SA606D

低壓高性能混頻器FM IF系統(tǒng)

SA606是低壓高性能單片F(xiàn)M IF系統(tǒng)，集成了一個混頻器/振蕩器、兩個限幅中頻放大器、正交檢波器、對數(shù)接收信號強度指示器(RSSI)、電壓調(diào)節(jié)器以及音頻和RSSI運算放大器。SA606采用SO20和SSOP20封裝。\nSA606專門針對便攜式通信應(yīng)用而設(shè)計，其工作電壓可低至2.7 V。RF部分與著名的SA605類似。音頻和RSSI輸出具有可訪問反饋路徑的放大器。因此，設(shè)計人員能夠調(diào)整輸出電平或添加濾波。\n; 低功耗：3.5 mA典型值（3 V時）\n混頻器輸入達150 MHz以上\n45 MHz時17 dB的混頻器轉(zhuǎn)換功率增益\nXTAL振蕩器有效頻率達150 MHz（LC振蕩器或外部振蕩器可在更高頻率下使用）\n102 dB的IF放大器/限幅器增益\n2 MHz的IF放大器/限幅器小信號帶寬\n溫度補償對數(shù)RSSI，具有90 dB動態(tài)范圍\n外部元器件數(shù)少；適合晶體/陶瓷/ LC濾波器\n出色的靈敏度：在1 kHz音頻信號（RF為45 MHz、IF為455 kHz）時，信噪和失真比(SINAD)為12 dB，對于50 Ω匹配網(wǎng)絡(luò)為0.31 μV\nSA606符合蜂窩無線電規(guī)范\n音頻輸出內(nèi)部運算;
