It delivers 21.5 dB gain at 900 MHz with a noise figure of 0.7 dB at that frequency. ## AEC-Q101 qualification and temperature range This part carries AEC-Q101 qualification. It is rated for a junction temperature range of -40 to 150 °C. ## Gain and noise figure — what they mean for the receiver At 21.5 dB gain and 0.7 dB noise figure (900 MHz), the BFU550XRR can serve as the first LNA in a cascaded receiver chain. The 12 V collector-emitter breakdown limits the supply rail in typical bias configurations.","metaTitle":"NXP BFU550XRR RF Transistor NPN 12V 11GHz SOT-143R AEC-Q101","metaDescription":"NXP BFU550XRR RF NPN transistor, 12V Vceo, 11GHz fT, 21.5dB gain at 900 MHz, 0.7dB noise figure, SOT-143R, AEC-Q101 automotive qualified.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Gain":"21.5dB","Series":"Automotive, AEC-Q101","Package":"Tape & Reel (TR); Cut Tape (CT)","Power - Max":"450mW","Mounting Type":"Surface Mount","Package / Case":"SOT-143R","Transistor Type":"NPN","lifecycle_stage":"eol_hot","Operating Temperature":"-40°C ~ 150°C (TJ)","Frequency - Transition":"11GHz","Supplier Device Package":"SOT-143R","Noise Figure (dB Typ @ f)":"0.7dB @ 900MHz","Current - Collector (Ic) (Max)":"50mA","DC Current Gain (hFE) (Min) @ Ic, Vce":"60 @ 15mA, 8V","Voltage - Collector Emitter Breakdown (Max)":"12V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.44","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.44000","currency":"USD"},{"qty":10,"price":"$0.33000","currency":"USD"},{"qty":25,"price":"$0.29760","currency":"USD"},{"qty":100,"price":"$0.20560","currency":"USD"},{"qty":250,"price":"$0.17312","currency":"USD"},{"qty":500,"price":"$0.14066","currency":"USD"},{"qty":1000,"price":"$0.10820","currency":"USD"},{"qty":3000,"price":"$0.09738","currency":"USD"},{"qty":6000,"price":"$0.09197","currency":"USD"},{"qty":15000,"price":"$0.08981","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/035011ca09f255b2ec940958c3ac4816.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BFU550XRR automotive qualified (AEC-Q101)?","answer":"Yes, the BFU550XRR is AEC-Q101 qualified, as indicated by its Automotive series designation.
