The 3 dB filter bandwidth is approximately 18%. The 20 dB filter bandwidth is approximately 35%. The center frequency can be varied between 19 and 38 GHz by applying an analog tune voltage between 0 and 14V. This tunable filter can be used as a much smaller alternative to physically large switched filter banks and cavity tuned filters. The HMC899 has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications. Typical Applications Features General Description FILTER - TUNABLE, BAND PASS 19 - 38 GHz The HMC899 is ideal for: • Test & Measurement Equipment • Military RADAR & EW/ECM • SATCOM & Space • Industrial & Medical Equipment Fast Tuning Response Excellent Wideband Rejection Single Chip Replacement for Mechanically Tuned Designs Small Size: 2.5 x 1.2 x 0.10 mm Electrical Specifications, T A = +25 °C Parameter Min.
