It is housed in a 4-TSFP package for surface-mount assembly. ## Noise figure and gain — LNA stage fit With a 0.95 dB noise figure at 1.8 GHz, this transistor suits the first LNA stage in GPS, cellular, and ISM-band receivers where the noise floor sets the system sensitivity. The 22.5 dB gain means a single stage can lift a -100 dBm signal to a detectable level without a second gain block. Collector current is rated to 40 mA maximum, and the 3.5 V Vce breakdown limits the supply rail — typical for battery-powered and low-voltage RF front-ends. The 100 mW power dissipation ceiling is adequate for small-signal stages but rules out driver or output amplifier roles.","metaTitle":"BFP520FE6327 NPN RF Transistor, 45 GHz fT, 22.5 dB Gain","metaDescription":"Infineon BFP520FE6327 NPN Si RF transistor. 45 GHz transition frequency, 22.5 dB gain, 0.95 dB noise figure at 1.8 GHz. 4-TSFP package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":[],"specifications":{"Gain":"22.5dB","Package":"Bulk","Power - Max":"100mW","Mounting Type":"Surface Mount","Package / Case":"4-SMD, Flat Leads","Transistor Type":"NPN","lifecycle_stage":"eol_hot","Operating Temperature":"150°C (TJ)","Frequency - Transition":"45GHz","Supplier Device Package":"4-TSFP","Noise Figure (dB Typ @ f)":"0.95dB @ 1.8GHz","Current - Collector (Ic) (Max)":"40mA","DC Current Gain (hFE) (Min) @ Ic, Vce":"70 @ 20mA, 2V","Voltage - Collector Emitter Breakdown (Max)":"3.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.15","stockQuantity":0,"priceTiers":[{"qty":2046,"price":"$0.15000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f6777463fb4719ee271434b307e7f9e8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BFP520FE6327 obsolete?","answer":"No discontinuation or last-time-buy has been announced."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BFP520FE6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BFP520FE6327 when reusing this data.
