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.Applications Baseband Filtering for A/D or D/A Converters  Point-to-Point, Fixed Wireless & Cellular Base Station Transceivers Integrated Direct Conversion Receiver (DCR)  Software Defined Radio Applications Test & Measurement Equipment

The HMC1044LP3E is a programmable bandwidth LPF (Low Pass Filter) targeted at all applications that use quadrature modulators and/or demodulators. The HMC1044LP3E filters out LO harmonics and ensures little or no LO contribution to modulator sideband rejection or demodulator image rejection performance.Although targeted at LO filtering applications, the HMC1044LP3E can be used to filter all RF harmonics such as the ones generated by amplifiers.The HMC1044LP3E offers a choice of 16 programmable bands, optimized for high and low cellular bands ranging from 1 to 3 GHz, making the a truly wideband part compatible with wideband PLLs with Integrated VCOs and wideband quadrature modulators and demodulators. It enables wideband multi-standard, multi-carrier designs that are field configurable on-the-fly for each individual application.The HMC1044LP3E is packaged in a compact 3x3 mm QFN leadless package.APPLICATIONS Filtering LO Harmonics to Reduce Modulator Sideband Rejection & Demodulator Image Rejection Amplifier Harmonic Filtering RF Filtering

The HMC891LP5E is a MMIC band pass filter which features a user selectable passband frequency. The 3 dB filter bandwidth is approximately 9%. The 20 dB filter bandwidth is approximately 27%. The center frequency can be varied between 2 and 3.9 GHz by applying an analog tune voltage between 0 and 14V. This tunable filter can be used as a much smaller alternative to physically large switched filter banks and cavity tuned filters. The HMC891LP5E has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications.Applications Test & Measurement Equipment Military RADAR & EW/ECM SATCOM & Space R&D Laboratories
