Hi Jeffrey, I'm reading a book called "RF and Digital Signal Processing for Software-Defined Radio - Elsevier Newnes - 2009". It seems to have a good coverage of the theory. On Jun 18, 2010, at 10:36 AM, Jeffrey Lambert wrote: > I would recommend cha

Hello, An RF Front-end can take many forms, depending upon the application. For use with the USRP or similar hardware, a direct-conversion approach is probably adequate. This type of front-end typically consists of low noise amplifier (LNA), mixer, and perhaps a baseband/IF amplifier or auto

Hi, I would like to design a custom board based on the Spartan-3AN FPGA, based on the Spartan-3AN FPGA Starter Kit, but would like to build my own RF front-end. http://www.analog.com/en/rfif-components/rxtx-subsystems/products/index.html If I look at the AD9874 IF-to-Bits RX subsystem
