ADMV8505 Series

The ADMV85051is an RF band-pass filter that features a digitally selectable frequency of operation. The filter center frequency (fCENTER) 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 dB bandwidth is 9%, and adjustability is ±2%. Insertion loss is typically 4.5 dB, and the 20 dB rejection is 19% away from the fCENTER, which is ideally suited for minimizing system interferers.The ADMV8505 tunable filter can be used as a smaller alternative to large switched filter banks and discrete component-based tunable filters, providing a dynamically adjustable solution in advanced communications applications.ApplicationsLand mobile radiosTest and measurement equipmentMilitary radars and electronic warfare and electronic countermeasuresSatellite communicationsIndustrial and medical equipment
