Abstract
In this article, computer‐aided design of a broadband single balanced waveguide mixer covering full K‐band (18 to 26.5 GHz) is presented.Emphasis has been given on simple design approach of the mixer using commercially available CAD (computer‐aided design) tools. The mixer circuit is implemented on suspended stripline etched on soft substrate that is integrated with RF (radio frequency) and LO (local oscillator) waveguides. Conversion loss of 6–8 dB with 8.5 GHz instantaneous IF (intermediate frequency) bandwidth has been achieved with +10 dBm LO power at 35 GHz and the RF swept from 18 to 26.5 GHz. A systematic design approach of the mixer is presented with its simulated and experimental results. © 2011 Wiley Periodicals, Inc.
