The ADMV8502 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.APPLICATIONSLand mobile radiosTest and measurement equipmentMilitary radars and electronic warfare and electronic countermeasuresSatellite communicationsIndustrial and medical equipment
