Product Description
The TMC261 is a three-stage GaN power amplifier developed for the downlink band in LEO satellites, designed to provide the optimal output power, efficiency, and linearity. Fabricated with a high reliability GaN process, the MMIC die measures 3.5 mm x 2.5 mm and is 0.1 mm thick. It is also offered in a 6 mm x 6 mm air-cavity QFN. The nominal drain bias is 18 V at 74 mA. The drain bias can be increased to 24 V to increase the output power to 2 watts while maintaining good efficiency and NPR.
