MOTOROLA ANALOG IC DEVICE DATA
SYSTEM PERFORMANCE DATA
RSSI
In Figure 22, the RSSI versus RF Input Level shows the
linear response of RSSI over a 65 dB range but it has
extended capability over 80 dB from –80 dBm to +10 dBm.
The RSSI is measured in the application circuit (Figure 12) in
which a SAW filter is used before the mixer; thus, the overall
sensitivity is compromised for the sake of selectivity. The
curves are shown for three filters having different
bandwidths:
1) LCR Filter with 2.3 MHz 3.0 dB BW (Circuit and
Component Placement is shown in Figure 12)
2) Series–Parallel Ceramic Filter with 650 kHz 3.0 dB BW
(Murata Part # KMFC–545)
3) Ceramic Filter with 280 kHz 3.0 dB BW.

SINAD Performance
Figure 24 shows a test setup for a narrowband
demodulator output response in which a C–message filter
and an active de–emphasis filter is used following the
demodulator. The input is matched using a 1:4 impedance
transformer. The SINAD performance is shown in Figure 25
with no preamp and in Figure 26 with a preamp (Preamp –
Figure 16). The 12 dB SINAD sensitivity is –101 dBm with no
preamp and –113 dBm with the preamp.
