LTC6603IUF#PBF

LTC6603 is a dual, matched, programmable lowpass filter for communications receivers and transmitter. The selectivity of the device, combined with its linear phase, phase matching and dynamic range, make it suitable for filtering in many communications systems. With 1.5° phase matching between channels, this device can be used in applications requiring pairs of matched filters, such as transceiver I and Q channels. Furthermore, the differential inputs and outputs provide a simple interface for most communications systems. The sampled data filter does not require an external clock yet its cut-off frequency can be set with a single external resistor with an accuracy of 3.5% or better. It is used in applications such as small/low cost base stations: IDEN, PHS, TD-SCDMA, CDMA2000, WCDMA, UMTS, low cost repeaters, radio links, and modems, 802.11x receivers, JTRS.
