An integrated equal-split Wilkinson power combiner/divider tailored for operation in the X-band is reported in this letter. The combiner features differential input/output ports with different characteristic impedances, thus embedding an impedance transformation feature. Over the frequency range from 8 to 14GHz it shows insertion loss of 1.4dB, return loss greater than 12dB and isolation greater than 10dB. It is implemented in a SiGe bipolar technology, and it occupies an area of 0.12mm2.

Abstract
An integrated equal-split Wilkinson power combiner/divider tailored for operation in the X-band is reported in this letter. The combiner features differential input/output ports with different characteristic impedances, thus embedding an impedance transformation feature. Over the frequency range from 8 to 14GHz it shows insertion loss of 1.4dB, return loss greater than 12dB and isolation greater than 10dB. It is implemented in a SiGe bipolar technology, and it occupies an area of 0.12mm2.
