2.4 Output Connectors

There are six output connectors (SMA) on the EVM.

  • LNA OUT/ BPF_INPUT (J12): LNA output (LNA o/p) comes to this connector. There is also provision to disconnect the LNA output from this connector (by removing R25) and connect it to the on board Bandpass filter provision by shorting R37
  • LOG output (J9): LOG detector output (LOG o/p) comes to this connector.
  • BUF_OUT (J5): Non inverting Buffer output
  • INV BUF OUT (J7): Inverted buffer output.
  • FREQ DETECT (J4): frequency detect output. If there is a need to drive large capacitor from freq detect, it is advisable to remove R36 and populate R32, R33, C23, C25 and U3 to digitally buffer frequency detect output.
  • EXT AMP OUT (J11): the output from the LOG detector can be amplified or buffered using an external amplifier U2. Output of which can be taken from this connector.
