ADMV8420CHIPS-SX

Overview

The ADMV8420CHIPS-SX is a monolithic microwave integrated circuit (MMIC) tunable band-pass filter operating from 10 GHz to 22.8 GHz. It features a user-selectable passband frequency controlled by an analog voltage applied to the VFCTL pin, sweeping the center frequency between 10.5 GHz and 21 GHz. The device offers a 3 dB bandwidth of approximately 20% and provides wideband rejection of at least 30 dB. Key electrical specifications include a typical insertion loss of 5 dB, an input third-order intercept point (IP3) of 26 dBm, and an amplitude settling time of 200 ns. The component is supplied as a bare die in a 7-pad configuration.

Feature Summary

• Monolithic design providing minimal microphonics compared to cavity tuned filters
• Symmetrical architecture allowing interchangeable use of RF input and output pads
• Analog control interface for dynamic adjustment of center frequency
• RoHS-compliant bare die construction

Applications

• Airport scanners
• Test and measurement equipment
• Military radar and electronic warfare systems
• Very small aperture terminal (VSAT) communications

Procurement Notes

Verify that the specific ordering suffix matches the required package option. Confirm the temperature range aligns with system requirements. Ensure handling procedures account for the bare die nature of the component. Check for RoHS compliance status if mandated by project standards. Validate supply chain sources against official manufacturer documentation.

Selection Notes

Select this component when a compact alternative to switched filter banks is required. Consider the 200 ns settling time for applications requiring rapid frequency hopping. Evaluate the 5 dB insertion loss against system link budget constraints. Ensure the control voltage range of 0 V to 15 V is compatible with available bias supplies. Verify substrate compatibility for wire bonding and die attachment.

Part Context

The ADMV8420CHIPS-SX belongs to the Analog Devices ADMV8420 family of tunable band-pass filters. It shares core functional specifications with the standard ADMV8420CHIPS variant but differs in its specific packaging or reel configuration indicated by the suffix. Both variants operate within the same -40°C to +85°C temperature range and utilize the identical 7-pad bare die outline.

Replacement Considerations

The ADMV8420CHIPS is a direct equivalent part number within the same product family.
