DESCRIPTION
Dual Matched, High
Frequency Bandpass/Lowpass Filters
TheLTC6602isadual,matched,programmablebandpass
orlowpassfilteranddifferentialdriver.Theselectivityofthe
LTC6602, combined with its phase matching and dynamic
range, make it ideal for filtering in RFID systems. With two
degreephasematchingbetweenchannels,theLTC6602can
be used in applications requiring highly matched filters,
such as transceiver I and Q channels. Gain programmabil-
ity, 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.
