Title:
SYNTHESIZER-DISTRIBUTOR
Document Type and Number:
WIPO Patent Application WO/2018/138919
Kind Code:
A1
Abstract:
A synthesizer-distributor comprises: a first impedance converter provided between a first port and a second port; a second impedance converter provided between the first port and a third port; and an isolation unit provided between the second port and the third port. The isolation unit is provided with: a balun configured by a first semi-rigid cable and a second semi-rigid cable; and a plurality of terminating resistors. The respective line lengths of the first impedance converter, the second impedance converter, and a third impedance converter are ¼ of the wavelength of the center frequency. When the impedance of the second port and the third port is Ri, the impedance of the first port is Ro, and the impedance of the first impedance converter and the second impedance converter is W, the relationship is W = (2 x Ri x Ro) ½.
