There will be spurious signals at n/2·crystal oscillator
frequency (n is an integer number). RF frequencies at
n/2·crystal oscillator frequency should therefore not be
used (e.g. 2405, 2418, 2444, 2457, 2470 and 2483 MHz
when using a 26 MHz crystal). Please refer to the
CC2550
Errata Note for more details.
