Re: Recommendation for high sample rate receiver?

[Mike]

The device in question is to replace an existing RF-to-baseband
component of a geographically distributed signal collection system. 
Each receiving station samples the 6 MHz passband, detects a signal and
estimates a time-of-arrival, then sends it on to a central facility that
performs the multilateration calculations.  The existing TOA codebase
(and other decoders) expects 2 ns samples.

Thanks!
