1. GENERAL
PCB layout files for single ended RF I/O layout has been made for Nordic Semiconductors’s
nRF2401A Single Chip 2.4 GHz RF Transceiver [1].
The Zip archive file includes a file named readme.wri that must be read before importing the
files into PCB editors.
The described layout should be manufactured on standard 1.6mm double-sided FR4 printed
circuit board (PCB).
2. RF LAYOUT FOR nRF2401A
The RF layout includes all necessary circuitry to design the radio part of a short-range
communication system based on nRF2401A. All digital control signals are available at the
perimeter of the RF layout to be connected to the digital part of customer applications.
Supply voltage and GND are also available at the perimeter of the RF layout. The supply
voltage for the RF part of the application circuit should be filtered separately from the supply
voltages of any digital circuitry. Star routing is strictly recommended from the voltage supply
source to the RF and digital or other parts of the application circuitry.
