Features
- Three modules
- QRP Labs Receiver 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
- Can be used with a Switched Bandpass filter board for multiband operation
- QRP Labs Polyphase filter
- Polyphase network plug-in module kit which cancels the unwanted sideband and produces a single sideband (SSB) output
- QRP Labs Receiver Module
- Band Pass Filter and Polyphase filter mount on Receiver Module
- The receiver requires a local oscillator (LO) input at 4x the receive frequency
- The receiver module is sized 80 x 37mm
