Abstract: A miniaturized and reusable receiving front-end applying to satellite communication is designed in the paper, which converts RF signal of 950 MHz to 2 150 MHz to IF by preselected filtering, amplifying and mixing. The design scheme of the circuit is introduced first, and the key indicators are analyzed. The receiving front-end is 105 mm×55 mm×9.5 mm in size. Miniaturization and universal were realized in the paper, which can be reused in various satellite communication devices.
Key words : receiving front-end;reusable,;miniaturized

隨著科學(xué)技術(shù)的不斷進(jìn)步和世界各國(guó)對(duì)電子戰(zhàn)的不斷重視,衛(wèi)星通信的重要程度尤為突出,,也有更多的國(guó)家打造自己的衛(wèi)星通信體系。接收前端作為衛(wèi)星通信設(shè)備的重要組成部分,,其一直以來(lái)都以定制化為主,,致使其研發(fā)成本較高、研發(fā)周期較長(zhǎng),、體積較大且外形各異,,不利于統(tǒng)型。在國(guó)家大力發(fā)展衛(wèi)星通信的大環(huán)境下,,研發(fā)一款應(yīng)用于衛(wèi)星通信領(lǐng)域的小型化,、可復(fù)用的接收前端具有重大意義。
