5G-NTN Modem IP for Satellite
User Terminals

Ceva-PentaG-NTN

PentaG-NTN is a 5G Non Terrestrial Network (NTN) modem IP subsystem optimized for satellite user terminals operating in LEO and MEO constellations.

 

Built on Ceva’s third-generation PentaG platform, it addresses the unique technical challenges of non-terrestrial networks while enabling rapid integration into satellite SoCs.

 

Delivered as a fully validated modem subsystem, PentaG-NTN enables satellite-native innovators and semiconductor companies to deploy standards-based 5G-NTN connectivity without the cost and complexity of developing a cellular baseband modem from the ground up.

 

The Solution

PentaG NTN is a fully validated 5G NTN Modem IP, delivered as an integrated, plug‑and‑play baseband modem subsystem.
