HMC895LP4Ev01.0911

FILTER - TUNABLE, BAND PASS SMT6.8 - 12.6 GHz

Functional Diagram

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.

Typical Applications Features

Evaluation PCB

The circuit board used in the application should use RF circuit design techniques. Signal lines should have 50 Ohms impedance while the package ground leads and exposed paddle should be con-nected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
