All values are in dBm unless stated. The values shown in red exceed the regulatory
requirements.
The matched balun filter (0868BM15C0001 passes all the harmonic requirements. The IL has
increased since the dual band version (0896BM15A0001) but this is understandable
considering that the attenuation is increased for the harmonics and a notch has been
included to eliminate the fundamental – 169 MHz spur.
