The LTC® 6602 is a dual , programmabl e bandpass f il ter
and dif f erential driver. The sel ectivity of the LTC6602 is
ideal f or f il tering baseband tag signal s in R FI D systems.
The LTC® 6603 is a dual , programmabl e l ow pass f il ter f or
communications receivers and transmitters in TD-SCDM A,
W CDM A, CDM A2000, U M TS
DC1304A-A or -- - B board has tw o pairs of SM A connectors
f or dif f erential inputs and tw o pairs of SM A connectors f or
dif f erential outputs. The dif f erential inputs can be AC cou-
pl ed or DC coupl ed. O n board j umpers provide control of an
LTC6602 or an LTC6603. The j umper control settings are:
serial or paral l el control , internal or external cl ock, gain and
bandw idth control and input AC or DC coupl ing. An on
board mul ti-turn potentiometer sets the val ue of the R BI AS
resistor that sets the I C pow er suppl y current and cl ock
f requency. PCB turrets provide f or board connections to an
SPI master f or a serial control of I C gain and bandw idth.
