5G modem chip supports mmWave and sub-6-GHz 5G networks
Fabless semiconductor company MediaTek has announced a 5G modem that combines mmWave and sub-6 GHz 5G technologies onto a single chip.

The M80 5G modem supports ultra-fast speeds on both non-standalone (NSA) and standalone (SA) architectures, with a peak rate of 7.67 Gbps in the downlink and 3.76 Gbps in the uplink. The M80, says the company, also supports dual 5G SIM, dual 5G NSA and SA networks, and dual Voice over New Radio (VoNR) for more reliable connectivity.

"As 5G rollouts accelerate, mmWave is becoming increasingly important, especially in the U.S.," says JC Hsu, Corporate Vice President and General Manager of MediaTek's Wireless Communications Business Unit. "MediaTek's new 5G modem integrates support for both sub-6 GHz and mmWave networks to address this opportunity and give device makers more flexibility. To advance users' 5G experiences, the new modem supports the latest global cellular standards and specifications and it packs MediaTek's signature power savings technologies along with ultra-fast speeds."

The company says its 5G modems are ideal for a range of devices, including smartphones, PCs, Mi-Fi hotspots, broadband customer premise equipment (CPE), industrial IoT applications, and more. The M80 offers operators around the world support for a full range of radio access technologies:

  • 3GPP Release 16 standard
  • Sub-6 GHz and mmWave dual connectivity and carrier aggregation
  • 5G NR (FR1) with more than two carrier aggregation
  • 5G mmWave (FR2) up to 8CC
  • 5G carrier aggregation with Mixed Duplex (TDD + FDD)
  • Dynamic spectrum sharing (DSS) ready

The M80 integrates the company's 5G UltraSave technologies, which, says the company, improve on the single-chip design to provide another layer of extensive power-saving enhancements. MediaTek's UltraSave Network Environment Detection and UltraSave OTA Content Awareness technologies dynamically adjust power configuration and operating frequency based on the network environment.

The M80 also integrates MediaTek's Dynamic Bandwidth Part (BWP) technology, which is designed to optimize bandwidth use to accommodate light or heavy data throughput requests. Additionally, with the M80's Connected Mode DRX (C-DRX) technology the modem will regularly remain powered in connected standby even when there is no data
