HMC900LP5E 50 MHz Dual Baseband Programmable Low Pass Filter
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 to 50 MHz, and when calibrated, is accurate to ±2.5% of the desired bandwidth. It includes a filter bypass option with a bandwidth of 100 MHz, while retaining gain and common mode settings. Housed in a compact 5x5mm SMT QFN package, the HMC900LP5E requires minimal external components and provides a low cost alternative to more complicated switched discrete filter architectures. Filter calibration for the HMC900LP5E is accomplished 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.
