TIDA-01442

Direct RF-Sampling Radar Receiver for L-, S-, C-, and X-Band Using ADC12DJ3200 Reference Design

TIDA-01442

Design files

Overview

The TIDA-01442 reference design utilizes the ADC12DJ3200 evaluation module (EVM) to demonstrate a direct RF-sampling receiver for a radar operating in HF, VHF, UHF, L-, S-, C-, and part of X-band. The wide analog input bandwidth and high sampling rate (6.4 GSPS) of the analog-to-digital converter (ADC) provides multiband coverage with a single or dual ADC. The direct RF-sampling capabilities of the ADC reduces the component count by eliminating several down-conversion stages, thereby reducing overall system complexity.

Features
  • High-input-frequency capability of ADC allows RF sampling of signals from L-band to X-band
  • Max sample rate of 6.4 GSPS in single-channel (interleaved) mode and 3.2 GSPS in dual-channel mode
  • Four independent NCOs per DDC allow fast frequency hopping among bands
  • Clocking solution optimized for low jitter and JESD204B operation

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