Power Requirements
RF Power Output
The Micro supports separate read and write power level which are command adjustable
via the MercuryAPI. Power levels must be between:
– Minimum RF Power = 0 dBm
– Maximum RF Power = +30 dBm
Note
Maximum power may have to be reduced to meet regulatory limits, which
specify the combined effect of the module, antenna, cable and enclosure
shielding of the integrated product.
Power Supply Ripple
The following are the minimum requirements to avoid module damage and to insure
performance and regulatory specifications are met. Certain local regulatory specifications
may require tighter specifications.
3.5 to 5.25VDC
Less than 25 mV pk-pk ripple all frequencies,
Less than 11 mV pk-pk ripple for frequencies less than 100 kHz,
No spectral spike greater than 5 mV pk-pk in any 1 kHz band.
