GENERAL DESCRIPTION
The ADMV85051 is an RF band-pass filter that features a digitally selectable frequency of operation. The filter center frequency (f CENTER) can be adjusted from 225 MHz to 520 MHz using an 8-bit value (256 states) that incorporates a patented calibration technique. The typical 3 d B bandwidth is 9%, and adjustability is ±2%. Insertion loss is typically 4.5 d B, and the 20 d B rejection is 19% away from the f CENTER, which is ideally suited for minimizing system interferers. The ADMV8505 tunable filter can be used as a smaller alternative to...
