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.
