Title:
【発明の名称】バラン設計による二相変調器
Document Type and Number:
Japanese Patent JP2001512929
Kind Code:
A
Abstract:
A double-balanced microwave biphase modulator circuit is provided with a first balun for transforming the unbalanced RF Input impedance to a balanced diode impedance and providing direct current ground return paths, and a second balun for transforming the balanced diode impedance to the unbalanced RF Output impedance and providing access for data input. The first balun consists of a transmission line attached from a coupled pair of transmission lines to ground. The second balun consists of three pairs of coupled transmission lines, in which the first two pairs of transmission lines are attached to a diode ring, to a data input filter, to a circuit ground, and to the third pair of transmission lines.
