Abstract—The present paper focuses on an innovative broadband millimeter- wave single balanced diode mixer which is designed through using a newly designed substrate integrated waveguide (SIW) 90° coupler. The low cost singlebalanced mixer has its own advantages of low cost, low profile, and high performance. In addition, it has a less conversion loss of 6.6 dB, a wide-band response from 9.5 to 12.5 GHz and better than -20dB port-to-port isolations.
Index Terms—Substrate integrated waveguide (SIW), single-balanced mixer, coupler, conversion loss.
