This Letter presents a design of microstrip filtering power divider for dual-band application. The proposed dual-band filtering power divider is based on the traditional Wilkinson power divider and employs T-junction structures and quarter-wavelength stepped impedance resonators (SIRs) to realise dual-band power allocation and bandpass response simultaneously. The design process is simple and effective...
The design of an unequal termination power divider (PD) with a bandpass filtering response and wide out-of-band suppression characteristics is presented. The two-cascaded coupled lines can be designed with a low impedance transforming ratio. For the validation, a 50-to-5 Ω termination impedance PD was implemented at a centre frequency (f0) of 2.6 GHz. The measured results are in good agreement with...
