Abstract

In this paper, a double balanced mixer based on a novel planar balun with the operating frequency from 3.1 GHz to 10.6 GHz is proposed. This microstrip-to-slotline transition balun can block IF and DC components effectively in a wide band. Also, in order to provide better isolation, a compact low pass filter is connected to the IF port. As the measured results show, the mixer exhibits the conversion loss less than 15 dB with the IF up to 100 MHz and port-to-port isolation better than 25 dB. The proposed mixer can be applied in the ultra-wideband transmission systems.
