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.
