MACOM Launches GaN-on-Si MMIC Power Amplifiers for Massive MIMO 5G

MACOM has announced that its new MAGM series of GaN-on-Si-based MMIC power amplifiers are optimized for massive MIMO antenna systems targeting 5G wireless basestation infrastructure. These GaN-on-Si based power amplifiers deliver GaN performance at LDMOS-like cost structures at scaled volume production levels in fully integrated MMIC packaging for simplified, cost-effective 5G basestation manufacturing. The amplifiers cover bands 42 and 43 with flat power and high power efficiency compared to legacy LDMOS technology.

The MAGM Series MMIC PAs are specifically tailored for mainstream 5G basestation architectures, meeting and surpassing the power density and thermal requirements of 64-element massive MIMO antenna arrays, with a pathway to exceeding the performance of LDMOS technology, at scaled volume level production cost structures and supply capacities that can’t be achieved with competing GaN-on-SiC technology. Designed with MACOM proprietary wideband circuit topology, the PAs meet the stringent 5G TDD linearity requirement using off the shelf digital-pre-distortion (“DPD”) systems. Compared to earlier generation multichip-format GaN-on-Si modules, costs are further lowered through a reduction in packaging and design complexity. Leveraging this ideal performance and cost with the capacity scale manufacturing afforded by MACOM’s partnership with ST Microelectronics, MACOM’s GaN-on-Si solutions are expected to be able to significantly improve customers’ time to market.

MACOM’s MAGM-103436-040AOP is the first product in the MAGM Series that is now sampling to qualified customers, with production availability scheduled for 2H 2018. For more information about MACOM’s solutions for 5G wireless infrastructure, click here.

At Mobile World Congress 2018, Wireless Infrastructure experts from MACOM are talking about the MAGM Power Amplifiers and other enabling technologies for 5G. Stop by their booth to learn more about their 5G solutions.
