Abstract

Monolithic, 450‐μm tall, rectangular coaxial Gysel divider is presented in this article. The divider is fabricated by a surface micromachining process with six sequentially deposited copper layers. Athree‐port, resistor‐less divider has overall loss of 0.6 dB at 30 GHz, input port reflection coefficient better than −10 dB, and output amplitude and phase misbalances of ±0.18 dB and ±1.8°, respectively, throughout Ka‐band. The device is designed in a way that permits straightforward realization of a Gysel divider with integrated resistors. Electromagnetic and electrothermal analyses and design of the divider are conducted, and good agreement with measurements is obtained. © 2009 Wiley Periodicals, Inc.

## Abstract A new dual‐band structure is proposed for the Gysel power divider. The proposed divider features an extension line at the input and a stub line at the opposite end, both located along the symmetry plane and operating at the even‐mode excitation of the divider. The divider is analyzed ri
