GENERAL DESCRIPTION

The HMC881A is a monolithic microwave integrated circuit

(MMIC) low-pass filter that features a user-selectable cutoff

frequency. The cutoff frequency can be varied from 2.4 GHz to

4 GHz by applying a single analog tuning voltage between 0 V

and 14 V. This low-pass filter provides a low 3 dB insertion loss,

16.5 dB return loss, and 1.35 × f_3dBstopband 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 HMC881A 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 5 mm ×

5 mm LFCSP package.
