Dual-Wideband RF-to-Digital Receiver Design

Other Parts Discussed in Thread: TSW1265EVM, ADS4249

Hi TI,

TSW1265EVM this part no can i digitize the analog signal input to the board with following spec...

1. IF: 60MHz

2. Input max limit : +12dBm

3. Dynamic range : 100dB


The range should be 100 DB to meet the requirement, kindly suggest ...

  • Hello Yashwitha,

    The TSW1265EVM consisted of a front end RF to IF mixer (SKY part number or MAX part number) with P1dB of typically 13.3dBm. THe RF range is 700MHz to 1000MHz and IF range is 40Mhz to 300MHz. I would say the IF and input max limit may meet your need.

    However, the ADC is the ADS4249 with SNR of ~72.2dBFS and SFDR of 79dBFS. This may not meet your need of 100dBc of dynamic range.

    As always, you should look at the line up of the signal chain based on the TSW1265 schematic and perform your own analysis to see if this meet your system needs.
