LTC6603: Dual, Matched, High Frequency Bandpass/Lowpass Filters.
The LTC6603 is a dual, matched, programmable bandpass or lowpass filter and differential driver. The selectivity of the LTC6603, combined with its phase matching and dynamic range, make it ideal for filtering in RFID systems. With two degree phase matching between channels, the LTC6603 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.
