We have read out from UG570 that the RX LPF is a third order butterworth low pass filter. In theory, butterworth low pass filter response is 20dB/decade/pole. We understand that RX LPF suppression is 60dB for a frequency component of 10 times of the corner frequency. As an example, if we set the corner frequency to 30MHz, RX LPF suppress 300MHz 60dB. Is that right?
