Advanced W-Band Gallium Nitride Monolithic Microwave Integrated Circuits (MMICs) for Cloud Doppler Radar Supporting ACE
Project Introduction
Develop W-band Gallium Nitride (GaN) MMICs to enable the advanced cross-track scanning, dual-frequency Doppler cloud radar concept in support of the Aerosol-Cloud-Ecosystem (ACE) mission.
Targeted GaN MMIC component performance goals are:
Power amplifier (PA): 1 Watt with 12 dB gain.
Low noise amplifier (LNA): <6 dB noise figure with 17 dB gain.
Single pole double throw switch (SPDT): <3 dB insertion loss.
Phase shifter: 4 bit resolution and <8 dB insertion loss.
Integrated MMIC chip with all transceiver front end functions.
