A four‐device broadband solid‐state power amplifier, which is based on radial waveguide power‐dividing/combining circuit, has been investigated in this work. The fabricated power amplifier combining four monolithic microwave integrated circuit power amplifiers shows a 12–16.6 dB small‐signal gain over a broadband from 6 to 14 GHz. The measured maximum output power at 1 dB compression is 25.6 dBm at 10 GHz, with a high power‐combining efficiency of 96%. © 2008 Wiley Periodicals, Inc.
