RX Filters
The combination of the external filter (an LC ladder filter typically) with the integrated lowpass filter pro-
vides:
– echo reduction to improve dynamic range
– DMT sidelobe and out of band (anti-aliasing) attenuation.
– Anti alias filter (60 dB rejection @ image freq.)
ATU-R-RX filters
The integrated filter characteristics are shown in table 6.
ATU-C-RX Filter
This filter is the same as the one used for ATU-R_TX.
Linearity of RX
Linearity of the RX analog path is defined by the IM3 product of two sinusoidal signals with frequencies f1
and f2 and each with 0.5 Vpd amplitude (total _1 Vpd) at the output of the RX-AGC amplifier (i.e: before
the ADC) for the case of minimal AGC setting.
