Ultra-Cool GaN on Diamond Power Amplifiers for SATCOM
Microwave Journal, Diamond Anniversary Issue + Semiconductors & Packaging, Vol. 61, 6th Ed.
The most advanced commercial satellites transmit data down to Earth at rates of 100 to 200 Mbps; some advanced larger single satellite concepts target 1 to 4 Gbps. These data rates are substantially limited by state-of-the-art RF power amplifiers used to make the transmitters. Akash is building, for the first time, a small satellite system (12U) that will exhibit a preliminary downlink data rate of 14 Gbps. The next demo will feature data rates of over 100 Gbps. The ultimate technical goal is…
The most advanced commercial satellites transmit data down to Earth at rates of 100 to 200 Mbps; some advanced larger single satellite concepts target 1 to 4 Gbps. These data rates are substantially limited by state-of-the-art RF power amplifiers used to make the transmitters. Akash is building, for the first time, a small satellite system (12U) that will exhibit a preliminary downlink data rate of 14 Gbps. The next demo will feature data rates of over 100 Gbps. The ultimate technical goal is to demonstrate a downlink data rate of 1 Tbps from a single, modest size satellite—using GaN on Diamond RF power amplifiers.

GaN-on-Diamond Field-Effect Transistors: From Wafers to Amplifier Modules
MIPRO 2010
We describe the development and issues related to fabrication, die processing, and packaging GaN-on-diamond high-electron mobility transistors into X-band amplifier modules. We perform thermal resistance measurements on these amplifiers using liquid-crystal thermography and show that they agree with theory and previously published measurements on GaN-on-diamond devices.
