Key Specs or Limitations:

Misc Notes:

  1. This stage not used in direct-conversion receiver
  2. If an active mixer is used (like the NE602/SE612), an output amplifier will probably not be required; if a passive (diode ring) mixer is used, an AF output amplifier will be required. An amplifier, if used, should have low-pass roll-off to minimize hiss and eliminate IF feedthrough to the output.
