Abstract
In the UHF or VHF band, the new design method of a small-sized 3-dB 0°/180° ring hybrid terminated by arbitrary impedances using both lumped and distributed elements is presented. At the center frequency of 900 MHz, the small sized 3-dB 0°/180° hybrid terminated by arbitrary impedances is designed, analyzed and tested. Good agreement is obtained between measured and predicted results. Since both lumped and distributed elements are used, the proposed hybrid occupies about 30% of an all distributed-type hybrid
