32 Lead 5x5 mm SMT Package 25 mm2 Functional Diagram 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 …
