Abstract :
An enhancement technique for miniaturized Wilkinson power divider is proposed in this paper. The design uses capacitance loading at the input and output ports of the device to achieve size reduction. Broadband characteristics are obtained through the addition of a compensation capacitor between the two output ports. The 11 GHz enhanced Wilkinson power divider is fabricated using a planar microstrip process on GaAs substrate. The occupied area of the device is 0.28 mm /spl times/ 0.76 mm. The measured bandwidth for which the input return loss is better than 15 dB is 60.8 % with an insertion loss on this bandwidth not greater than 0.43 dB and a phase deviation less than 0.12/spl deg/.
