Abstract
This letter presents a 77-GHz low conversion loss single balanced fundamental mixer based on the substrate-integrated suspended line (SISL) platform. The accurate 3-D EM model of the MA4E2038 Schottky diode is established to characterize the parasitic effects and perform the impedance extraction. At room temperature, the minimum measured conversion loss is only 4.47 dB. Different from the traditional metal waveguide process, this design was fabricated based on the SISL platform by the multilayer printed circuit board (PCB) process, which has the advantages of low-cost, miniaturization, and self-packaged, providing an alternative solution for the mixer application in 77-GHz radar system.
