ABSTRACT:
A frequency converter for a microwave system includes: a balun having a slot line connected in a parallel T-junction with a first microstrip line for receiving a radio frequency signal; first and second strip lines respectively disposed on either side of the first microstrip line; second and third microstrip lines respectively connected to outer ends of the first and second strip lines to provide signal paths for inputting local oscillation signals and for outputting intermediate frequency signals; first and second open end circuits respectively connected to both ends of the slot line, and a quad diode mixer bridge having a pair of diode connection points connected to the slot line and having another pair of diode connection points respectively connected to the second and third microstrip lines, the radio frequency signal and local oscillation signals being converted into corresponding intermediate signals therein.
