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
is recommended for maximum output
power (0dBm). Lower load impedance (for instance 50
) can be obtained by fitting a
simple matching network.

Table 21 Crystal specification of the nRF2401A
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
L
=12pF is OK, but it is possible to use up to 16pF.
Specifying a lower value of crystal parallel equivalent capacitance, C
0
will also work,
but this can increase the price of the crystal itself. Typically C
0
=1.5pF at a crystal
specified for C
0max
=7.0pF.
