Analog Devices Inc. ADMV8526 Digitally Tunable Filters
Analog Devices Inc. ADMV8526 Digitally Tunable Filters are RF band-pass filters that feature a digitally selectable frequency of operation. This device features a 1.25GHz to 2.60GHz adjustable FCENTER frequency range and uses an 8-bit value (256 states) that incorporates a patent-pending interpolation technique. These tunable filters can be used as a smaller alternative to large switched filter banks and discrete component-based tunable filters. Typical applications of tunable filters include land mobile radios, test and measurement equipment, military radars, electronic warfare, electronic countermeasures, satellite communications, and industrial and medical equipment.
Features
- Digitally tunable, octave and band-pass tuning
- 9% ± 2% 3dB bandwidth
- 16% away from fCENTER rejection (20dB)
- Single-chip replacement for discrete filter banks
- 10mm × 10mm × 1.99mm compact LGA package
Applications
- Land mobile radios
- Test and measurement equipment
- Military radars and electronic warfare and electronic countermeasures
- Satellite communications
- Industrial and medical equipment
