GENERAL DESCRIPTION

The ADMV8526 is an RF band-pass filter that features a digitally

value (256 states) that incorporates a patent pending interpolation

technique.

The typical 3 dB bandwidth is 9% and adjustability is ±2%. Insertion

loss is typically 4 dB, and the 20 dB rejection is 16% away from

This tunable filter can be used as a smaller alternative to large

switched filter banks and discrete component-based tunable filters,

and this device provides a dynamically adjustable solution in ad-

vanced communications applications.
