Advanced W-Band Gallium Nitride Monolithic Microwave Integrated Circuits (MMICs) for Cloud Doppler Radar Supporting ACE Project

<p> 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.<br /> Targeted GaN MMIC component performance goals are:<br /> Power amplifier (PA): 1 Watt with 12 dB gain.<br /> Low noise amplifier (LNA): &lt;6 dB noise figure with&nbsp;&nbsp;&nbsp;&nbsp; 17 dB gain.<br /> Single pole double throw switch (SPDT): &lt;3 dB insertion loss.<br /> Phase shifter: 4 bit resolution and &lt;8 dB insertion loss.<br /> Integrated MMIC chip with all transceiver front end functions.<br /> &nbsp;</p>
