NOTES
1. All signal voltages are RMS unless stated otherwise.
2. Level of out of band blocking signal to cause 1dB compression of in band wanted signal.
3. Measured with unmodulated blocking signals at 60 and 120kHz.
4. These filter characteristics are for the 60kHz bandpass filter. This provides all the filtering in FM mode. There is additional filtering
in l/Q mode provided by the baseband low pass filters. Details are shown in Figure 4.
5. Extrapolate linearly between 22kHz-38kHz, 82kHz-98kHz.
6. The input and output signal ranges are the maximum available. For example if the input signal is 2V pk-pk then the programmed
gain must only be 0dB.
7. Noise relative to full scale signal.
