In the era of the Internet of everything, every leap forward in Wi-Fi technology means faster, more stable, and smarter connectivity. Today, we are proud to introduce to you a new RF front-end module that disrupts tradition and leads the future - KCT8574HE. Designed for IEEE 802.11a /n/ac/ax WLAN systems, this highly integrated module not only integrates all key RF functions, but also redefines the RF front-end solution for Wi-Fi 6 devices with superior performance, ultra-small package and environmental philosophy.

在KCT8574HE中，高效高线性功率放大器（PA）是其核心组件之一。这款PA不仅具有出色的线性度和效率，更在多种模式下提供了卓越的输出功率。在3.3V供电下，无论是HE160/MCS11模式下的+15.5dBm（@ -43dB DEVM）和+18dBm（@ -40dB DEVM），还是VHT80/MCS9模式下的+19.5dBm（@ -35dB DEVM）和HT20/MCS7模式下的+20.5dBm（@ -30dB DEVM），KCT8574HE都展现了无与伦比的性能优势。这样的输出功率，确保了信号在复杂环境下的强劲传输，让您的Wi-Fi 6设备在任何角落都能保持高速稳定的连接。
In KCT8574HE, high efficiency high linear power amplifier (PA) is one of its core components. This PA not only offers excellent linearity and efficiency, but also provides excellent output power in a variety of modes. Under 3.3V power supply, both +15.5dBm (@-43dB DEVM) and +18dBm (@-40dB DEVM) in HE160/MCS11 mode, As well as +19.5dBm (@-35dB DEVM) in VHT80/MCS9 mode and +20.5dBm (@-30dB DEVM) in HT20/MCS7 mode, the KCT8574HE delivers unmatched performance benefits. This output power ensures robust signal transmission in complex environments, allowing your Wi-Fi 6 device to maintain a high-speed and stable connection anywhere.

低噪声放大器（LNA）在接收链路中扮演着至关重要的角色。KCT8574HE中的LNA不仅具有出色的低噪声特性，还集成了旁路滤波器（BP），有效抑制了带外干扰，提升了接收信号的清晰度和灵敏度。在3.3V供电下，LNA的接收增益为16.5dB，噪声系数为1.7dB。这样的表现，让您的设备在接收信号时更加从容不迫，无论是微弱信号还是复杂环境，都能实现精准接收。
Low noise amplifiers (Lnas) play a crucial role in the receiving link. The LNA in the KCT8574HE not only has excellent low noise characteristics, but also integrates a bypass filter (BP) to effectively suppress out-of-band interference and improve the clarity and sensitivity of the received signal. At 3.3V power supply, the LNA has a receive gain of 16.5dB and a noise figure of 1.7dB. This performance allows your device to receive signals more leisurely, whether weak signals or complex environments, can achieve accurate reception.

KCT8574HE内置了直流电压功率检测功能，让您可以实时监控射频前端的电源状态和射频功率。这一功能对于设备的电源管理和故障排查具有重要意义。通过实时监控，您可以确保设备在正常工作范围内运行，避免潜在的性能问题和安全隐患。
The KCT8574HE has built-in DC voltage power detection, allowing you to monitor the power status and RF power of the RF front end in real time. This function is very important for the power management and troubleshooting of the equipment. With real-time monitoring, you can ensure that devices are operating within normal operating ranges and avoid potential performance issues and security hazards.

KCT8574HE采用了QFN-16L 2.5mm x 2.5mm x 0.55mm的超小封装，这在当前追求小型化、集成化的电子设备市场中，无疑是一个巨大的优势。它不仅节省了宝贵的PCB空间，还为设备的整体设计提供了更多的灵活性和可能性。无论是智能家居、智能安防、智能穿戴设备，还是企业级路由器、无线AP等，KCT8574HE都能轻松融入，为您的设备带来更加出色的性能表现。
The KCT8574HE uses the QFN-16L 2.5mm x 2.5mm x 0.55mm ultra-small package, which is undoubtedly a huge advantage in the current pursuit of miniaturization and integration of electronic devices market. It not only saves valuable PCB space, but also provides more flexibility and possibilities for the overall design of the device. Whether it is smart home, smart security, smart wearable devices, or enterprise-class routers, wireless AP, etc., the KCT8574HE can be easily integrated to bring better performance to your devices.
