Four-Channel Digitally Tunable RF-Filter IC Spans 0.5 to 9 GHz

Analog Devices introduces the ADMV8809, a digitally tunable RF-filter IC that spans 0.5 to 9 GHz, offering flexibility in RF system design. The MMIC integrates four high/low-pass filters with independently controlled center frequencies. The device's programmability allows for adjusting cutoff frequencies and is controlled via an SPI port. Analog Devices provides an evaluation board, EVAL-ADMV8809, to facilitate setup and performance assessment of the RF filter IC. The device's datasheet includes detailed characteristic curves, performance tables, and design-in suggestions for optimal RF performance.
