The HMC891ALP5E is a monolithic microwave integrated circuit (MMIC) band-pass filter that features a user-selectable pass band frequency. The 3 dB filter bandwidth is approximately 9% and the 20 dB filter bandwidth is approximately 23%. The center frequency (fCENTER) can be varied between 1.95 GHz and 3.4 GHz by applying an analog tune voltage between 0 V and 14 V.

This tunable filter can be used as a smaller alternative to physically large switched filter banks and cavity tuned filters.

The HMC891ALP5E has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications.

Applications

  • Testing and measurement equipment
  • Military radar and electronic warfare/electronic counter measure (ECM)

Product Detail

All RF traces are routed on Layer 1 (primary side) and the remaining three layers are ground planes that provide a solid ground for RF transmission lines. The top dielectric material is Rogers 4350, which offers low loss performance. The prepreg material in Layer 2 attaches the Isola 370HR core layer with copper traces layers above and below the core layer. Both prepreg material and the Isola 370HR core layer are used to achieve the required board finish thickness.
