ADMV8526ACCZ

ADMV8526ACCZ is an RF band-pass filter that features a digitally selectable frequency of operation. The filter centre frequency (fCENTER) can be adjusted from 1.25GHz to 2.60GHz, using an 8bit value (256 states) that incorporates a patent-pending interpolation technique. The typical 3dB bandwidth is 9% and adjustability is ±2%. Insertion loss is typically 4dB, and the 20dB rejection is 16% 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. It is also used in applications such as land mobile radios, test and measurement equipment, military radars and electronic warfare and electronic countermeasures, satellite communications, industrial and medical equipment.
