ADMV8420ACPZ-R5

Overview

The ADMV8420ACPZ-R5 is a monolithic microwave integrated circuit (MMIC) tunable band-pass filter operating from 10 GHz to 21.7 GHz. It features a user-selectable passband frequency controlled by an analog voltage applied to the VFCTL pin, ranging from 0 V to 15 V. The center frequency (fCENTER) varies between 11.1 GHz and 19.6 GHz. The device exhibits a 3 dB bandwidth of approximately 20% and a 20 dB bandwidth of approximately 40%. Key electrical specifications include a typical insertion loss of 5 dB, return loss of 8.5 dB, and input third-order intercept point (IP3) of 31 dBm. It is housed in a 24-lead, 4 mm × 4 mm RoHS-compliant LFCSP package.

Feature Summary

• Single-chip MMIC implementation providing a compact alternative to switched filter banks and cavity tuned filters.
• Analog voltage-controlled tuning capability allowing dynamic adjustment of the center frequency across a wide band.
• Minimal microphonics due to monolithic design, ensuring stability in advanced communication applications.

Applications

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

Procurement Notes

Verify the specific ordering suffix -R5 indicates tape and reel packaging when sourcing components. Confirm that the procurement channel provides valid manufacturer traceability for Analog Devices Inc. products. Ensure the received units match the RoHS-compliant specification and operate within the stated temperature range of −40°C to +85°C. Check for moisture sensitivity level (MSL) handling requirements upon delivery.

Selection Notes

Select this component when a dynamically adjustable band-pass filter is required in the V-band frequency range. Consider the 200 ns amplitude settling time and phase sensitivity characteristics for system timing constraints. Evaluate the control voltage interface requirements, noting the need for low baseband noise to minimize additive phase noise. Ensure the application can accommodate the 50 Ω dc-coupled RF interfaces without external biasing.

Part Context

The ADMV8420ACPZ-R5 belongs to the ADMV8420 family of tunable band-pass filters manufactured by Analog Devices Inc. It shares core functional specifications with the standard ADMV8420ACPZ variant but differs in packaging format. The device is part of a series designed to replace larger, less flexible filtering solutions in high-frequency applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify compatibility with existing board layouts if considering alternatives, as pin configurations and thermal requirements may differ significantly across different filter families.
