Hello, everyone! In this fast-moving era of wireless connectivity, every small technological advance can lead to a revolution. Today, we are proud to introduce a disruptive product, the KCT8528H, a highly integrated RF front-end module designed for IEEE 802.11a /n/ac WLAN systems. This module not only integrates all the key RF functions, but also boasts excellent performance and a small package, making it ideal for Wi-Fi 5 applications!

KCT8528H是一款工作频段覆盖5.15-5.85GHz的射频前端模组，专为满足现代无线通信系统的严苛要求而设计。在这个频段内，它集成了IEEE 802.11 a/n/ac标准所需的所有关键射频组件，包括高效高线性功率放大器（PA）、带有旁路滤波器（BP）的低噪声放大器（LNA）、收发开关（T/R Switch），以及LO抑制和谐波滤波器。这种高度集成的设计不仅简化了系统设计，还大幅提升了整体性能和可靠性。
The KCT8528H is an RF front-end module that operates in the 5.15-5.85GHz band and is designed to meet the demanding requirements of modern wireless communication systems. In this band, it integrates all the key RF components required by the IEEE 802.11a /n/ac standard, including a high-efficiency high-linear power amplifier (PA), a low-noise amplifier (LNA) with a bypass filter (BP), a transceiver Switch (T/R Switch), and LO suppression and harmonic filters. This highly integrated design not only simplifies system design, but also significantly improves overall performance and reliability.

KCT8528H内置的功率放大器（PA）以其高效和高线性度著称。在5V供电下，它能提供高达+25dBm的输出功率（在HT20/MCS7模式下，DEVM=-30dB时），确保信号传输的强劲和稳定。这对于提升无线网络的覆盖范围和穿透力至关重要，特别是在复杂环境中，如多层建筑或密集城市区域。
The KCT8528H's built-in power amplifier (PA) is known for its high efficiency and high linearity. Under 5V power supply, it can provide up to +25dBm output power (in HT20/MCS7 mode, DEVM=-30dB), ensuring robust and stable signal transmission. This is critical to improving the reach and penetration of wireless networks, especially in complex environments such as multi-storey buildings or dense urban areas.

在接收端，KCT8528H配备了低噪声放大器（LNA），其噪声系数在5V供电下仅为1.7dB，能够有效降低接收信号的噪声干扰，提高信号质量。同时，集成的旁路滤波器（BP）进一步增强了抗干扰能力，确保接收到的信号纯净无杂。
At the receiving end, the KCT8528H is equipped with a low noise amplifier (LNA), whose noise factor is only 1.7dB under 5V power supply, which can effectively reduce the noise interference of the received signal and improve the signal quality. At the same time, the integrated bypass filter (BP) further enhances the anti-interference capability, ensuring that the received signal is pure and clutter free.

收发开关（T/R Switch）是射频前端模组中的关键组件，负责在发射和接收模式之间快速切换。KCT8528H内置的收发开关具有高隔离度和低损耗特性，确保信号在发射和接收过程中的高效传输，同时减少信号干扰和能量损失。
The T/R Switch (T/R Switch) is a key component in the RF front-end module that is responsible for quickly switching between transmit and receive modes. The KCT8528H's built-in transceiver switch features high isolation and low loss, ensuring efficient transmission of signals during transmission and reception, while reducing signal interference and energy loss.

内置直流电压功率检测
为了方便系统监控和管理，KCT8528H还内置了直流电压功率检测功能。这一功能可以实时监测输出功率和电压变化，为系统优化和故障排查提供重要数据支持。
Built-in DC voltage power detection
In order to facilitate system monitoring and management, the KCT8528H also has a built-in DC voltage power detection function. This function can monitor the output power and voltage changes in real time, providing important data support for system optimization and troubleshooting.

全面的静电防护
在电子产品的设计中，静电防护是不可忽视的一环。KCT8528H的所有引脚都通过了ESD静电防护标准，有效防止静电放电对模组造成的损害，提高了产品的可靠性和使用寿命。
Comprehensive electrostatic protection
In the design of electronic products, electrostatic protection is an important part. All the pins of KCT8528H have passed the ESD electrostatic protection standard, effectively preventing the damage caused by electrostatic discharge to the module, and improving the reliability and service life of the product.
