homemade gps receiver

  • My Thesis: A 144MHz FM/SSB receiver

    The receiver is a double-superhet for SSB and a tribble-superhet for FM The front-end is the same for FM and SSB After per-amplification the received signal is mixed down to the first intermediate frequency (IF) of 48MHz A variable gain amplifier can adjust the signal level based on the control signal from the automatic gain control (AGC) circuit The signal is then further mixed down to
