General Description
The HMC895LP4E is a MMIC band pass filter which
features a user selectable passband frequency. The
3 dB filter bandwidth is approximately 10%. The 20
dB filter bandwidth is approximately 22%. The center
frequency can be varied between 6.8 and 12.6
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 HMC895LP4E has
excellent microphonics due to the monolithic design,
and provides a dynamically adjustable solution in
advanced communications applications.
