Abstract :
A novel wideband balun has been developed for MMIC (monolithic microwave integrated circuit) applications. Simple RF reflection and coupling principles are used to achieve a wideband performance in a simple microstrip configuration. The design was intended for 8- to 18-GHz wideband mixer applications. According to the predicted performance the insertion loss was better than 2 dB from 7 to 19 GHz, the amplitude balance was less than 1 dB, and the phase balance was less than 5 degrees from the 180 degrees phase difference. Experimental results show very good agreement with the predicted performance.<>
