Abstract :
A simple balun having the structure of a Wilkinson divider is proposed, and a 77 GHz CPW balun, as an example, has been fabricated and measured. The input and output ports of the proposed Wilkinson balun form the desirable inline structure. Results show that the measured S21, S31, matching, and isolation are -4.5 and -3.7 dB, less than -15 and -20 dB with the exact out of phase between output ports.
