Filter T uning
The MAX2101 integrates two 5th-order Butterworth low-
pass filters for anti-alias filtering of the baseband sig-
nal. One filter exists for each of the I and Q channels.
The filters’ cutoff frequency is set by driving the FTUNE
pins, pin 77 (I channel) and pin 4 (Q channel). The user
sets the I/Q channel filters independently. Figure 6
shows a typical transfer curve of a filter’s cutoff fre-
quency versus FTUNE voltage.
The MAX2101’s anti-aliasing filtering function provides
superior channel-to-channel matching compared to a
discrete implementation. The filters are realized using a
gyrator topology, which inherently has a strong temper-
ature dependency. The temperature dependency of the
filters must be compensated to achieve a consistent fil-
ter response over ambient temperature. This compen-
sation is easily summed with the user-supplied filter
tune signal, with the techniques discussed for both cur-
rent-drive and voltage-drive implementations later in
this section. Figure 7 shows a typical characteristic of
the FTUNE signal required to provide a constant filter
cutoff frequency over temperature.
