Features
- This high performance receiver module uses a Quadrature Sampling Detector (QSD), also known as a Tayloe Detector
- The mixer is arranged as a double-balanced mixer for maximum performance
- The receiver board has a socket for the standard QRP Labs Band Pass Filter kit
- There is a transmit/receive switch onboard. Low noise LM4562 op-amps are used in instrumentation amplifier configuration to provide excellent common mode noise rejection
- The receiver requires a local oscillator (LO) input at 4x the receive frequency
- 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
- For those situations where a PC has only a mono input (many PCs are like this, particularly laptops), there is an optional polyphase network plug-in module kit which cancels the unwanted sideband and produces a single sideband (SSB) output.
- The module is sized 80 x 37mm
