World’s First RISC-V Multi-Mode LTE Chipset Unveiled for 450MHz Networks

GCT Semiconductor, a pioneer in wireless technology, has made a groundbreaking advancement by developing the world's first multi-mode LTE chipset designed specifically for the 450MHz spectrum. This innovative chipset, named GDM7243SL, features two cutting-edge RISC-V cores that set it apart from existing solutions in the market.

The GDM7243SL is a highly integrated chipset that supports a wide range of LTE modes, including Cat 4, Cat 1bis, Cat-M1, Cat NB1/NB2, and even non-terrestrial networks (NTN) for satellite connections. What makes this chipset truly exceptional is its ability to operate in frequencies as low as 450MHz and 380MHz, making it ideal for use in challenging environments where traditional networks struggle to provide reliable connectivity.

Equipped with dual receive paths, low-band dual transmitters, and 2x2 MIMO diversity, the GDM7243SL ensures robust connectivity even in the most demanding conditions, such as underground facilities or remote forest areas. This chipset's high power capabilities make it a reliable choice for applications that require uninterrupted communication.

One of the key features of the GDM7243SL is its dual-core RISC-V design, which includes integrated RAM and optional Flash memory. This design allows customers to develop fully integrated devices without the need for an external processor, streamlining the development process and reducing overall costs.

With a monolithic baseband and radio that covers frequencies from 380MHz to 3.8GHz, the GDM7243SL offers a versatile solution for a wide range of applications. Supported by a 400MHz RISC-V core for RF control and another core for operating systems like Linux and OpenWRT, this chipset is well-equipped to meet the diverse needs of IoT devices and other connected systems.
