摘      要：A circuit topology for high-order subharmonic（SH） mixers is *** phase cancellation of idle frequency components,the SH mixer circuit can eliminate the complicated design procedure of idle frequency ***,the SH mixer circuit can achieve a high port isolation by phase cancellation of the leakage LO, RF and idle frequency *** on the high-order SH mixer architecture,a new Ka-band fourth SH mixer is analyzed and designed,it shows the lowest measured conversion loss of 8.3 dB at 38.4 GHz and the loss is lower than 10.3 dB in 34-39 *** LO-IF,RF-LO,RF-IF port isolation are better than 30.7 dB,22.9dB and 46.5 dB,respectively.
