Abstract :
In this paper, a compact Ka-band microstrip integrated local-oscillator-mixer assembly used in projectile sensors is introduced. The overall configuration of microstrip circuit of this assembly is given. The functions of each component are described. The environment and reliability tests performed on this assembly were explored in detail, which include vibration, shock and temperature. The Ka-band local-oscillator-mixer assembly exhibits a 3.4-4.2 dB double side band (DSB) noise figure over a 2-GHz RF bandwidth. LO-to-RF isolation is greater than 27 dB over the range of operating frequencies. The frequency stability of the local oscillator with dielectric resonator used is less than 60 ppm/c0
