摘要：

A modified Wilkinson power divider (PD) with improved in- band performance and compact size is proposed in this paper. Compared with conventional Wilkinson PD, such structure features with an additional shorted stub on the output port, which can introduce an extra transmission pole for in -band performance enhancement. Besides, the proposed Wilkinson PD adopts meander line for compact size. Furthermore, the isolation resistor is achieved with thin film resistance technology to avoid welding tolerance. To verify the mechanisms mentioned above, a modified Wilkinson PD operating at 7 GHz is designed and fabricated in size of 8.2mmx8.8mm (0.2 lambda(g)x0.19 lambda(g)), with significantly benefit of compact, wide-band, low loss and well in -band loss flatness characteristic. The measured fractional bandwidth (FBW) is 57.1% (i.e., 5-9 GHz) with insert loss of 3.2-3.4dB. Meanwhile, the return loss is less than 15dB.
