LDMOS RF MCMs target 5G mMIMO radios to 4 GHz
Second generation RF MCMs offer increased efficiency of up to 45% at 2.6 GHz helping reduce the overall electricity consumption of the 5G network.

NXP Semiconductors has announced the availability of 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. Focused on accelerating the coverage of 5G, the new all-in-one power amplifier module family is based on NXP’s latest LDMOS technology that offers higher output power, extended frequency coverage, and higher efficiency—all within the same footprint as previous generation of MCMs.

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.

The AFSC5G26E38 Airfast module is a prime example of the increased performance delivered in the 2nd generation MCM family. The device 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 new AFSC5G40E38 addresses the 5G C-band from 3.7 to 4.0 GHz and has recently been selected by NEC Rakuten Mobile in Japan.
