ADVANCED COMMUNICATIONS & SENSING
In FSK mode, the unwanted signal is unmodulated (as described in the EN 300-220 V2.1.1).Co-Channel
Rejection (CCR, Offset = 0kHz) is positive due to the DC cancellation process of the zero-IF architecture
In OOK mode, the polyphase filter efficiency is limited, thus limiting the adjacent channel rejection at 2xFo
distance.
