Compact impedance-transforming 3-dB three-port power dividers with modified asymmetric impedance transformers (MCCTs)

Summary form only given, as follows. For size reduction and design flexibility, a modified impedance transformer (MCCT) is proposed. One of the MCCTs is compared with conventional compact impedance transformers and the compared results show that the bandwidth of one MCCT is 78.5%, while those of the conventional ones are 40% and 42.5%, respectively. Using the MCCTs, impedance-transforming 3-dB MCCT power dividers are fabricated within an area that is much less than a conventional Wilkinson power divider.
