Abstract-A new approach to design of a dual-band power divider with single transmission-line section is proposed in this paper. Apart from the isolation resistor, admittance matrix is used to synthesize the dual-band divider. According to the required admittance matrixes at two frequencies, a modified configuration with shunting open/short stubs at each port is presented. A new compact dual-band power divider (operating at 1.0 GHz and 4.5 GHz) is developed to validate this proposal. Experimental results demonstrate that the return loss is better than 19.2 dB, insertion loss less than 0.59 dB, and isolation better than 23.61 dB at two operation frequencies. The measured relative bandwidths of 15 dB return loss are 35.9% and 12.4% for the lower and higher bands, respectively.

A novel compact dual-band power divider with filtering responses is presented in this article. The proposed circuit utilizes coupled quarter-wavelength steppedimpedance resonators. By controlling these resonators, dual-band operation can be realized. Furthermore, a resistor is connected between the two open ends of the input feed line to obtain good isolation at two bands. Source load coupling is utilized to enhance the selectivity. To verify the proposed idea, a filtering power divider with the operating frequencies of 2.4 and 5.8 GHz is implemented. Good agreement between the simulated and measured results validates the proposed idea. The total size of the circuit is 0.23k g 3 0.28k g , where k g is the guide wavelength of 2.4 GHz.

A novel differential power divider with bandpass filtering response using the substrate integrated waveguide (SIW) technology is presented. An SIW resonant cavity operated in a balanced resonant mode with odd symmetric electric field distribution is utilized to provide both balanced inputs/outputs and expected common-mode (CM) suppression in a certain band. Meanwhile, by properly constructing the cross-coupled topology of SIW resonant cavities, the proposed differential power divider achieves a high-selectivity bandpass filtering response with two transmission zeros on both sides of the passband. The differential power divider is designed and prototyped on a single-layer printed circuit board (PCB). The measured center frequency is at 10.6 GHz with 490 MHz 3-dB bandwidth. A good CM suppression can also be achieved within the operating band. The measured in-band differential-mode imbalance for magnitude is 60.3 dB, while for phase is 08-48.
