Xilinx Inc. and NXP have joined forces to cut CapEx and OpEx costs of wireless infrastructure radios. According to the two companies, they have been working together to allow customers to quickly and easily combine Xilinx's latest crest factor reduction (CFR) and digital pre-distortion (DPD) SmartCORE IP with NXP's Gen9 LDMOS RF highly efficient power amplifier technology.

The combination of NXP's advanced power amplifier devices and Xilinx All Programmable devices and radio IP enables customers to implement smaller, lighter and higher reliability radios geared for next-generation wireless infrastructure equipment, the companies added.

Power amplifiers of higher efficiency achieve the same radio output power and enable a CapEx saving through the use of lower power rated devices and reduced cooling mechanics. Xilinx's Zynq-7000 All Programmable SoC claims to be the first hardware and software programmable device supporting the latest generation of CPRI at 10.1Gb/s and JESD204B at 12.5Gb/s line rates. The Zynq device also enables integration of advanced signal processing algorithms such as CFR and DPD with ARM processor-based control plane software for remote radios, distributed antenna systems and repeater products. In addition, smaller heat sinks enable a reduction in power supply complexity and weight for designers implementing their entire digital radio in a single chip.

Xilinx's latest CFR and DPD IP support up to 100MHz of radio bandwidth in single RAT configurations in addition to supporting MC-GSM with frequency hopping in single RAT or multi-RAT configurations up to 75MHz. Coupled with NXP's Gen9 family of RF power transistors targeted for compact, efficient and high-performance LTE base stations, Xilinx radio IP enables customers to implement advanced radio architectures with fewer resources in less time and achieve power amplifier efficiency of up to 50 per cent at 2.6GHz.

NXP's Gen9 family of RF power transistors is specifically focused on compact, efficient and high-performance LTE base stations. Building on the excellent reputation already established by previous LDMOS generations, Gen9 delivers unprecedented efficiencies and excellent linearisation capabilities for RF power amplifiers, at an industry-leading cost point. These ground-breaking devices represent a further step-up in performance for LDMOS transistors, having shown up to five per cent more efficiency in Doherty applications.

The Xilinx PC-CFR V6.0 SmartCORE IP solution is available for early access customers, and general availability is expected in January of 2015. The Xilinx DPD V7.0 SmartCORE IP is also available for early access customers with general availability expected January 2015.
