GENERAL DESCRIPTION

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

selectable frequency of operation. The filter center frequency (fCENTER)

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 wideband

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 advanced

communications applications.
