ADMV8416ACPZ

Overview

The ADMV8416ACPZ is a monolithic microwave integrated circuit (MMIC) tunable band-pass filter from Analog Devices Inc. It features a user-selectable passband frequency with a usable corner frequency range spanning 6.3 GHz to 18 GHz. The device operates in two bands controlled by the VCTL pin: high band (12.6 GHz to 16.8 GHz center frequency) and low band (6.8 GHz to 12 GHz center frequency). The 3 dB bandwidth is approximately 15% of the center frequency, while the 20 dB bandwidth is 37%. Wideband rejection is maintained at ≥20 dB on both sides. Key electrical parameters include an insertion loss of 8 dB, return loss of 8.5 dB (high band), input IP3 of 38 dBm (high band), and amplitude settling time of 200 ns. It requires dual supplies of +5 V and -5 V.

Feature Summary

• Single-chip implementation providing a compact alternative to large switched filter banks and cavity-tuned filters.
• User-selectable passband frequency via analog tuning voltage for dynamically adjustable filtering solutions.
• Excellent microphonics performance resulting from its monolithic design architecture.

Applications

• Test and measurement equipment
• Military radar and electronic warfare systems
• Video satellite communications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure proper ESD handling protocols are followed during storage and assembly due to the device's sensitivity rating. Review the latest datasheet revision for any updates to absolute maximum ratings or interface schematics before finalizing procurement orders.

Selection Notes

Select this component when a wide tuning range covering 6.3 GHz to 18 GHz is required in a single package. Choose the high-band mode for frequencies above 12.6 GHz and low-band mode below 12 GHz using the VCTL control voltage. Consider the 8 dB insertion loss and 38 dBm IP3 specifications for system link budget calculations. Ensure the design supports the necessary ±5 V supply rails and provides adequate thermal grounding for the exposed pad.

Part Context

The ADMV8416 belongs to Analog Devices' family of tunable MMIC band-pass filters designed for RF front-end applications. It replaces bulky mechanical tuning mechanisms with a solid-state solution. The device integrates the tuning mechanism and filtering elements into a 40-lead LFCSP package, facilitating integration into modern compact communication systems requiring agile frequency selection capabilities.

Replacement Considerations

The ADMV8416-EVALZ is the official evaluation board for testing this component. No direct cross-manufacturer substitutes are confirmed in the provided documentation. Designers should verify pin compatibility and electrical specifications if considering alternative tunable filters from other manufacturers.
