聯(lián)發(fā)科技股份有限公司(MediaTek, Inc.)是第一個(gè)在無(wú)線充電技術(shù)領(lǐng)域?qū)崿F(xiàn)真正多模兼容功能的廠商，其多模無(wú)線充電接收技術(shù)適用于感應(yīng)式無(wú)線充電和基于帶內(nèi)（in-band）通信的共振式無(wú)線充電，用戶將可享受到多模兼容共振式無(wú)線充電方案的易用性和便利性。

IHS分析師Ryan Sanderson預(yù)計(jì)，2013年無(wú)線充電接收器出貨量約2000萬(wàn)，其中大部分來(lái)源于智能手機(jī)及平板電腦。到2018年，市場(chǎng)規(guī)模將會(huì)增長(zhǎng)到7000億。

聯(lián)發(fā)科技通過(guò)整合共振式技術(shù)，提供創(chuàng)新的多模兼容無(wú)線充電接收解決方案，讓用戶能采用現(xiàn)有的感應(yīng)式充電器或最新的共振式充電器對(duì)裝置進(jìn)行無(wú)線充電。新方案采用松耦合技術(shù)，也就是通稱(chēng)的共振式充電，主要優(yōu)勢(shì)包括：
 . 需充電的裝置可自由放置，相較于感應(yīng)式充電，降低了對(duì)安放位置的要求；
 . 單一無(wú)線充電線圈可同時(shí)對(duì)多個(gè)裝置進(jìn)行充電；
 . 單一無(wú)線充電線圈可對(duì)大小不同、充電功率需求不同的裝置進(jìn)行充電；
 . 支持遠(yuǎn)程充電，即使隔著家具或墻壁也能充電。
