采用 ADC12DJ3200 且适用于 L、S、C 和 X 频带的直接射频采样雷达接收器参考设计
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.
