- Single-chip implementation
- 24-lead, 4 mm × 4 mm, RoHS-compliant LFCSP
The ADMV8420 is a monolithic microwave integrated circuit (MMIC), tunable band-pass filter that features a user-selectable pass band frequency. The 3 dB filter bandwidth is approximately 20%, and the 20 dB filter bandwidth is approximately 40%. Additionally, the center frequency (fCENTER) varies between 11.1 GHz to 19.6 GHz by applying a center frequency control voltage between 0 V to 15 V. The usable pass band corner frequencies (fCORNER) span from 10 GHz to 21.7 GHz. This tunable filter is a smaller alternative to switched filter banks and cavity tuned filters. The ADMV8420 has minimal 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 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 Layer 2 attaches the Isola 370HR with copper traces layers above and below together. Both the prepreg material and the Isola 370HR core layer are used to achieve the required board finish thickness.
The circuit board used in the application uses RF circuit design techniques. Signal lines must have 50 Ω impedance while the package ground leads and exposed pad must be connected directly to the ground plane. Use a sufficient number of via holes to connect the top and bottom ground planes. The ADMV8420-EVALZ evaluation board is available from Analog Devices, Inc., upon request.
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.
