IPQ-4028-0-180DRQFN-SR-00-0

Overview

The IPQ4028 is a single-chip Wi-Fi system-on-chip (SoC) from Qualcomm Technologies, designed for home and enterprise networking products. It integrates dual-band 802.11ac Wave-2 features with network processing capabilities. The device supports up to four CPU cores with clock speeds reaching 717 MHz and includes 256 MB of RAM density. It provides five Ethernet ports and delivers peak Wi-Fi speeds up to 1.266 Gbps across 2.4 GHz and 5 GHz spectral bands. The chip utilizes a 2x2 MIMO configuration with support for spatial streams up to two, enabling high-performance, power-efficient infrastructure solutions.

Feature Summary

• Integrates dual-band 802.11ac Wave-2 Wi-Fi connectivity with advanced network processing in a single-chip design.
• Supports multi-user multiple-input multiple-output (MU-MIMO) and transmit beamforming (TxBF) technologies.
• Includes hardware-based security features such as AES-CCMP and AES-GCMP encryption standards.

Applications

• Small cellular base station radios
• 3G/4G/5G macro systems
• Home and enterprise networking infrastructure

Procurement Notes

Verify the exact part marking against official Qualcomm documentation to confirm the specific revision and package variant. Ensure compatibility with required firmware versions for MU-MIMO and TxBF functionality. Confirm thermal management requirements for the QFN package in the target application environment. Validate supply chain authenticity through authorized distributors to avoid counterfeit components.

Selection Notes

Select this component for applications requiring integrated dual-band Wi-Fi 5 performance with embedded network processing. Consider the 717 MHz processor speed and 256 MB RAM capacity for complex routing tasks. Evaluate the five-port Ethernet interface against port count requirements. Assess power efficiency needs for battery-constrained or thermally limited deployments.
