1.0 GHz to 1.9 GHz Tunable Band-Pass Filter

The HMC890ALP5E is a monolithic microwave integrated circuit (MMIC), band-pass filter that features a user selectable pass-band frequency. The 3 dB filter bandwidth is approximately 10%. The ≥20 dB filter bandwidth is approximately 30%. The center frequency can vary between 1.0 GHz and 1.9 GHz by applying an analog tuning voltage between 0 V and 14 V. This tunable filter can be used as a much smaller alternative to physically large switched filter banks and cavity tuned filters.

The HMC890ALP5E has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications.
