康希通信射頻前端模塊美林美深科技KCT8227H型號

在這個萬物互聯(lián)的時代，Wi-Fi技術(shù)正以前所未有的速度推動著數(shù)字生活的變革。隨著Wi-Fi 6的普及，用戶對網(wǎng)絡(luò)速度、穩(wěn)定性和能效的要求也日益提高。在這樣的背景下，一款集高性能、高集成度與環(huán)保理念于一身的射頻前端模組——KCT8227H應(yīng)運(yùn)而生，它專為2.4-2.5GHz頻段設(shè)計，旨在為用戶提供前所未有的Wi-Fi體驗。
In this era of the Internet of everything, Wi-Fi technology is driving the transformation of digital life at an unprecedented speed. With the popularity of Wi-Fi 6, users are increasingly demanding network speed, stability and energy efficiency. In this context, a high-performance, highly integrated and environmentally friendly RF front-end module - KCT8227H came into being, which is designed for the 2.4-2.5GHz band, aiming to provide users with unprecedented Wi-Fi experience.

KCT8227H是一款專為802.11b/g/n/ac WLAN系統(tǒng)定制的高集成射頻前端模組，它集成了實現(xiàn)高效通信所需的所有關(guān)鍵射頻組件，包括但不限于高效率高線性功率放大器（PA）、低噪聲放大器（LNA）配以旁路濾波器（BP）、LO抑制和諧波濾波器，以及內(nèi)置的直流電壓功率檢測功能。這一設(shè)計不僅大幅簡化了射頻前端的設(shè)計復(fù)雜度，還顯著減少了外部電路的需求，使得系統(tǒng)集成更加便捷，成本效益更高。
The KCT8227H is a highly integrated RF front-end module customized for 802.11b/g/n/ac WLAN systems, which integrates all the key RF components needed for efficient communication. Includes but is not limited to high efficiency high linear power amplifiers (PA), low noise amplifiers (LNA) with bypass filters (BP), LO suppression and harmonic filters, and built-in DC voltage power detection. This design not only greatly simplifies the design complexity of the RF front-end, but also significantly reduces the need for external circuits, making system integration easier and more cost-effective.

在性能方面，KCT8227H展現(xiàn)出了非凡的實力。其集成的2.4GHz PA在VHT40/MCS9配置下，能以+22dBm的輸出功率實現(xiàn)-35dB的DEVM（誤差向量幅度），確保了數(shù)據(jù)傳輸?shù)母咝逝c穩(wěn)定性；而在HT20/MCS7配置下，輸出功率更是高+23.5dBm，DEVM僅為-30dB，滿足了高速數(shù)據(jù)傳輸?shù)膰?yán)苛要求。此外，31dB的發(fā)射增益和15dB的接收增益，配合1.6dB的低噪聲系數(shù)，即便在復(fù)雜多變的無線環(huán)境中，也能保證信號的清晰度和接收靈敏度，讓每一次連接都穩(wěn)定如初。
In terms of performance, the KCT8227H shows extraordinary strength. Its integrated 2.4GHz PA in VHT40/MCS9 configuration can achieve -35dB DEVM (error vector amplitude) with an output power of +22dBm, ensuring high efficiency and stability of data transmission; In the HT20/MCS7 configuration, the output power is higher than +23.5dBm, and the DEVM is only -30dB, meeting the strict requirements of high-speed data transmission. In addition, the transmit gain of 31dB and the receive gain of 15dB, combined with the low noise factor of 1.6dB, can ensure the clarity of the signal and the receive sensitivity, even in the complex and changeable wireless environment, so that every connection is stable as before.

在追求高性能的同時，KCT8227H也沒有忽視對空間利用率的優(yōu)化。其采用QFN-16L封裝形式，尺寸僅為2.5×2.5×0.55mm，是市場上同類產(chǎn)品中的佼佼者。這一超小封裝設(shè)計不僅為終端設(shè)備的設(shè)計者提供了更大的靈活性，使得產(chǎn)品可以更加輕松地融入各種緊湊的空間布局中，同時也為未來的小型化、輕量化設(shè)計趨勢奠定了堅實的基礎(chǔ)。
While pursuing high performance, the KCT8227H does not neglect the optimization of space utilization. It comes in the form of QFN-16L package with a size of only 2.5×2.5×0.55mm, which is the leader in similar products on the market. This ultra-small package design not only provides the designer of the terminal equipment with greater flexibility, so that the product can be more easily integrated into a variety of compact space layout, but also lays a solid foundation for the future of miniaturization and lightweight design trends.
