Analog Devices Inc. HMC890 Tunable Band-Pass Filters

Analog Devices Inc. HMC890 Tunable Band-Pass Filters are Monolithic Microwave Integrated Circuits (MMICs) that feature a user selectable pass-band frequency. The center frequency can vary between 1GHz and 1.9GHz by applying an analog tuning voltage between 0V and 14V. The HMC890 band-pass filters can be used as a much smaller alternative to physically large switched filter banks and cavity tuned filters. These monolithic designed filters provide a dynamically adjustable solution in advanced communication applications. Some of the applications include test and measurement equipment, military RADAR and electronic warfare, satellite communications, industrial, and medical equipment.
