5
6 The LTC®6603 is a dual, matched, programmable lowpass
7 filter for communications receivers and transmitters. The
8 selectivity of the LTC6603, combined with its linear phase,
9 phase matching and dynamic range, make it suitable for
10 filtering in many communications systems. With 1.5°
11 phase matching between channels, the LTC6603 can be
12 used in applications requiring pairs of matched filters,
13 such as transceiver I and Q channels. Furthermore, the
14 differential inputs and outputs provide a simple interface
15 for most communications systems.
