Sensitivity is defined as the average signal level measured at the input necessary to achieve 10e-2 Bit Error Rate (BER). The
input signal is defined as a return-to-zero (RZ) waveform with 50% average duty cycle at a data rate of 2400bps. The RF input
is assumed to be matched into 50 .
Spurious reverse isolation represents the spurious components which appear on the RF input (ANT) pin measured into 50
with an input RF matching network.
Sensitivity, a commonly specified Receiver parameter, provides an indication of the Receiver’s input referred noise, generally
input thermal noise. However, it is possible for a more sensitive receiver to exhibit range performance no better than that of a
less sensitive receiver, if the “ether” noise is appreciably higher than the thermal noise. “Ether” noise refers to other interfering
“noise” sources, such as FM radio stations, pagers, etc.
A better indicator of receiver range performance is usually given by its Selectivity, often stated as Intermediate Frequency (IF)
or Radio Frequency (RF) bandwidth, depending on receiver topology. Selectivity is a measure of the rejection by the receiver
of “ether” noise. More selective receivers will almost invariably provide better range. Only when the receiver selectivity is so
high that most of the noise on the receiver input is actually thermal will the receiver demonstrate sensitivity-limited
performance.
