Low phase noise K-Band oscillator on organic Liquid Crystal Polymer (LCP) substrate

Abstract

In this paper, for the first time, a reflection type K-band oscillator, on low-cost Liquid Crystal Polymer (LCP), organic substrate, is presented. The oscillation frequency is determined by a λ/2 microstrip resonator coupled to a microstrip line. The measured phase noise and power output of the oscillator are found to be −108 dBc/Hz at 1 MHz offset and −6 dBm respectively, for an oscillating frequency of 25.6 GHz.
