UWB Doherty reference design using NXP's BLF884P and BLF884PS power amps

NXP Semiconductors N.V. has made available of its ultra-wideband Doherty reference design using its wideband Doherty power amplifiers BLF884P and BLF884PS.

“By leveraging NXP’s expertise and IP in Doherty architectures, we’ve been able to design a unique ultra-wideband Doherty solution which achieves high efficiency without incurring additional costs, or delaying time to market: With a single Doherty design, we’re able to cover the full band from 470 to 806 MHz. In testing our first high-bandwidth Doherty power amplifiers, our lead customers have been able to demonstrate tremendous efficiency gains, further validating our approach,” said Mark Murphy, director of marketing, RF power and base stations, NXP Semiconductors. “Given the immense pressure to deliver richer content via high-performance TV transmitters, we believe that the impact of ultra-wideband Doherty architectures on the overall digital broadcast market will be wide-ranging. At an average DVB-T power level of 70 W, the BLF884P/PS ultra-wideband Doherty reference design is extremely well suited for gap filler applications.”

The BLF884P and BLF884PS are now in production, with product samples and reference designs available immediately to qualified customers of NXP.
