چکیده
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.
