Abstract
One of the most specific military needs in microwave power amplification is wide band capability. Indeed, in order to fulfil electronic warfare specifications, amplifiers have to provide (from S- to Ku-band) a high level of output power taking into account Power Added Efficiency (PAE) and cost. Results obtained on MMICs (HBT devices) and TWTAs (MPMs) are presented in the 6-18 GHz instantaneous bandwidth. Current and anticipated results show that systems designer will have to take major improvements into account: this will lead to extensive competition in the near future between these two technologies.
