The ADMV8052 is a RF filter that features a digitally selectable frequency of operation. The device has three band-pass filters (BPFs) that span across three specified bands from 30 MHz to 520 MHz.

The center frequency (f_CENTER) of operation can be adjusted using an 8-bit value (256 states) that incorporates a patented interpolation technique. The typical bandwidth (3 dB) is 9% and adjustability is ±2%. The insertion loss is typically less than 4.5 dB and the rejection is 20 dB at 25% away from the f_CENTER, which is ideally suited for minimizing system harmonics. Additionally, the flexible architecture incorporates a bypass configuration with a low insertion loss of <1 dB.

This tunable filter can be used as a smaller alternative to large switched filter banks and cavity tuned filters, and this device provides a dynamically adjustable solution in advanced communications applications.
