Product details
Overview
BF1005E6327HTSA1 from Infineon Technologies is a silicon N-channel dual-gate MOSFET tetrode designed for low-noise, high-gain RF input stages up to 1 GHz. It features integrated biasing (G1 externally biased, G2 self-biased), 5 V operating voltage, 1.6 dB typical noise figure at 800 MHz, 19 dB typical power gain, and SOT143 package with Pb-free RoHS compliance.
For engineers reviewing the BF1005E6327HTSA1 datasheet, BF1005E6327HTSA1 pinout, BF1005E6327HTSA1 application, or BF1005E6327HTSA1 equivalent, key selection criteria include dual-gate noise performance, VG2S-dependent gain control range (40–50 dB), self-biasing capability (IDSO = 8–16 mA), and thermal resistance (Rthchs ≤ 370 K/W) in RF front-end amplifier design.
Technical Context
This tetrode operates with Gate 1 (G1) as RF input terminal and Gate 2 (G2) as gain-control terminal, enabling independent signal injection and transconductance tuning. Its dual-gate architecture isolates RF input from DC bias path, minimizing feedback and improving stability in broadband amplifiers.
Designed for self-biased operation at VDS = 5 V and VG2S = 4 V, it delivers IDSO = 10 mA typ., gfs = 24 mS typ., and Cg1ss = 2.1 pF typ. at 10 MHz - parameters critical for impedance matching and noise optimization in UHF receiver front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise figure | 1.6 dB typ. at 800 MHz - enables high-sensitivity reception in sub-1 GHz wireless receivers |
| Power gain | 19 dB typ. at 800 MHz - supports single-stage amplification without cascading in compact RF modules |
| Gain control range | 40–50 dB at 800 MHz - allows wide dynamic range AGC implementation via VG2S sweep from 4 V to 0 V |
| Forward transconductance | 24 mS typ. at VDS = 5 V, VG2S = 4.5 V - determines small-signal gain linearity and bandwidth trade-off |
| Gate1 input capacitance | 2.1 pF typ. at 10 MHz - sets input matching network component values and affects input return loss |
| Drain current (self-biased) | 10 mA typ. at VDS = 5 V, VG2S = 4 V - defines quiescent power dissipation (≈50 mW) and thermal headroom |
| Channel temperature limit | 150 °C - constrains maximum ambient operating temperature under Ptot = 200 mW derating curve |
Pinout & Package
SOT143 package: 4-pin surface-mount plastic package with standard 1.3 mm × 1.7 mm footprint, 0.65 mm pitch, and exposed drain pad for thermal enhancement. Pin 1 = Source (S), Pin 2 = Drain (D), Pin 3 = Gate 2 (G2), Pin 4 = Gate 1 (G1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (S) | Source terminal | Common reference node for both gates; connects to RF ground or bias return path |
| Pin 2 (D) | Drain terminal | RF output node; requires DC blocking and impedance matching to 50 Ω system |
| Pin 3 (G2) | Gain-control gate | DC bias input for transconductance tuning; controls IDSO and gain without affecting RF input impedance |
| Pin 4 (G1) | RF input gate | High-impedance RF signal entry point; isolated from G2 to minimize feedthrough and improve reverse isolation |
Key Features
| Feature | Design Value |
|---|---|
| Dual-gate tetrode structure | Enables simultaneous RF signal injection (G1) and gain control (G2) with >30 dB reverse isolation |
| Integrated biasing network | Eliminates external bias resistors for G2, reducing PCB area and parasitic inductance in 800–1000 MHz layouts |
| Low-noise performance | 1.6 dB NF at 800 MHz supports high dynamic range in GPS, ISM-band, and analog TV tuners |
| Pb-free RoHS compliance | Meets EU Directive 2011/65/EU; qualified per AEC-Q101 Grade 2 for automotive infotainment RF modules |
| Thermal resistance | Rthchs ≤ 370 K/W enables stable operation up to 76 °C case temperature at full 200 mW rating |
Applications
| GPS Receiver Front-End | ISM-Band Wireless Sensor Node |
|---|---|
Use Scenario: Low-power GPS L1-band (1575.42 MHz) signal amplification before downconversion. IC Role / Device Role / Timing Role: First-stage low-noise amplifier (LNA) with gain control for varying satellite signal strength. Use Value: 1.6 dB noise figure preserves carrier-to-noise ratio; 40 dB gain control range adapts to urban canyon vs. open-sky conditions. | Use Scenario: Sub-GHz RF front-end in battery-powered industrial sensor transceivers (e.g., 868/915 MHz). IC Role / Device Role / Timing Role: Self-biased LNA with programmable gain for adaptive sensitivity in mesh networks. Use Value: 10 mA IDSO enables <100 mW DC consumption; SOT143 footprint fits space-constrained PCBs with minimal matching components. |

IC Role / Device Role / Timing Role: Fixed-gain IF amplifier stage requiring stable transconductance and low distortion. Use Value: 24 mS gfs ensures linear amplification across channel bandwidth; dual-gate structure suppresses intermodulation from adjacent channels. | Use Scenario: DAB/DAB+ band I (174–240 MHz) and band III (223–230 MHz) RF amplification in automotive head units. IC Role / Device Role / Timing Role: AEC-Q101-qualified LNA supporting vibration-resistant, thermally robust receiver design. Use Value: AEC-Q101 Grade 2 qualification ensures reliability at 105 °C under hood; 19 dB gain reduces need for additional gain stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-gate MOSFET LNA applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BFP181H6327XTSA1 | Higher fT (6 GHz vs. 4 GHz), lower Cg1ss (1.7 pF), but no integrated G2 biasing network | Requires external G2 bias resistor; better suited for discrete-tuned VHF/UHF amplifiers | Select when higher frequency operation (>1 GHz) and tighter layout control outweigh self-biasing convenience |
| MCH4008-TL-E | Single-gate GaAs pHEMT; 0.5 dB lower NF (1.1 dB), but no gain control capability and non-RoHS package | Lacks VG2S-based AGC; used only where absolute minimum noise dominates over dynamic range needs | Select only for ultra-low-noise fixed-gain applications where gain control is implemented externally |
Compared with BFP181H6327XTSA1 and MCH4008-TL-E, BF1005E6327HTSA1 uniquely combines integrated G2 biasing, 40–50 dB gain control, and AEC-Q101 qualification - making it optimal for cost-sensitive, thermally constrained automotive and consumer RF front-ends requiring adaptive sensitivity.

FAQ
Can BF1005E6327HTSA1 be operated with external DC bias applied to Gate 1?
No. The datasheet explicitly warns against applying external DC voltage to Gate 1 in active mode. G1 is intended solely as an RF input terminal; biasing must be applied only to Gate 2 (G2). External DC on G1 risks device degradation and violates the specified operating conditions.
What is the maximum allowable drain-source voltage during transient conditions?
The absolute maximum drain-source voltage is 8 V under continuous operation. Transient overvoltage beyond this rating - even briefly - may cause avalanche breakdown or permanent damage, as V(BR)DS is rated at 12 V only under pulsed test conditions (ID = 650 μA, VG1S = VG2S = 0 V).
How does thermal derating affect usable power at 105 °C ambient?
At TS = 105 °C, total power dissipation must be reduced to ≈80 mW per the Ptot vs. TS curve. This corresponds to ID ≈ 16 mA at 5 V, limiting RF output power and requiring careful thermal design in enclosed automotive environments.
Is SOT143 pinout compatible with SOT143R for board-level replacement?
No. SOT143 and SOT143R have reversed pin assignments: SOT143 uses Pin 1=S, Pin 2=D, Pin 3=G2, Pin 4=G1; SOT143R swaps G1/G2 positions (Pin 3=G1, Pin 4=G2). Mechanical compatibility does not imply electrical interchangeability.
