ADMV8502ACCZ

Overview

The ADMV8502ACCZ is a digitally tunable, octave-band band-pass filter from Analog Devices. It operates within a frequency range of 90 MHz to 225 MHz. The device features a typical 3dB bandwidth of 9% and an insertion loss of 3.5 dB. It utilizes a 40-lead BFLGA package with an exposed pad. The component supports SPI interface control for tuning adjustments.

Feature Summary

• Digitally tunable octave-band band-pass filtering capability
• Single-chip replacement for discrete filter banks
• SPI interface for digital control

Applications

• Wireless infrastructure systems
• Software-defined radio platforms
• Test and measurement equipment

Procurement Notes

Verify the specific suffix (ACCZ) against official Analog Devices documentation to confirm pinout and packaging details. Confirm current availability status as supply constraints may apply. Ensure ESD protection protocols are followed during handling due to the LGA package type.

Selection Notes

Select this component when a digitally controlled, wide-tuning-range band-pass filter is required in the VHF/UHF spectrum. Compare insertion loss and bandwidth specifications against system requirements. Verify compatibility with existing SPI control logic and power supply voltages before integration.

Part Context

This part belongs to the ADMV85xx series of tunable RF filters. It serves as a compact alternative to mechanical or varactor-based discrete filter assemblies. The series offers integrated tuning solutions for modern RF front-end designs requiring agility and reduced board space.

Replacement Considerations

Direct substitutes include other models from the ADMV85xx family, such as the ADMV8505ACCZ, which covers adjacent frequency ranges. Verify that the substitute part meets the specific center frequency and bandwidth requirements of the application.
