9.1 Receiver
RF signals often suffer from reflections along the path of propagation. These reflected signals arrive at the receiver antenna with
different phases or time delays. The different phases of the reflected signals causes the signal strength at the receiver to vary. This
variation can be large enough to cause the receiver to miss information. The AMIS-52100 sums the signals from the dual receiver
channels inside the data detection circuits. This reduces the effect of the multipath reflections. The receivers in the AMIS-52100 require
that the frequency be trimmed, the receiver oscillator frequency be tuned, the data rate filters be selected, and a signal threshold set as
shown in Table 20.
Table 21 lists some characteristic parameters for the receivers. Figure 7 shows a typical received data waveform.
