Imaging of temperature and humidity profiles of the atmosphere on a global scale with high temporal and spatial resolution requires a large aperture millimeter wave radiometer on geostationary orbit. We developed a prototype 50 GHz millimeter wave synthetic aperture radiometer and Low Noise Amplifier (LNA) MMICs and receiver technology for a 180 GHz synthetic aperture system. The 50 GHz system was tested in laboratory and in field with a 4-meter target disk by refocusing the array to near-field by digital phase corrections. The 180 GHz system development included novel 180 GHz MMIC LNAs that provide more than 100 GHz of bandwidth with more than 15 dB of gain and a noise figure of 3.7 dB.

In order to further improve the sensitivity and resolution of radiometer front-ends and also astronomy applications, amplifiers are needed with the lowest noise figure and high flat gain in G-band frequency range. Hence, we designed and demonstrated a MMIC LNA using Agilent EEHEMT model of 0.07 μm InP HEMT for operating at 120 210 GHz frequency broadband range. Simulation results illustrate smooth gain greater than 23 dB and noise figure about 1.5 dB across the bandwidth at 290 K according to IEEE standard ambient temperature. Input and output return losses are greater than 10 dB and LNA is unconditionally stable at its operating frequency range. Validation of performance for designed MMIC LNA was investigated from many aspects by simulation and measurement results which were done for MMICs InP HEMT technology during last years.

“…The 183 GHz receivers were developed under ACT-05 "Miniature MMIC Low Mass/power Radiometer Modules for the 180 GHz GeoSTAR Array (MIMRAM)" [4] and underwent several improvements for GeoSTAR-II including improved cavity alignment and mechanical strength. Careful on wafer screening of both the LNAs and mixers MMICs was performed, and a total of 50 MIMRAMs were produced at JPL.…”

The Geostationary Synthetic Thinned Aperture Radiometer (GeoSTAR) team recently concluded its second Earth Science Technology Office (ESTO) IIP-07, "GeoSTAR technology development and risk reduction for PATH". The major accomplishments during this project at JPL were:1) Demonstrate performance and scalability of the 183 GHz receivers 2) Local oscillator phasing architecture and technology 3) Subarray design validation including feedhorns, manifolds and alignment 4) System demonstration of signal distribution topology and measurements. Significant progress has been made to retiring risk of the various subsystems.
