【 摘 要 】

References(10)This paper presents a compact Wilkinson power divider with enhanced harmonics suppression. By replacing the quarter-wavelength impedance transformers in the traditional Wilkinson power divider with modified T-type impedance transformers (MTITs), three transmission zeros can be created at the second, third and fourth harmonic frequencies. The impedance transformers are folded to reduce the size of the power divider. For validation, a power divider operating at 1 GHz is implemented. Results indicate that the proposed structure can effectively be used for high order harmonics suppression while maintaining a good in-band performance and compact size.
