Functional Diagram
General Description
The HMC882LP5E is a MMIC low pass filter which
features a user selectable cutoff frequency. The
cutoff frequency can be varied from 4.5 to 7.6 GHz
by applying a single analog tuning voltage between
0 and 14V. This low pass filter provides a low 2.9 dB
insertion loss, 10 dB return loss and 1.23 x ƒcutoff
stopband attenuation of >20 dB. This tunable filter can
be used as a much smaller alternative to physically
large switched filter banks and cavity tuned filters.
The HMC882LP5E has excellent microphonics due
to the monolithic design, and provides a dynamically
adjustable solution in advanced communications
applications. The low pass tunable filter is packaged
in a RoHS compliant 5x5mm QFN leadless package.

[1] ƒcutoff defined as the point at which the insertion loss is 3 dB below the minimum passband insertion loss.
[2] Optimum residual phase noise performance requires the use of a low noise driver circuit.
[3]Tuning speed is dependent on driver circuit. Data measured with a high speed op-amp driver and includes driver slew rate delay.
