Analysis and design of microwave T-junction circuits for prescribed response characteristics

The T-junction is a fundamental passive component in microwave and millimeter-wave monolithic circuits and the characterization of its transmission and reflection properties is a topic of considerable interest. The full-wave spectral domain analysis of Wu et al. (1990) has been applied to obtain the scattering parameters as a function of frequency for an uncompensated T and a shaped T (used as a broad-band equal-power divider) which show excellent agreement with measured results. We have employed a computer oriented technique which provides optimized design for prescribed transmission and reflection responses. The process is also extended for an unequal-power divider design.<
