Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended.
Sensitivity is defined as the average signal level measured at the input necessary to achieve 10
defined as a return-to-zero (RZ) waveform with 50% average duty cycle (Manchester encoded data). The RF input is assumed to be matched
into 50 .
Spurious reverse isolation represents the spurious components which appear on the RF input pin (ANT) measured into 50 with an input RF
matching network. Parameter guaranteed by device characterization, not production tested.
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
background noise is appreciably higher than the thermal noise. Background noise refers to other interfering signals, such as FM radio stations,
pagers, etc.
A better indicator of achievable 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.
