超低失真IF VGA

AD8375是一款數(shù)字控制、可變?cè)鲆?、寬帶寬放大器，可以提供精密增益控制、高IP3與低噪聲系數(shù)。出眾的低失真性能與寬信號(hào)帶寬使得AD8375成為多種接收機(jī)應(yīng)用中的卓越增益控制器件。AD8375采用先進(jìn)的高速SiGe工藝制作，集成專有失真消除技術(shù)，在200 MHz時(shí)能獲得50 dBm的IP3輸出。AD8375能以1dB的分辨率提供24 dB寬增益范圍。通過可由標(biāo)準(zhǔn)TTL電平驅(qū)動(dòng)的5引腳控制接口對(duì)增益進(jìn)行調(diào)整，開集輸出提供靈活的接口，允許利用負(fù)載阻抗來設(shè)置整個(gè)信號(hào)范圍增益。因此，信號(hào)電壓增益與負(fù)載成正比。AD8375的電源由PWUP引腳的適當(dāng)邏輯電平提供。其靜態(tài)電流典型值為130 mA。在省電模式 ? 24引腳，4 mm × 4 mm LFCSP封裝\n\n? 5 V單電源供電 \n\n? 關(guān)斷特性 \n\n? 噪聲系數(shù)：8 dB（最大增益時(shí)）\n\n? 增益范圍：-4 dB至+20 dB\n\n? 差分輸入與輸出 \n\n? 帶寬：630 MHz (?3 dB)\n\n? 并行5位控制接口\n\n? 提供穩(wěn)定的SFDR與增益變化關(guān)系\n\n? 步長：1 dB ± 0.2 dB \n\n? 輸出IP3：~50 dBm (200 MHz)\n\n? 輸出P1dB：19 dBm (200 MHz);
