TIDA-00068

Basestation Transceiver with DPD Feedback Path

TIDA-00068

Design files

Overview

The design is for a small cell base station development platform.  It provides two real receive paths, two complex transmit paths, and a shared real feedback path.  This design has macro basestation performance, but with small cell base station footprint.  The current design handles up to 20MHz of bandwidth.

Features
  • 2 Complex Tx Paths
  • 2 Shared Real FB Path
  • 2 Real Rx Paths
  • 30.72M Reference Input
  • Clocking: CDCE72010
  • Control: USB/Serial Interface
  • 6V Power Supply
Communications equipment

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
