Notes
1. 100% AM modulation (ASK); available power from generator into a 50 load.
2. With external matching network, to transform the impedance to 50 Ω.
3. f = 10 kHz; available power from generator into a 50 load.
4. Measured at the RF input connector of the test board into a 50 load; fi(RF) = 25 MHz to 1 GHz.
5. The data frequency range can be varied by changing C30 to C32 (see Figs 9 and 10) to match other bit rates.
Data frequency determined by data slicer application.
6. ton = 50 ms; toff = 138 ms; P = Psens + 3 dB.
7. The given turn-on time is only valid during strobing by pin PWD; if the IC is strobed on and off by the supply voltage
the turn-on time will be longer.
8. LC tank circuit (L60, C60) tuned to maximum phase slope.
9. GPMA is typically 6 dB lower when measured in the application, because of the load of the ceramic filter.
