Abstract
With an increasing interest in backwards
compatibility for existing satellites and the emerging satellite
markets, wireless transceivers at Ku band are increasing in
popularity. This paper presents the design of a four-way digitally
driven Doherty amplifier, aimed at applications in Ku-band.
Single tone measurements indicate a maximum drain efficiency of
53.4% at a maximum of 19.2 dBm output power. The final output
power can readily be adjusted by changing the biasing in each
stage accordingly. The N-way Doherty power amplifier was tested
with an 800 MHz bandwidth, 64 QAM test signal aimed for future
communication signal standards. An analysis of this configuration
has also been performed for 2-way, 3-way and 4-way architectures.
