Abstract:	摘要： In this study, a miniature bandpass power divider based on capacitive-loaded multicoupled line is proposed, which features equal-ripple insertion loss, return loss and isolation responses. Owing to the employment of capacitive-loaded transmission line resonators, it can achieve very compact size and wide upper stopband. The proposed bandpass power divider can be designed, according to the conventional filter synthesis techniques, and is suitable for on-chip implementation. Specifically, a bandpass power divider with a centre frequency f^sub 0^ of 5.5 GHz, 18.2% fractional bandwidth, and third-order equal-ripple response is designed and implemented, using the commercial GaAs pseudomorphic high electron mobility transistor process. The circuit size without pads is 0.87 mm x 0.95 mm, and the electrical size is only 0.057 λ^sub g^ x 0.062 λ^sub g^ at f^sub 0^. The in-band insertion loss is less than 6 dB with a minimum insertion loss of 5.12 dB. The in-band return loss is better than 10 dB, and the isolation is better than 15 dB. 出版者： Stevenage: Institution of Engineering and Technology 出版日期： 2012-10-23 出處： IET microwaves, antennas & propagation, 2012-10, Vol.6 (13), p.1461-1467 版權： 2014 INIST-CNRS 版權： Copyright The Institution of Engineering & Technology Oct 2012 識別號： ISSN: 1751-8725 識別號： EISSN: 1751-8733 識別號： DOI: 10.1049/iet-map.2012.0091
