RECEIVER CHARACTERISTICS (280MHz)
Receiver Characteristics (280MHz) are guaranteed over the following range of operating conditions unless otherwise stated.
Characteristics are not tested but are guaranteed by characterisation test or design. All measurements made using the
characterisation circuit Fig. 5. See Application Note AN137 for details of test method.
TAMB = 210°C to 155°C, VCC1 = 1·04V to 2·0V, VCC2 = 2·3V to 3·2V, VCC1,VCC220·8V, carrier frequency = 280MHz,
BER = 1 in 30, AFC open loop. LNA gain set such that an RF signal of273dBm at the LNA input, offset from the LO
by 4kHz, gives a typical IF signal level of 300mV p-p at TPI and TPQ. LNA noise figure,2dB

NOTE
The mark:space amplitude acceptance is the maximum amplitude ratio which can occur (for example due to Simulcast conditions) with 2400bps,
using a POCSAG decoder with R14 = 120kΩ to achieve an 80% call rate and the lower amplitude set at a sensitivity of 120dB. the maxima and
minima of the amplitude modulation correspond to the positive and negative (or vice versa) frequency shifts of the FSK modulation.
