We present the preliminary lab demonstration results of an oxygen differential absorption radar named DABAV (Differential Absorption Atmospheric V-band pressure radar) operating over a wide bandwidth in the V-band (65-70 GHz) using a compact architecture that reduces mass, power, size and development time.
We have been developing gallium nitride (GaN)monolithic microwave integrated circuits (MMICs) towards thegoal of implementing a single chip transceiver frontend forcloud radar arrays at Ka-band. We present our first iterationdesign, fabrication and test cycle implementation of GaN poweramplifiers (PAs), low noise amplifiers (LNAs), driver amplifier,single-pole- double and triple throw switches, and voltagecontrolled attenuator. These components are necessary forimplementing a transceiver unit cell concept with digitalcalibration capabilities to enable scalable array sizes for radarand radiometry.
