A 2GHz Balanced Mixer Using SOT-23 Surface Mount Schottky Diodes

A series of general purpose RF Schottky diodes has been introduced in the SOT-23 package. One of these diodes, the HSMS-2822, is a matched series pair, an ideal configuration for a balanced mixer. This note describes the procedure for designing the impedance matching circuit for a 2GHz mixer using the HSMS-2822. A conversion loss of 6.6dB was achieved
