Abstract :
The paper presents the design and realization of a novel 23 GHz sub-harmonic mixer using an input diplexer. The measured performance of the 23 GHz SHM is as follows: RF of 22.1-23.5 GHz; IF band larger than 1.4 GHz; LO working frequency can be selected at any frequency in the band of 1 GHz at the center of 10 GHz. The conversion loss is 8.7 dB. The isolation among LO, IF and RF is greater than 30 dB. The design techniques are attractive for designing a high port isolation sub-harmonic mixer.
