Features

  • Three modules
    • QRP Labs Radio Module
      • High performance Receiver module uses a Quadrature Sampling Detector (QSD), also known as a Tayloe Detector
      • FST3253 Mixer is arranged as a double-balanced mixer for maximum performance
      • Mute during transmit switch circuit
      • Low noise LM4562 op-amps are used in instrumentation amplifier configuration to provide excellent common mode noise rejection
      • The audio output of the module is isolated using two 600:600-ohm transformers to reduce or eliminate the ground loop problems which can easily occur in SDR systems
      • The module is designed to directly drive a stereo input sound-card
      • Receiver board has a socket for the standard QRP Labs Band Pass Filter kit which can be routed to an external bandpass filter switch card
    • QRP Labs Band Pass Filter
    • QRP Labs Polyphase filter
      • Polyphase network plug-in module kit which cancels the unwanted sideband and produces a single sideband (SSB) output
  • The receiver requires a local oscillator (LO) input at 4x the receive frequency
  • The receiver module is sized 80 x 37mm
