摘要:	摘要： In this work, a miniature ultra-wideband (UWB) power divider (PD) is proposed. By implementing the transmission lines of a two-stage Wilkinson PD using bridged T-coils, very compact size with no reduction in bandwidth can be achieved. Specifically, a proposed UWB two-way PD with a center frequency f 0 =5.5 GHz is implemented using the commercial GaAs pHEMT process. The circuit size without pads is only 1.45 mm × 0.84 mm, which is about 0.027λ 0 × 0.016λ 0 at f 0 . The fractional bandwidth for 15-dB input/output return loss and isolation is 110%, and the in-band insertion loss is within 1.3 ± 0.36 dB. 其他題名： LMWC 出版者： New York, NY: IEEE 出版日期： 2012-08-01 出處： IEEE microwave and wireless components letters, 2012-08, Vol.22 (8), p.391-393 資源來源： IEEE Electronic Library (IEL) 版權： 2015 INIST-CNRS 識別號： ISSN: 1531-1309 識別號： EISSN: 1558-1764 識別號： DOI: 10.1109/LMWC.2012.2205231 識別號： CODEN: IMWCBJ
