Design of compact wilkinson power divider with harmonic suppression for GSM application

摘要

This paper presents a design of a Wilkinson power divider (WPD) with compact size and harmonics suppression for GSM application. The stub loaded transmission lines are used instead of two conventional quarter wavelength transmission line in order to miniaturization of circuit area as well as harmonic suppression. Therefore size reduction of 42% with unwanted harmonic is suppressed with respect to operating frequency. The measured return loss and isolation performance are found to be around 15dB and 28dB, respectively.
