Dual-mode TD-LTE/TD-SCDMA RF Transceiver

Expressions of Interest Contact our expert Print  

ASTRI's TD-LTE/TD-SCDMA dual mode RFIC transceiver is designed for User Equipment (UE). It supports triple spectrum bands in TD-LTE and TD-SCDMA standards:

  • 2300 - 2400 MHz band in TD-LTE
  • 2010 - 2025 MHz and1880 - 1920 MHz bands in TD-SCDMA

Targeted at the huge opportunities offered by the China market, ASTRI's RFIC is posed to improve China's TD industry chain at high end and reduce IC import cost.

Benefits to Customers

  • UE automatically upgraded to enable extremely high speed of LTE wherever there is a hotspot
  • UE operates in TD-SCDMA 3G network
