General Description
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.

Typical Applications
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
