收音系列產(chǎn)品

SP7021F 內(nèi)包含有高放、混頻、本振、二級有源中頻濾波器、中頻限幅放大器、鑒頻器、低頻器、低頻放大器、靜噪電路以及相關(guān)靜噪系統(tǒng)等，它具有單聲道FM 收音機的全部功能。工作電源電壓范圍為1.8~6V，推薦值為3V。它適用單聲道或立體聲FM 收音機，尤其適用于低壓微調(diào)諧系統(tǒng)。該電路采用 16 腳雙列扁平封裝。 ·由于中頻頻率很低，只有76kHz，因此中頻濾波由內(nèi)電路兩級有源濾波器來實現(xiàn)，在外電路取消了中周變壓器或陶瓷濾波器，減化了電路調(diào)整，縮小了體積。\n·輸入回路不需要調(diào)諧，采用寬頻帶接收，通過改變本振調(diào)諧頻率來選擇電臺信號。高頻輸入信號頻率范圍為1.5~110MHz。\n·電路內(nèi)設(shè)有由混頻、限幅中放、鑒頻、本振（VCO）組成的頻率鎖相環(huán)電路，用來對中頻頻偏進(jìn)行壓縮，以滿足廣播信號的頻帶寬度。\n·電路內(nèi)設(shè)有由相關(guān)靜噪系統(tǒng)及靜噪電路組成的降噪系統(tǒng)，可用于抑制無信號時、電源開關(guān)轉(zhuǎn)換時以及接收弱信號時的噪聲，提高信噪比。\n·;
