GENERAL DESCRIPTION

The ADMV8513 is an RF band-pass filter that features a digitally

selectable frequency of operation. The filter center frequency (fCEN-

TER) can be adjusted from 520 MHz to 1300 MHz, using an 8-bit

value (256 states) that incorporates a patent pending interpolation

technique.

The typical 3 dB bandwidth is 8.5% with narrow-band and wide-

band options and adjustability is ±2%. Insertion loss is typically 5.5

dB, and the 20 dB rejection is 17% away from fCENTER, which is

ideally suited for minimizing system interferers.

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.
