Design of a down-Conversion Mixer for Four Sub-Harmonic in W-Band

Article Preview

Abstract:

This paper presents principles of a down-converted mixer for four sub-harmonic designed by ADS software. The LO and RF frequencies are 23GHz, 92-94GHz respectively. The structure of ridge waveguide to microstrip transitions is optimized by CST simulation software, and W-band signals are directed to mixer RF side. The simulation results show that this mixer achieves higher 1 dB compression point, loss of frequency conversion less than 15 dB and good linearity.
