Doherty architecture operates over an ultra wideband spectrum

NXP Semiconductors N.V. has developed new Doherty architecture capable of operating over an ultra wideband spectrum without an increase in the bill of materials. This high-efficiency solution uses NXP’s leading edge 50 V LDMOS technology and supports the full UHF band without any compromise in power and cost.

NXP says it has a very strong leadership position in Doherty architectures – the company has an extensive Doherty IP portfolio and employs the world’s leading expert in this area. NXP helps its customers by providing flexible Doherty reference designs to fit specific customer timing and performance criteria (such as efficiency and bandwidth) in the UHF band.

“We believe that the new ultra wideband variant of Doherty will have a major impact on the digital broadcast market,” said Mark Murphy, director of marketing, RF power and base stations, NXP Semiconductors. “Today's high-performance TV transmitters constitute serious investments, and so our customers need to implement higher efficiency solutions without incurring extra costs, and without delaying time to market. For this challenge to be met, the market needs suppliers who not only provide leading-edge products in areas such as Doherty power amplifiers, but can also offer expert application support to match. This is exactly where NXP fits in.”
