Abstract
In the UHF or VHF band, the new design method of small-sized 3-dB 0 de grees/180 degrees ring hybrid terminated by arbitrary impedances using both lumped and distributed elements is presented, At the center freq uency of 900 MHz, the small sized 3-dB 0 degrees/180 degrees hybrid te rminated by arbitrary impedances is designed, analyzed and tested, Goo d agreements are obtained between measured and predicted results. Sinc e both lumped and distributed elements are used, the proposed hybrid i s occupied about 30% of all distributed-type hybrid.
