Linear Technology DC1304A-A Quick Start Manual

DESCRIPTION
Demonstration Circuit DC1304A features two programmable
filter ICs, the LTC6602 dual, matched, bandpass filter and the
LTC6603, dual, matched, lowpass filter.
The DC1304A- - - - A A A A is for The DC1304A is for an LTC6602 and an LTC6602 and
The DC1304A The DC1304A is for is for an LTC6602 and an LTC6602 and
The DC1304A The DC1304A The DC1304A- - - - B is for The DC1304A B is for B is for B is for an LTC6603. an LTC6603. an LTC6603. an LTC6603.
The LTC®6602 is a dual, programmable bandpass filter and
differential driver. The selectivity of the LTC6602 is ideal for
filtering baseband tag signals in RFID systems.
The LTC®6603 is a dual, programmable lowpass filter for
communications receivers and transmitters in TD-SCDMA,
WCDMA, CDMA2000, UMTS
A DC1304A-A or -- - B board has two pairs of SMA connectors
for differential inputs and two pairs of SMA connectors for
differential outputs. The differential inputs can be AC coupled
or DC coupled. On board jumpers provide control of an
LTC6602 or an LTC6603. The jumper control settings are:
serial or parallel control, internal or external clock, gain and
bandwidth control and input Ac or DC coupling. An on board
multi-turn potentiometer sets the value of the RBIAS resistor
that sets the IC power supply current and clock frequency.
PCB turrets provide for board connections to an SPI master
for a serial control of IC gain and bandwidth.
