About this document
40m Direct Conversion Receiver Circuit by Shrivlsi Ram is a document available to read on EtoBox.
This document summarizes a 40-meter direct conversion receiver circuit that can receive amateur radio signals in both CW and SSB modes. The circuit uses three n-channel FETs, with the first acting as an antenna/RF amplifier and product detector, and the second and third forming a variable frequency oscillator. The VFO output is mixed with the incoming signal to produce an audio beat note. An audio amplifier built around an IC amplifies the output for listening on a small speaker. The receiver can operate fr
