It has a 3 dB bandwidth of 9% and supports 8-bit (256 states) tuning using an interpolation technique. This filter can handle an RF input power of 24 dBm and has an insertion loss of 4 dB. It can be used as a smaller alternative to large, switched filter banks and discrete component-based tunable filters. The filter requires a DC supply of 3.3 V and consumes 125 μA of current.
The ADMV8526 is available in an LGA package that measures 10.00 x 10.00 x 1.99 mm and is ideal for use in land mobile radios, test and measurement equipment, military radars, and electronic warfare and electronic counter-measures, satellite communications, industrial and medical equipment applications.
