5
6 The LTC6602 is a dual, matched, programmable bandpass or lowpass filter
7 and differential driver. The selectivity of the LTC6602, combined with its
8 phase matching and dynamic range, make it ideal for filtering in RFID
9 systems. With two degree phase matching between channels, the LTC6602 can
10 be used in applications requiring highly matched filters, such as
11 transceiver I and Q channels. Gain programmability, and the fully
12 differential inputs and outputs, simplify implementation in most systems.
