Note 1: 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 ohms.
Note 2: Spurious reverse isolation represents the spurious components which appear on the RF input (ANT)
pin measured into 50 ohms with an input RF matching network.
Note 3: 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 he 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.
Note 4: Exceeding the absolute maximum ratings may damage the device.
Note 5: The device is not guaranteed to function outside its operating ratings.
