11.26 Factory Calibration
Microchip
device-to-device variation in standby current, internal
timing and sensitivity, as well as channel-to-channel
sensitivity variation.
11.27 De-Q’ing of Antenna Circuit
When the transponder is close to the base station, the
transponder coil may develop coil voltage higher than
V
detects the strong near field signal through the AGC
control, and de-Q’ing the antenna circuit to reduce the
input signal amplitude.

11.28 Battery Back-up and Batteryless
The device supports both battery back-up and
batteryless operation by the addition of external
components, allowing the device to be partially or
completely powered from the field.
Figure 11-8 shows an example of the external circuit for
