ASTRI TD-LTE/TD-SCDMA dual-mode RF transceiver chip is designed for User Equipment (UE). It supports frequency bands in TD-LTE and TD-SCDMA standards:

• 2300 - 2400 MHz and 2570 - 2620 MHz bands for TD-LTE
• 2010 - 2025 MHz and 1880 - 1920 MHz bands for TD-SCDMA.

This RF transceiver targets at huge Mainland market to improve their high-end TD industry chain. UE can operate in TD-SCDMA 3G network and automatically upgrades to extremely high-speed LTE wherever there is a hotspot.
