[Discuss-gnuradio] Downconversion to 45 MHz Intermediate

Hi experts

My work requires the downconversion from 437MHz to 45MHz of the received signal.  

I am told some SDR device with IF at 45.05MHz output are already in market. Do you know any? Could you please refer to me? I know about "AOR 2003" but too expensive for student work.

Is there any?

Thank You
