Damian McCann, CTO, Mimix Broadband, Inc. In bath communications and radar systems, phased array antennas are increasingly being favored over conventional mechanically-scanned systems.
Applications in military scenarios, using active electronically-scanned arrays (AESA) require an efficient source (or sources) of microwave power. Today and into the foreseeable future, RF semiconductor power amplifiers (mainly MMICs) are used to supply the required power to each individual element in the active array. At Mimix we have successfully used commercially available GaAs foundry technologies to extend the power added efficiency (PAE) of Ku-band and Ka-band power ...
