技術名稱: 多模低雜訊天線模組

技術簡介

以多模天線、多模低雜訊放大器、以及帶通濾波器構成一多模低雜訊天線模組,其適用於小型化、高整合度消費產品的射頻前端應用。以目前情況而言,其應用可在兩大領域,第一、可將其整合入高階智慧型手機模組(或高階PDA),使其具有衛星定位(GPS)、衛星數位音訊廣播(SDARS)以及接收行動電視(DVB-H、MediaFLO)的功能。第二、可將其具有有衛星定位(GPS)、衛星數位音訊廣播(SDARS)功能的射頻前端模組獨立成一個小型化車用衛星接收商品。

Abstract

A multimode low noise antenna module composed of multimode antennas, multimode low noise amplifiers and band pass filters that is suitable for miniaturized and high-integrated consumer product. It nowadays can be used to two areas. Firstly, it can be integrated into high-level smart phone or PDA and provides the applications for Global Positioning System (GPS), Satellite Digital Audio Radio Services (SDARS), and Mobile TV (DVB-H or MediaFLO). Secondly, the RF front-end module with GPS and SDARS can be independently produced to a miniaturized vehicle satellite receiver.
