Altum RF published a White Paper on GaN Ka-band Amplifiers for Satcom Applications in Microwave Journal in Microwave Journal
Abstract
This white paper offers an overview of the advantages of gallium nitride (GaN) for high and moderate power levels in Ka-band satellite communications applications. The paper includes a discussion of the RF power amplification challenges presented by Ka-band data transmission, including the need for high power transmission, wide bandwidth and high linearity. Altum RF’s family of GaN amplifiers is presented, with illustrations of how these components suit specific scenarios within Ka-band satcom applications. The paper concludes with a demonstration of the importance of accurate modelling of electrical and thermal effects for these applications, given the high power levels and high frequencies required.
