摘要：
This article presents two miniature impedance matching Wilkinson power divider circuits in 0.35 mu m SiGe BiCMOS technology for on-chip power combining techniques for WLAN applications. The impedance matching Wilkinson power divider circuits are used as splitter/combiner for a 5.2 GHZ fully integrated class-A mode combined power amplifier. The splitter and combiner are designed to match the input and output impedances of the amplifier, respectively, so that no additional impedance matching is needed. Two fabricated impedance matching Wilkinson power divider circuits (splitter and combiner) have insertion losses better than 1.4 dB, return losses less than - 13 dB and port-to-port isolation >12 dB at 5.2 GHg (C) 2009 Wiley Periodicals, Inc.
