Notes:

1. BER = 1e-3, data rate = 2Kb/s.

2. Use AM 99% with square wave modulation (if limited by capabilities of signal generator).

3. Data rate selection affects choice of component values for data filter, peak detector and slicer.

4. AGC attack and decay currents are around 15

µA and 1.5µA.

5. AGC threshold depends on the gain setting and matching of LNA.
