nanoMPM Image

The nanoMPM® from Stellant Systems are Power Amplifiers that operate from 10.75 to 12.75 and 17.3 to 21.2 GHz. They deliver a saturated output power of 60 W, and a linear output power of 30 W and have an efficiency of 35%. These amplifiers leverage the best of solid-state and TWT vacuum technology and utilize a high-gain pre-distortion solid-state linearizer, four wideband high-power mini-TWTs, and a proprietary compact nanoMPM® EPC. They have been specifically designed to enable the next generation of software-defined satellites utilizing phased-array antennas for increased flexibility while on-orbit. The amplifiers require a DC supply of 100 V. They are available in a module that measures 23.4 x 6.4 x 3.1 cm (2x Dual TWT Modules per Quad) and are ideal for space applications.
