Appendix G: Receiver Amplifier Gain Values
The receive path has many amplifiers and their gain can be configured also.
There are 4 parameters:
RF LNA High Compression Mode: 0 or 1 (default is 1)
RF LNA Gain:
1 dB, 7 dB, or 13 dB (for 13 dB, RF LNA High
Compression Mode must be 0) (default is 1 dB)
IF LNA Gain:
24 dB, 18 dB, 12 dB, or 6 dB (default is 24 dB)
AGC Gain:
-12 dB, -6 dB, 0 dB, 6 dB (default is -6 dB)
If one has to read tags that are far away, or tags that are heavily blocked, then increasing the RF
LNA Gain may help.
However, if tags can be very close to the antenna, then one may need to check if the increased
LNA Gain cause saturation of the LNA. To check, just put a tag at a distance that is closest
possible to the antenna during the site’s specific business scenario, and see if that tag can be
read properly.
