QuantalRF announces the sampling of its innovative Wi-Fi 7 CMOS front-end module , the QWX27120, to two Tier-1 mobile SoC players. This state-of-the-art 5-7 GHz CMOS FEM is designed specifically for Wi-Fi 7 applications, integrating a patent-pending power amplifier architecture, an SP3T switch, and a low-noise amplifier into a single monolithic CMOS die.
Optimized for a wide range of devices including smartphones, AR/VR, tablets, laptops, and smart home devices, the QWX27120 is designed to perform better than GaAs and SiGe products in terms of power efficiency, size, RF performance, and cost. As part of the QuantalRF Elementum family of Wi-Fi 7 products, the QWX27120 builds on the success of its predecessors with enhanced features, including a power detector output.
The QWX27120 is compatible with both Wi-Fi 6E and Wi-Fi 7, supporting a frequency range of 5150–7125 MHz. It boasts superior power efficiency, reducing power consumption by up to 50%. Additionally, it features a power detector output that provides real-time power monitoring. The module's ultra-small form factor integrates all RF front-end components into a single die, available in a 2 x 2mm LGA package or as a flip-chip die.
Fabricated using CMOS SOI technology, the QWX27120 leverages QuantalRF’s unique PA architecture to significantly reduce power consumption, enabling longer battery life and reduced heat dissipation. The CMOS FEM also offers a high degree of on-chip configurability, allowing versatile reconfiguration for different supply voltages, channels, and operational modes. Selectable high/low transmit gain modes and digital pre-distortion further enhance power efficiency.
The innovative power amplifier architecture integrated within the QWX27120 reduces power consumption by up to 50% compared to traditional GaAs and SiGe solutions. This means devices using this module can operate longer on a single battery charge, which is particularly beneficial for mobile devices like smartphones, tablets, and AR/VR headsets. By minimizing power usage, the QWX27120 helps extend the battery life of devices, which is crucial for users who rely on their devices throughout the day without frequent recharging. Efficient power usage also translates to less heat generation, helping maintain optimal device performance and longevity, as excessive heat can degrade electronic components over time. The power detector output feature provides real-time power monitoring, allowing for better power management and optimization, ensuring that the device operates efficiently under various conditions. Additionally, the QWX27120 supports selectable high/low transmit gain modes and digital pre-distortion, further enhancing power efficiency by allowing the device to adapt its power usage based on operational requirements.
“Wi-Fi 7’s advanced features and higher data rates pose significant power consumption challenges,” said Dr. Ali Fard, CEO and CTO of QuantalRF. “Our innovative PA architecture—integrated within a monolithic CMOS SOI platform—delivers superior linear output power and best-in-class power efficiency. With the QWX27120 Wi-Fi 7 FEM now sampling.”
