Abstract :
A 2-18-GHz phase splitter network has been designed and developed to provide two outputs 180 out-of-phase, with a low insertion loss. The network consists of an active, 2-20-GHz, in-phase power divider, implemented in MMIC (monolithic microwave integrated circuit), the two outputs of which feed bandpass filter networks which have identical amplitude response, but are 180 degrees out-of-phase. The filter network has been modified in a novel fashion to make it MMIC-compatible. The network has applications in double-balanced mixers, Class AB power amplifiers, push-pull amplifiers, etc.<>
