Precision, Matched, Baseband Filter ICs Outperform Discrete
Implementations вЂ“ Design Note 476

Introduction
In digital communication systems, baseband signals must
be band-limited in the transmitter or the receiver. Although
the bulk of baseband signal shaping and analysis is accomplished using digital signal processing (DSP), analog
п¬Ѓltering is used in a number of places along the signal
chain. For instance analog п¬Ѓlters reduce the imaging of a
digital-to-analog converter (DAC), п¬Ѓlter out the high frequency noise of an RF demodulator or reduce the aliasing
inputs of an analog-to-digital converter (ADC).
Typically, 3G communication systems (CDMA, GSM,
UMTS or WiMax) feature a baseband channel bandwidth
of 1.25MHz to over 20MHz. In this frequency range, discrete analog п¬ЃltersвЂ”those constructed with high speed
op amps, resistors and capacitorsвЂ”are sensitive to PCB
layout parasitics, component tolerances and mismatches.
The pitfalls of using discrete components can be avoided
by using integrated, pin-conп¬Ѓgurable, precision analog
п¬Ѓlter ICs, such as the LTC6601-1/-2 and the LTC6605-7/
-10/-14. The LTC6601-x is a single 2nd order lowpass п¬Ѓlter
and the LTC6605-x is a dual, matched п¬Ѓlter.
