A schematic of the Evaluation Board is shown in Figure 4.Circuit Design ConsiderationsThe following design considerations are general in nature and must be followed regardless of final use or configuration:∙Paths to ground should be made as short as possible.∙If the transceiver TXRX port has DC present, use a capacitor to block this voltage from reaching the RFX2401C.∙The ground pad of the RFX2401C has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Because the circuit board acts as the heat sink, it must shunt as much heat as possible from the device.Multiple vias to the grounding layer are e thermal vias to assure efficient heat dissipation. ∙Locate the bypass capacitors as close as possible to the ground pad. Use two ground vias.∙The VDD (pin 14) is an optional VDD pin, internally connected to pin 16.∙The N/C pins 1, 7, 12, and 15 may be left open or connected to GND.∙If the antenna circuits have DC present, use a capacitor to block this voltage from reaching the RFX2401C.NOTE: A poor connection between the ground pad and ground increases junction temperature (T J), which reduces the lifeof the device..J4Figure 3.
