Abstract :
We report the development of a wideband uniplanar singly balanced diode mixer using a coplanar waveguide and a slot line. The first-design mixer has a measured conversion loss from 6 to 10 dB for the RF signal from 7.1 to 10. GHz and the LO signal of 3.5 dBm at 7 GHz. The LO-RF isolation is better than 20 dB, and the isolations from the IF to the LO and RF ports are more than 36 dB. This mixer circuit is simple and has a wide bandwidth and good interport isolations. Furthermore, its uniplanar nature allows solid-state devices to be mounted easily and no via-holes are needed for ground connections. These features are attractive for low-cost microwave and millimeter-wave integrated circuits.
