Abstract
In this paper, a Balun-BPF with the balun and BPF characteristics is proposed by using dual-mode ring resonator of $1{\lambda}$. We obtained the property of balun with the phase imbalance by symmetrically placing each output of ring resonator. The dual mode has been made by impedance difference between input and output lines. The fabricated Balun-BPF shows bandwidth of 40 MHz and insertion loss of 2.4 dB at a center frequency of 2.45 GHz. It shows the phase imbalance of $180{\sim}184$ degree and the magnitude imbalance of within 1 dB. The measured frequency responses agree well with simulated ones.
