external (antenna) filter, as implemented
in the application circuit in

must be used and tailored to each
individual design to reduce out-of-band
spurious emission levels.
Spurious emissions can be measured as
EIRP values according to EN 300 220.
The antenna (SMAFF-433 and SMAFF-
Spurious emission,
868 from R.W. Badland) plays a part in
radiated CW
attenuating the spurious emissions.

If the output power is increased using an
external PA, a filter must be used to
attenuate spurs below 862 MHz when
operating in the 868 MHz frequency
band in Europe. Application Note

( SWRA057 ) presents and
discusses a solution that reduces the TX
mode spurious emission close to 862
