GENERAL DESCRIPTION

The ADMV85021 is an RF band-pass filter that features a digitally

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

can be adjusted from 90 MHz to 225 MHz, using an 8-bit value

(256 states) that incorporates a patented calibration technique.

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

loss is typically 3.5 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 the ADMV8502 provides a dynamically adjustable solution in

advanced communications applications.
