For years, the direct-conversion radio architecture has been analyzed and a few successful implementations targeting low-performance systems have made it to production. Using a combination of analog ...

Direct conversion receivers are pretty simple, so that leaves us with only four modules for oscillator, bandpass filter, mixer, and audio amplifier.

Zero IF receivers have had limited success in high performance systems, such as wireless basestations, due primarily to their limited dynamic range.

Direct conversion receivers are popular among ham radio operators and others who build radios. Suppose you want to listen to a signal at 7.1 MHz. With a direct conversion receiver, you’d tune… ...
