NXP unveils 2nd Generation RF multi-chip modules

1 min read

NXP Semiconductors is making available its 2nd generation of comprehensive Airfast RF power Multi-Chip Modules (MCMs) designed to support the evolution of 5G mMIMO active antenna system requirements for cellular base stations.

Designed to focus on accelerating the coverage of 5G, the all-in-one power amplifier module family is based on NXP’s latest LDMOS technology that offers higher output power, frequency coverage, and efficiency - all within the same footprint as NXP’s previous generation of MCMs.

The AFSC5G26E38 Airfast module delivers 20% more output power compared to the previous generation, addressing the need for broader 5G coverage per base station tower, without increasing the radio unit size. It also features a power-added efficiency of 45%, 4 points higher than the previous generation for an overall reduction in the 5G network electricity consumption. Highlighting the performance of NXP’s latest LDMOS generation in high frequencies, the AFSC5G40E38 addresses the 5G C-band from 3.7 to 4.0 GHz and has recently been selected by NEC Rakuten Mobile in Japan.

“NXP’s latest multi-chip modules provide an efficiency boost resulting from the latest enhancements to LDMOS and enhanced integration,” said Paul Hart, Executive Vice President and General Manager of NXP’s Radio Power. “Our aggressive drive for integration brings more features into each module, which means fewer components for our customers to source, assemble and test. The result is a higher power yet more cost-effective, compact design. This translates into faster time to market for our customers and mobile network operators who are tackling the need for 5G expansion.”

NXP’s RF power Multi-Chip Modules include LDMOS ICs, paired with an integrated Doherty splitter and combiner and a 50-ohm in/out matching. This level of integration removes RF complexities and eliminates multiple prototype passes, while the reduction of component count helps improve yields and decrease qualification cycle time. The 2nd generation complements the initial series released last year, extending the frequency and power levels. Both share the same pin-out format to enable RF designers to quickly scale from one design to another, reducing overall development time.

The 2nd generation of Airfast MCMs is comprised of 10 new devices covering 5G frequency bands from 2.3 to 4.0 GHz, from 37 to 39 dBm average output power. The devices are qualified now and will be supported by NXP’s new RF Circuit Collection, a digital library of RF power reference circuits.
