ADMV8526ACCZ-R7

Overview

The ADMV8526ACCZ-R7 is a digitally tunable band-pass filter operating from 1.25 GHz to 2.60 GHz. It features a typical 3 dB bandwidth of 9% with ±2% adjustability and an insertion loss of 4 dB. The device utilizes an 8-bit value for center frequency selection and supports rejection at 20 dB levels located 16% away from the center frequency. It operates on a +3.3 V supply (VDD) and a -2.5 V supply (VSS), drawing 125 µA static current. The component is housed in a compact 10 mm × 10 mm LGA package.

Feature Summary

• Digitally tunable octave band-pass filtering capability
• Configurable via serial peripheral interface (SPI)
• Patented interpolation technique for frequency adjustment

Applications

• Land mobile radios
• Test and measurement equipment
• Military radars and electronic warfare systems
• Satellite communications
• Industrial and medical equipment

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details, as variations exist between bulk and reel formats. Ensure compatibility with standard 3.3 V logic levels for SPI control lines. Confirm moisture sensitivity level ratings prior to surface mount assembly processes.

Selection Notes

Select this component when a single-chip replacement for discrete filter banks is required to reduce system size. Evaluate the dynamic performance metrics, including group delay and settling times, against application requirements. Consider the need for interpolation coefficient calibration if operating outside nominal bandwidth specifications.

Part Context

This part belongs to the ADMV8526 series of RF signal conditioning components. It serves as a direct upgrade path for applications previously relying on large switched filter banks or discrete tunable filters. The device integrates multiple capacitor arrays controlled by digital logic to achieve variable RF performance within a highly compact footprint.
