The ADMV8505 from Analog Devices is a Band-Pass Filter (BPF) with a digitally-selectable center frequency from 225 to 520 MHz. It has a 3 dB bandwidth of 9% with a passband insertion loss of 4.5 dB and provides a rejection of 20 dB. This 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. It is available in an LGA package that measures 10 x 10 mm and requires DC supplies of +3.3/-2.5 V. The filter is ideal for use in land mobile radios, test and measurement equipment, military radars and electronic warfare and electronic countermeasures, satellite communications and industrial and medical equipment.
