Selection guidance needed (Analog RF programmatic delay lines)

Hello All,

 

I have a question about what hardware from Analog Devices I could use to delay an RF signal in a programmatic manner.

 

The input signal x(t) has bandwidth 100MHz, and is centered around a carrier frequency of 2.4GHz.

 

I want N outputs (N=8, say), such that output 'i' is x(t - Ti), where Ti is the delay imposed at the 'i'th output. The maximum value of Ti is 10ns.

 

These delays Ti are independent, and I should be able to programmatically (say, through USB, or a serial interface) set these values. Any pointers on which product might be a match for me?

 

Thanks in advance for your help! I have posted a little block diagram if a clarification is needed.

 

Best,

Aditya
