ABSTRACT In this article, a new design of a Wilkinson power divider is presented that offers substantially improved amplitude and reduced size characteristics over a broad frequency range compared to a conventional Wilkinson power divider. The improvement in bandwidth is obtained by reducing inductance and number of lumped components in even mode. The analytical design equations for this proposed power divider are obtained using even and odd mode analysis. This power divider with a compact size is fabricated using 65 nm 1P9M CMOS technology. The measurement results show an operation bandwidth 26–40 GHz with 15 dB input, output return loss, and 0.7 dB insertion loss. © 2016 Wiley Periodicals, Inc.
