General Description

The HMC900lP5e is ideal for various modulation

systems:

• Baseband filtering before a/D or after D/a converters

for point-to-point fixed wireless or base station

transceivers (gsM/gPRs, WCDMa & TD-sCDMa)

• Integrated direct conversion receiver (DCR) when

mated with mixer and Vga

• software defined radio applications

• anti-aliasing and reconstruction filters

• Test and measurement equipment

Read/Write serial Port Interface (sPI)

The HMC900lP5e is a 6th order, programmable

bandwidth, fully calibrated, dual low pass filter. It

features 0 or 10 dB input gain setting and supports

arbitrary bandwidths from 3.5 MHz to 50 MHz,

and when calibrated, is accurate to +/-2.5% of the

desired bandwidth. It includes a 100 MHz bandwidth

filter bypass option while retaining gain setting and

common mode control.

Housed in a compact 5x5 mm sMT QFN package,

the

HMC900lP5e

requires

minimal

exter-

nal components and provides a low cost alternative to

more complicated switched discrete filter architectures.

The integrated aDC driver and externally controlled

common mode output level further simplify system

implementations.

Filter calibration for the HMC900lP5e is accomp-

lished with any reference clock rate from 20 to 80

MHz. One time programmable (OTP) memory offers

unsurpassed flexibility allowing the user “set and

forget” parameters like gain and bandwidth setting.

Matched filter paths provide excellent quadrature

balance, making the HMC900lP5e ideal for I/Q

communications applications.

The 6th order Butterworth transfer function delivers

superior stop band rejection while maintaining both a

flat passband and minimal group delay variation.
