Abstract

This article presents a dual-band amplifier with flexible frequency ratios. The amplifier features novel Wilkinson power divider/combiner with dual-band property that allows large frequency ratio (2.16-4.9) between its first and second operating bands. The measured combining efficiency on a stand-alone combiner is 97% at 2.25 GHz and 75% at 5.25 GHz. A 2.25/5.5 GHz prototype amplifier is tested to verify dual-band functionality. Measured linear gains are 12.85 dB and 12.07 dB at the first and second frequency bands, respectively.
