MAX3522BCTN+T

Overview

The MAX3522BCTN+T is a radio frequency amplifier designed for DOCSIS 3.1 upstream applications. Manufactured by Analog Devices under the Maxim Integrated brand, this component functions as an upstream amplifier within cable modem systems. It operates in the frequency range of 5 MHz to 86 MHz and provides a typical gain of 20 dB. The device is housed in a compact 4 mm x 4 mm TQFN-EP package with an exposed pad for thermal management.

Feature Summary

• Optimized for DOCSIS 3.1 upstream signal amplification
• Integrated low-noise design for improved signal integrity
• Compact surface-mount packaging for space-constrained layouts

Applications

• DOCSIS 3.1 cable modems
• Upstream signal processing in hybrid fiber-coaxial networks
• Broadband access equipment

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure compatibility with existing PCB footprints for the TQFN-EP package. Check current availability status directly with authorized distributors as supply levels may vary.

Selection Notes

Select this component for designs requiring dedicated upstream amplification in DOCSIS 3.1 environments. Evaluate thermal performance requirements due to the exposed pad design. Compare gain specifications against system link budget needs. Consider the small form factor for high-density board layouts.
