Nitronex has partnered with Prescient Wireless to develop a broadband Doherty power amplifier for WiMAX applications. Based on Nitronex's NPT25100, the design provides 20W linear power from 2.5 to 2.7GHz while achieving over 30% efficiency, and 2% EVM with digital pre-distortion.
"We are excited to achieve the 20W milestone using our GaN-on-Si power transistor technology. Customers asked us to increase our power levels while further reducing our industry-leading price point for WiMAX power amplifiers. These results show our commitment to meet their needs," said Ray Campton, Marketing Director at Nitronex. "Prescient Wireless' expertise in power amplifier design allows us to deliver a reference design with instant credibility in the wireless infrastructure field."
Typical performance numbers were taken using a mobile WiMAX waveform defined as single carrier OFDMA 64-QAM ≤, 10MHz channel bandwidth, 9.5dB PAR @ 0.01% probability during the transmit portion of a 50% duty cycle TDD signal.
The reference design consists of the schematic, bill of materials, circuit board layout files, detailed performance data, and other documents describing the design. Built and tested Doherty application boards are available for a suggested resale price of $1950. Reference design documentation and other information are available on the Nitronex web site at http://www.nitronex.com/design_support.
