Analog Devices HMC882A Monolithic Microwave Integrated Circuit is a low-pass filter that highlights a user-selectable cutoff frequency (f3dB). The cutoff frequency is varied between 3.95GHz to 6.9GHz by applying a single analog tuning voltage between 0V and 14V. This low-pass filter offers a low 3dB insertion loss, 13dB return loss, and >20dB stopband attenuation at 1.28xf3dB GHz.
This tunable filter can be used as a smaller option to physically large switched filter banks and cavity tuned filters. The device has superior microphonics due to the monolithic design and low residual phase noise of -165dBc/Hz. The device offers a dynamically adjustable solution in advanced communications applications. The low-pass tunable filter is supplied in a RoHS compliant, 5mm x 5mm LFCSP package.
Suitable applications include testing and measurement equipment; defence radar and ECMs; satellite communication and space; and industrial and medical equipment.
