RFX2401C Datasheet, PDF (6/10 Pages) Skyworks Solutions Inc. – CMOS 2.4GHZ ZIGBEE/ISM TRANSMIT/RECEIVE RFeIC

APPLICATION CIRCUIT GUIDELINES
Central Ground Pad
Use thermal vias to
Assure efficient heat
dissipation
RFX2401C
Production Data Sheet
Locate bypass capacitor as
Close to the ground pad as
Possible. Use 2 ground vias.
RF Port is at DC GND potential!
If the Transceiver TXRX port has DC present,
use a capacitor to block this voltage from
reaching the RFX2401C.
