Functional Diagram
The HMC890LP5E is a MMIC band pass lter which
features a user selectable passband frequency.
The 3 dB lter bandwidth is approximately 11%. The
20 dB lter bandwidth is approximately 33%. The
center frequency can be varied between 1 and 2
GHz by applying an analog tune voltage between 0
and 14V. This tunable lter can be used as a much
smaller alternative to physically large switched lter
banks and cavity tuned lters. The HMC890LP5E has
excellent microphonics due to the monolithic design,
and provides a dynamically adjustable solution in
advanced communications applications.
