LTC6603
Dual Adjustable
Lowpass Filter
FEATURES DESCRIPTION n The LTCВ®6603 is a dual, matched, programmable lowpass
п¬Ѓlter for communications receivers and transmitters. The
selectivity of the LTC6603, combined with its linear phase,
phase matching and dynamic range, make it suitable for
п¬Ѓltering in many communications systems. With 1.5В°
phase matching between channels, the LTC6603 can be
used in applications requiring pairs of matched п¬Ѓlters,
such as transceiver I and Q channels. Furthermore, the
differential inputs and outputs provide a simple interface
for most communications systems. n Guaranteed Phase and Gain Matching Specs
