ADMV8505ACCZ

Overview

The ADMV8505ACCZ is a digitally tunable band-pass filter from Analog Devices, operating within the 225 MHz to 520 MHz frequency range. It functions as an active signal conditioning component designed for precise RF filtering applications. The device supports a supply voltage of 3.3 V and operates reliably across a temperature range of -40°C to +85°C. Housed in a compact LGA-40 package with solder termination, it offers a center frequency tuning capability essential for modern communication systems requiring agile spectral selection.

Feature Summary

• Digitally controlled center frequency tuning across a wide RF spectrum
• Active band-pass filtering architecture for signal conditioning
• Compact surface-mount LGA-40 packaging for space-constrained designs

Applications

• Wireless infrastructure base stations
• Software-defined radio (SDR) front ends
• Test and measurement instrumentation
• Military and aerospace communication systems

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm lot codes and date stamps against current manufacturing records. Ensure storage conditions comply with moisture sensitivity level requirements prior to reflow soldering. Request original manufacturer documentation to validate specifications and compliance status before integration into production lines.

Selection Notes

Select this component when digital tuning agility is required within the 225 MHz to 520 MHz band. Consider the LGA-40 footprint for PCB layout compatibility. Evaluate thermal management needs given the operational temperature range. Compare insertion loss and selectivity metrics against system requirements to ensure adequate signal integrity in high-interference environments.

Part Context

Part of the ADMV85xx series of tunable filters, the ADMV8505ACCZ complements other models like the ADMV8502 and ADMV8513 by covering specific mid-range RF frequencies. It shares the same LGA-40 form factor and digital control interface, allowing for modular design approaches across different frequency bands in complex RF transceiver architectures.

Replacement Considerations

Direct substitutes include ADMV8505ACCZ-R7. Verify pinout and electrical characteristics match exactly. Alternative models such as ADMV8502 or ADMV8513 cover different frequency ranges and are not direct replacements unless system bandwidth allows.
