PRODUCT SPECIFICATION
nRF2401 Single Chip 2.4 GHz Radio Transceiver
Antenna output
The ANT1 & ANT2 output pins provide a balanced RF output to the antenna. The
pins must have a DC path to VDD, either via a RF choke or via the center point in a
dipole antenna. The load impedance seen between the ANT1/ANT2 outputs should be
in the range 200-700 . A load of 100 +j175
power (0dBm). Lower load impedance (for instance 50
simple matching network.
Output Power adjustment
Crystal Specification
Tolerance includes initially accuracy and tolerance over temperature and aging.
To achieve a crystal oscillator solution with low power consumption and fast start-up
time, it is recommended to specify the crystal with a low value of crystal load
capacitance. Specifying C
Specifying a lower value of crystal parallel equivalent capacitance, C
but this can increase the price of the crystal itself. Typically C
specified for C
