Multiport Power Amplifiers for Flexible Satellite Antennas and Payloads

Use of multiport power amplifiers in satellite transponders allowing higher edge of coverage gains and more efficient use of the frequency spectrum
In the last few years, the architectural design of satellite communications payloads has benefited from the view point of flexibility, from the adoption of Multiport Power Amplifiers (MPA). Multiport power amplifiers offer a means to combine discrete amplifiers in a way that is reconfigurable and will degrade gracefully in...
