Abstract :
Design, fabrication technology, and measured performance of a monolithic medium power amplifier are described. The circuit consists of four amplifier stages and operates over the 17 - 26 GHz frequency range. The impact of bond wires for hybrid mounting was taken into account in the circuit design. The MMIC was fabricated with a pseudomorphic HEMT technology requiring no electron beam lithography. More than 25 dB small-signal gain, 24 dBm output power, and an overall efficiency of 15 % have been obtained over the entire frequency range.
