HMC899

v00.0911

Functional Diagram

The HMC899 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 19 and 38

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 HMC899 has

excellent microphonics due to the monolithic design,

and provides a dynamically adjustable solution in

advanced communications applications.
