5 PCB layout description
This section describes critical layout details to be carefully considered during a PCB
design. The PCB design requires an optimal solution for the following topics:
? Create a solid ground plane for the antenna. The PCB has to be considered as a
part of the antenna; it interacts with the radiated electromagnetic wave
? Isolate digital noise from the antenna and the radio transceiver to achieve
optimum range and RF performance
? Isolate digital noise from the 16MHz reference crystal to achieve optimum
transmitter and receiver performance
? Reduce any kind of spurious emissions below the limits set by the individual
regulatory organizations
The REB232ED PCB design further demonstrates a low-cost, two-layer PCB solution
without the need of an inner ground plane.
The drawing in Figure 5-1 shows critical sections using numbered captions. Each
caption number has its own subsection below with detailed information.
