Product details
Overview
BFR93AW E6327 from Infineon Technologies is a low-noise silicon bipolar RF transistor designed for high-linearity amplification and oscillator circuits up to 2 GHz, with fT = 6 GHz (typ), NFmin = 1.5 dB at 900 MHz, and Gma = 15.5 dB at 900 MHz - deployed in cellular front-end modules and UHF receiver LNA stages.
For engineers reviewing the BFR93AW E6327 datasheet, BFR93AW E6327 pinout, BFR93AW E6327 application, or BFR93AW E6327 equivalent, key selection criteria include noise figure vs. bias current trade-off, SOT323 thermal resistance (RthJS = 140 K/W), third-order intercept point (IP3 = 15 dBm), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This NPN RF transistor operates with VCEO = 12 V and IC = 90 mA max, optimized for small-signal amplification under 5–30 mA collector bias. Its fT of 6 GHz (typ) and Ccb = 0.58 pF (typ) support stable gain and matching up to 1.8 GHz.
Designed for low-distortion operation, it delivers P-1dB = 6 dBm and IP3 = 15 dBm at 900 MHz with 50 Ω terminations, enabling use in GSM/UMTS/LTE band-selective receive paths where linearity and noise floor are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 12 V - maximum safe collector-emitter voltage before breakdown under operating conditions |
| fT | 6 GHz (typ) - unity-gain frequency defining usable RF bandwidth for small-signal amplification |
| NFmin | 1.5 dB at 900 MHz - lowest achievable noise figure at optimal source impedance, critical for LNA sensitivity |
| Gma | 15.5 dB at 900 MHz - maximum available power gain under conjugate match, determines stage gain ceiling |
| IP3 | 15 dBm - third-order intercept point indicating linearity headroom for two-tone intermodulation suppression |
| RthJS | 140 K/W - junction-to-soldering-point thermal resistance, constrains continuous power dissipation in PCB layout |
| AEC-Q101 | Qualified - certified for automotive electronics per stress test standard, supporting under-hood and infotainment applications |
Pinout & Package
Package: SOT323 - surface-mount plastic package with visible leads, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal for forward-biased junction; requires DC bias network and RF choke or capacitor coupling |
| 2 | Emitter (E) | Common reference node; typically grounded via low-inductance path for RF stability and noise control |
| 3 | Collector (C) | Output terminal; connects to RF output matching network and DC supply through RF choke |
Key Features
| Feature | Design Value |
|---|---|
| Low noise figure | NFmin = 1.5 dB at 900 MHz enables high-sensitivity receiver front-ends in sub-2 GHz bands |
| High transition frequency | fT = 6 GHz (typ) supports stable gain and matching up to 1.8 GHz without parasitic roll-off |
| Linearity performance | IP3 = 15 dBm and P-1dB = 6 dBm allow simultaneous reception of weak and strong signals in crowded spectrum |
| AEC-Q101 qualification | Validated for automotive temperature range (−65 °C to +150 °C) and reliability stress testing |
| SOT323 thermal design | RthJS = 140 K/W enables 300 mW total dissipation with proper PCB copper area and soldering |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise RF transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BFP640FESD | fT = 25 GHz, NFmin = 0.75 dB at 1.8 GHz, SOT343 package, higher cost | Targets 2.4 GHz WiFi/BT coexistence designs requiring lower noise and wider bandwidth | Select when operating above 1.8 GHz or needing sub-1 dB noise; not drop-in due to different pinout and bias requirements |
| MRF9011LSR3 | fT = 8 GHz, NFmin = 1.8 dB at 900 MHz, TO-243AA package, higher Ptot = 500 mW | Used in higher-power base station repeaters where thermal margin and ruggedness outweigh size constraints | Prefer for industrial fixed infrastructure; incompatible with SOT323 footprint and requires larger heatsinking |
Compared with BFR93AW E6327, BFP640FESD offers superior high-frequency noise performance but demands redesign for layout and bias, while MRF9011LSR3 trades compactness for thermal robustness - making BFR93AW E6327 optimal for space-constrained, automotive-qualified 900 MHz/1.8 GHz portable RF front-ends.

FAQ
What is the recommended DC bias condition for minimum noise figure?
The datasheet specifies NFmin = 1.5 dB at IC = 5 mA and VCE = 8 V with optimal source impedance (ZSopt). This bias point balances noise performance and gain stability; increasing IC beyond 10 mA degrades NF due to increased shot noise, while reducing below 3 mA raises thermal noise contribution.
Is BFR93AW E6327 suitable for 5G NR sub-6 GHz bands?
No - its fT = 6 GHz (typ) and verified AC characteristics only extend to 1.8 GHz per datasheet test conditions. At 3.5 GHz, gain rolls off significantly and NF increases beyond 3 dB; it is not characterized or guaranteed for n78/n77 band operation.
How does the SOT323 package affect thermal management in continuous operation?
With RthJS = 140 K/W, the SOT323 limits continuous Ptot to 300 mW only if the soldering point remains ≤108 °C. Achieving this requires ≥25 mm² of 1-oz copper on the collector pad and minimal thermal via resistance; exceeding 200 mW without thermal enhancement risks junction overheating.
Does the AEC-Q101 qualification cover all electrical parameters across temperature?
AEC-Q101 qualification confirms reliability under stress (HTOL, TC, HAST, etc.) but does not guarantee full parameter compliance across −65 °C to +150 °C. The datasheet specifies electrical characteristics only at TA = 25 °C; for automotive use, designers must validate hFE, fT, and NF at −40 °C and +125 °C using application-specific test setups.
