Abstract :
The study proposes a novel miniaturized wide-band Wilkinson power divider, based on 0.18 mum 1P6M CMOS foundry technology. The proposed two-dimensional transmission line, called a complementary-conducting-strip (CCS), replaces the conventional microstrip (MS) line structure. With this CCS structure, the occupying area of this novel divider is approximately 96% smaller than that of the conventional MS Wilkinson power divider. The prototype, including the input/output (I/O) pads, occupies an area of only 673 mum by 645 mum. The new WPD has a coupling loss of -5.4 dB, an isolation of +15 dB and a return loss -12.5 dB from 8.7 GHz to 17.4 GHz.
