三星第四代智能手機Galaxy S4采用了RFMD的多個3G/4G LTE RF元件，包括RF7388多模多頻段3G/4G PA、多個RF73xx系列超高效率LTE PA和業(yè)界領(lǐng)先的天線控制解決方案。
RFMD蜂窩產(chǎn)品部總裁Eric Creviston說：“RFMD在全球領(lǐng)先智能手機制造商中的知名度正在快速上升，并正在將領(lǐng)先地位快速擴展到高增長度的LTE領(lǐng)域。我們期望我們的RF產(chǎn)品能更多地打進全球領(lǐng)先的LTE設(shè)備，因為2013年主要的LTE新項目正在引入或起飛。”
RF高度集成的RF7388 PA覆蓋頻段1、2、3、4、5、6、8、9、10、15、18、19、20、26、27、33、35、37和39，并提供多模多頻段封裝下業(yè)界最好的效率。與RFMD的RF7307、RF7320和RF7321超高效率衛(wèi)星單頻段4G LTE PA配合使用時，可分別提供對LTE頻段7、20和11/21的額外覆蓋。
除了RF7388、RF7307、RF7320和RF7321以外，RFMD還提供RF1119天線控制解決方案來優(yōu)化和最小化Galaxy S4的天線功能。RF1119與領(lǐng)先的4G LTE基帶兼容，設(shè)計用于在高數(shù)據(jù)速率、多頻段多模應(yīng)用中提供最優(yōu)的RF性能。RF1119天線控制解決方案允許實現(xiàn)更薄的智能手機，通過降低掉話和提升數(shù)據(jù)吞吐速率幫助擴大網(wǎng)絡(luò)覆蓋范圍。
RF7388多模多頻段PA兼容領(lǐng)先的4G LTE基帶，支持先進的電源管理功能，在高數(shù)據(jù)速率應(yīng)用中可實現(xiàn)更高的系統(tǒng)效率。RFMD提供單模、多模和整合架構(gòu)的3G/4G LTE解決方案，覆蓋所有的3G、4G LTE和TD-LTE頻段。
三星Galaxy S4不僅采用了RFMD的超高效率3G/4G功放和多個開關(guān)類元件，還采用了RFMD PowerSmart電源平臺。

RFMD 4G multimode PA Selected by Samsung Galaxy S4 Smartphone
【Lead-in】Galaxy S4 selected RFMD multi-mode, multi-frequency 3G/4G PA RF7388 which could covers bands 1, 2, 3, 4, 5, 6, 8, 9, 10, 15, 18, 19, 20, 26, 27, 33, 35, 37, and 39, and delivers best-in-class efficiency in a multimode multi-band package.
RFMD is global leader in the design and manufacture of high-performance radio frequency solutions RFMD, it has been selected by a leading smartphone manufacturer to supply multiple 3G/4G LTE components into a recently announced fourth-generation flagship smartphone platform. The highly anticipated smartphones will feature RFMD''''s recently announced RF7388 multimode multi-band (MMMB) 3G/4G PA, multiple variants of RFMD''''s RF73xx family of ultra-high efficiency LTE PAs, and RFMD''''s industry-leading antenna control solutions.
Eric Creviston, president of RFMD''''s Cellular Products Group, said, "RFMD is rapidly increasing our exposure to the world''''s leading smartphone manufacturers and extending our position in the high-growth LTE category. We expect to grow our content in the world''''s leading LTE devices as major new programs are introduced and ramp throughout calendar 2013."
RFMD''''s highly integrated RF7388 PA covers bands 1, 2, 3, 4, 5, 6, 8, 9, 10, 15, 18, 19, 20, 26, 27, 33, 35, 37, and 39, and delivers best-in-class efficiency in a multimode multi-band package. It is mated with RFMD''''s RF7307, RF7320, and RF7321 ultra-high efficiency satellite single-band 4G LTE PAs to provide additional coverage for LTE bands 7, 20, and 11/21, respectively.
In addition to the RF7388, RF7307, RF7320, and RF7321, RFMD will supply its RF1119 antenna control solution to optimize and miniaturize the antenna function across this global smartphone platform. The RF1119 is compatible with the leading 4G LTE basebands and is designed to deliver optimal RF performance in high data-rate, high band-count multimode applications.
