Overview

The TSW40RF82EVM reference design provides a platform to interface the DAC38RF82 with a high-performance modulator - the TRF370417EVM. The TRF370417EVM can modulate wideband signals at up to 6 GHz as would be typical for a microwave backhaul application. The TRF370417 device may be substituted for a suitable higher-frequency device. Minimal modification is required to interface the digital-to-analog converter (DAC) with the modulator. This design provides the method to interface the TSW40RF82EVM with the TRF370417EVM.

Features
  • High-bandwidth zero-intermediate frequency (zero-IF) transmitter solution
  • DAC solution with RF-sampling speed up to 8 GSPS
  • Wideband modulation with TRF370417EVM up to 6 GHz
  • Modulator can be interchanged to achieve higher RF frequencies
  • Modulation error ratio (MER) over 40 dB throughout 5-GHz frequency band
