General Description
The HMC897 is a MMIC band pass filter which features
a user selectable passband frequency. The 3 dB filter
bandwidth is approximately 18%. The 20 dB filter
bandwidth is approximately 35%. The center frequency
can be varied between 9 and 19 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 HMC897 has excellent microphonics due
to the monolithic design, and provides a dynamically
adjustable solution in advanced communications
applications.
