This article deals with a design and performance evaluation of a medium power C‐band array amplifier based on SiGe hetero‐junction bipolar transistors (HBT). The proposed power amplifier (PA) contains four identical HBT stages coupled by the means of compact power splitting/summing microstrip networks. The designed PA exhibits a very low phase noise level of −165 dBc/Hz at 1 kHz offset frequency, and it is distinguished by a high output power having P 1dB = +26 dBm and high power added efficiency approaching to 40%. © 2009 Wiley Periodicals, Inc.
