Development of a Liquid Crystal Polymer low noise amplifier module at Ka-band

Abstract

The design and development of a Liquid Crystal Polymer (LCP) low noise amplifier module with an integrated waveguide input at Ka-band is presented. The LCP module houses two low noise amplifiers and an integrated band-pass filter. The integrated waveguide input transition to a microstrip achieves a measured insertion loss of 0.2 dB to 0.3 dB from 27 to 31 GHz. The LCP module has a measured noise figure of ~2.5 dB and a gain of 30 dB.
