and power) in this category of GaN amplifiers while meeting the stringent airborne requirements of the most demanding commercial and military applications. The dimensions, excluding connectors, are 2.5”L x 2”W x .42”H, at only 2.1 cubic inches. The five models numbers are TSA-213241, TSA-213242, TSA-213243, TSA-213244 and TSA-213245.
TMS has leveraged its 50 year amplifier engineering heritage to create a modular, non-ITAR line of amplifiers that they can quickly and efficiently tailor to the specific needs of customers utilizing one of the industry’s most comprehensive repository of parts. With wider bandwidths that enable more design flexibility, the new GaN amplifier line offers a unique value proposition for the most demanding SWaP needs of today’s airborne markets.
This family of amplifiers was designed and manufactured with great attention to thermal requirements to ensure the high reliability required in the most demanding applications. With a calculated MTBF of over 40,000 hours @ +85° C, these units are suitable for airborne applications as well as challenging land based environments.
Depending on frequency band, output power ranges between 15 and 40 watts. Each amplifier includes preamp and driver stages to produce a minimum overall gain of 50 dB. Internal control circuitry ensures safe startup so supply voltages can be applied in any order. In addition to normal DC connections via a 15 pin Micro D connector, other convenient control / interface features available via the connector include a TX enable / disable TTL command (100 ns TYP, 200 ns MAX); over temperature automatic shutdown and associated alarm (TTL); and the ability to monitor unit temperature via an analog voltage which is proportional to case temperature.
