POWER SUPPLY CONSIDERATIONS
BOARD LAYOUT CONSIDERATIONS
Figure 8: Recommended PCB layout
The user must provide a clean source of power
to the module to ensure proper operation.
Power-supply noise will manifest itself as AM
and FM noise and can significantly affect
transceiver performance. Providing a clean
power supply for the module should be a high
design priority.
The TR-XXX-SC-PA incorporates an on-board
Low-Dropout Regulator allowing the module to
operate over an input voltage range of 2.7 to 13
volts DC. The module’s power-supply line should have bypass capacitors
configured as shown in figure 7. Actual capacitor values will vary depending on
noise conditions.
If you are at all familiar with RF devices, you may be concerned about
specialized layout requirements. Fortunately, because of the care taken by
Linx in the layout of the module’s PCB, integrating a TR-XXX-SC-PA
transceiver into your design is very straightforward. By adhering carefully to a
few basic design and layout rules, you can enjoy a trouble-free path to RF
success.
Figure 8 shows the suggested PCB footprint for the TR-XXX-SC-PA.
A groundplane (as large as possible) should be placed directly under the TR-XXX-
SC-PA. This groundplane can also be critical to the performance of your antenna.
The SC-PA should, as much as reasonably possible, be isolated from all other
components on your PCB. Specifically, high-frequency circuitry such as crystal
oscillators should be kept as far away as possible from the module.
