Features and Benefits
- Amplitude settling time: 200 ns
- Re-entry rejection (wideband rejection): ≥30 dB
- Single-chip replacement for mechanically tuned designs
- RoHs compliant, 32-lead, 5 mm x 5 mm LFCSP package
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.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
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.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
