General Description
The HMC900LP5E is ideal for various modulation
systems:
• Baseband ltering before A/D or after D/A converters
for point-to-point xed wireless or base station
transceivers (GSM/GPRS, WCDMA & TD-SCDMA)
• Integrated direct conversion receiver (DCR) when
mated with mixer and VGA
• Software dened radio applications
• Anti-aliasing and reconstruction lters
• Test and measurement equipment

The HMC900LP5E is a 6th order, programmable
bandwidth, fully calibrated, dual low pass lter. 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
lter 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 lter 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 exibility allowing the user “set and
forget” parameters like gain and bandwidth setting.
Matched lter 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
at passband and minimal group delay variation.
