Design of the Single Balanced Mixer (Using HSMS-281x Diode) and Measurements

Abstract

We designed the Mixer operating at 2.4 GHz for WIFI-band using ADS software and fabricated using Rogers 4350B substrate. We designed the single-balanced mixer using the diode (HSMS-281x model). We measured the isolation across all ports of the mixer. We measured the conversion loss of the mixer. We performed the non-linear measurements, which include IM3 vs frequency. The performance metrics are compared with the data-sheet values and explained if any discrepancy exists.
