Description

The LTC6602 is a dual, matched, programmable bandpass or lowpass filter and differential driver. The selectivity of the LTC6602, combined with its phase matching and dynamic range, make it ideal for filtering in RFID systems. With two degree phase matching between channels, the LTC6602 can be used in applications requiring highly matched filters, such as transceiver I and Q channels. Gain programmability, and the fully differential inputs and outputs, simplify implementation in most systems. Both channels of the LTC6602 consist of a programmable lowpass and highpass filter. For bandpass functionality, the lowpass filters are programmed for the upper cutoff frequency. For lowpass functionality, the highpass filters can be bypassed. The filter cutoff frequencies can be set with a guaranteed accuracy of 3% with the use of a single resistor. Alternatively, the filter cutoff frequencies can be controlled with an external clock. The LTC6602 operates on a single 2.7V to 3.6V supply and features a low power shutdown mode.Applications Multiprotocol RFID Readers: EPC-GEN2, ISD and IPX IDEN, PHS, GSM Basestations Repeaters, Radio Links, and Modems Wireless Telemetry JTRS
