2 PDR8000 HARDWARE FORM FACTORS

2.1 PDR8000 S
UITCASE
PDR8000 suitcase form factor is typically a self-contained device but is easily modified to utilize
an alternate duplexer and/or a transmit power Booster Pack when required. Different RF
hardware combinations are supported, using accessible internal and external connection points
to enable the desired configuration. Note that the PDR8000 internal duplexer is easily
accessible and swappable. The cavity housing the internal duplexer is easily accessed by
removing a panel of the PDR8000 faceplate via four thumbscrews.

Figure 3: Internal Duplexer Cavity

The need to field-swap a duplexer depends upon the range of RF frequencies being used on
the different channels configured in a PDR8000. Duplexers have a defined Bandpass, meaning
that if widely diverse RF frequencies are used within the same RF band, it may be necessary to
install a different duplexer into the PDR when traversing frequencies (changing channels) to
another portion of the RF band. Duplexers typically cover a broad band of frequencies, but if
the frequencies on different channels are outside of the tuning parameters of the duplexer, it is
necessary to substitute a different duplexer when the channel is changed.
Several different duplexers are available, in different RF bands, and factory-tuned to customer
specified frequencies. Those available for purchase with the PDR8000 are listed below.
Customer supplied duplexers (installed inside the duplexer cavity, or outside of the PDR8000
case may also be used).
