Functional Diagram
General Description
The HMC897LP4E 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 HMC897LP4E has
excellent microphonics due to the monolithic design,
and provides a dynamically adjustable solution in
advanced communications applications.

[1] Optimum residual phase noise performance requires the use of a low noise driver circuit.
[2] Tuning speed is dependent on driver circuit. Data measured with a high speed op-amp driver and includes driver slew rate delay.
