Features and Benefits
- Amplitude settling time: 200 ns
- Excellent wideband rejection: ≥30 dB
- Single chip replacement for mechanically tuned designs
- 32-lead 5 mm × 5 mm RoHS compliant LFCSP package
The HMC890ALP5E 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 10%. The ≥20 dB filter bandwidth is approximately 30%. The center frequency can vary between 1.0 GHz and 1.9 GHz by applying an analog tuning voltage between 0 V and 14 V. This tunable filter can be used as a much smaller alternative to physically large switched filter banks and cavity tuned filters.
The HMC890ALP5E 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 all other remaining layers are ground planes that provide a solid ground for RF transmission lines. The top dielectric material is Rogers 4350, offering low loss performance. The prepreg material in the middle sticks core layers together, which includes an Isola 370HR layer with copper traces above and below. Both the prepreg material and the Isola 370HR core layer are used to achieve required board finish thickness.
The circuit board used in the application uses radio frequency (RF) circuit design techniques. Signal lines must have 50 Ω impedance while the package ground leads and exposed paddle must be connected directly to the ground plane. Use a sufficient number of via holes to connect the top and bottom ground planes. The EV1HMC890ALP5 evaluation board is available from Analog Devices, Inc. upon request.
Tools & Simulations
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.
