LTE UE Reference

The LTE UE Reference design by Lekha is a Category 2 UE. Using this Reference Design, OEMs can build LTE UEs for different form factors like an Outdoor type, Vehicle mount, Man-pack or Handset.  LTE UE from Lekha supports most of the significant & mandatory features specified by 3GPP, for Release 9 versions of the standard. Lekha’s UE solution adopts a modular design.

The LTE UE reference design has interworked with multiple eNodeBs and T&M equipment.  The UE solution is backed by few patents filed by Lekha with respect to PSS and SSS synchronization and Turbo Decoder.

Current design supports up to 1 transmit and 2 receiver antenna ports. There are two AD9361 Radios provisioned to support L3 relay mode operation and multi band carrier aggregation for future enhancements

Key features supported are

  • 3GPP Release 9 compliant
  • Category 2
  • 2×2 DL MIMO
  • 1 Tx and 2 Rx
  • 1.4, 3, 5,10 and 20 MHz bandwidth support
  • Maximum RF out power is 33dBm
  • Band 28 (support for any other LTE band on demand)
  • FDD mode supported
  • All 3GPP FDD bands are supported at low power RF

Major application for the UE reference design is setting up LTE network in non-LTE bands, high power UE requirements and custom LTE network for high security communications.
