Band pass filter is tunable over 9 to 90 GHz
The HMC897 band pass tunable filter chip is ideal for pre-selection in advanced communications systems, military radar, EW/ECM, SATCOM, space, industrial and medical systems. The center frequency of the chip is adjustable from 9 to 19 GHz by applying an analog tune voltage between 0 and 14 V with a tuning speed of 200 ns.
The filter exhibits excellent microphonic immunity due to the monolithic design, and provides a dynamically adjustable solution that makes it highly beneficial for use in advanced communications applications. It also provides a 3-dB filter bandwidth of approximately 18%, while the 20-dB filter bandwidth is approximately 35%.
Return loss is typically better than 10 dB across the operating frequency and wideband rejection is at least 30 dB out to 40 GHz. Residual phase noise is as low as –160 dBc/Hz at 100-kHz offset. For applications which require a surface mount compatible solution, this same filter is available in a RoHS-compliant 4 x 4-mm QFN SMT package as the HMC897LP4E.
