NXP's Ultra-Wideband Doherty Amplifier Demo
Roger Williams, NXP Semiconductors, gives a preview of NXP's Ultra-wideband Doherty reference design, which will be showcased at MTT-S International Microwave Symposium (IMS 2013) in Seattle, Washington from June 4-6 (Booth 1709).
NXP'
s new reference designs bring the high-efficiency gains of Doherty topologies to digital broadcast transmitters, using NXP's patent-pending architecture capable of operating over an ultra-wideband spectrum. Whereas traditional UHF technologies such as class AB typically reach only 30% efficiency, Doherty solutions are capable of reaching 45-50% power amplifier efficiency -- a significant improvement.
