HIGH-GAIN WIDE-BANDWIDTH LOW NOISE AMPLIFIER MULTI-CHIP WAVEGUIDE MODULE AT V-BAND

A low-noise, high-gain, wide-bandwidth multi-chip module has been developed at V-Band with WR-15 waveguide interface using commercial-off-the-shelf (COTS) Low Noise Amplifier (LNA) Monolithic Millimeter-wave Integrated Circuits (MMICs). Waveguide module design ensures there is minimal impact on noise figure and gain of MMICs due to integration on the module and it is rugged to sustain impact of fabrication/assembly tolerances. The realized six-stage LNA module has small-signal gain of 32-35 dB and room temperature noise figure ranging from 2.2 to 4.4 dB in 50-60 GHz frequency band. The module design has been simulated using 3D electromagnetic solver High Frequency Structure Simulator (HFSS). (C) 2016 Wiley Periodicals, Inc.
