Product details
Overview
BG5412KH6327XTSA1 from Infineon Technologies is a dual N-channel MOSFET tetrode designed for input stages of 2-band tuners, integrating two AGC amplifiers in one SOT-363 package with shared source and gate-2 pins, 8 V VDS, 25 mA continuous drain current per channel, and ultra-low 0.8–1.2 dB noise figure at 45–800 MHz.
For engineers reviewing the BG5412KH6327XTSA1 datasheet, BG5412KH6327XTSA1 pinout, BG5412KH6327XTSA1 application, or BG5412KH6327XTSA1 equivalent, key selection criteria include dual-channel AGC control via single VGG switching line, integrated ESD protection on both gates, cross-modulation performance ≥91 dB at 40 dB AGC, and thermal resistance ≤280 K/W to soldering point.
Technical Context
This device implements a dual-gate, dual-amplifier architecture where Amp A and Amp B share Gate-2 (G2) and Source (S) terminals, enabling coordinated gain control using one external switching voltage (VGG) applied to Pin 3. Each amplifier features fully (Amp A) or partially (Amp B) integrated bias networks.
It operates as a low-noise RF front-end switch-amplifier pair with independent Gate-1 control per channel (Pins 1 and 3), fixed Gate-2 bias (Pin 2), and common RF output paths (Pins 4 and 6). The internal switch toggles conduction states: VGG = 0 V enables Amp A / disables Amp B; VGG = 5 V disables Amp A / enables Amp B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 8 V - maximum drain-source blocking voltage for tuner front-end signal integrity under transient overvoltage |
| ID (per channel) | 25 mA - continuous DC bias current supporting stable small-signal amplification up to 800 MHz |
| Noise figure | 0.8–1.2 dB @ 45–800 MHz - enables high-SNR reception in FM/AM/VHF/UHF tuner input stages |
| Cross-modulation | ≥91 dB @ 40 dB AGC - maintains adjacent-channel interference rejection during strong-signal conditions |
| gfs (typ.) | 33 mS (Amp A), 30 mS (Amp B) - ensures sufficient transconductance for wideband gain control linearity |
| Rth(ch–solder) | ≤280 K/W - supports thermal reliability in compact SOT-363 tuner modules without heatsinking |
| ESD protection | HBM ≥2 kV on all gates - eliminates need for external gate protection diodes in tuner PCB layout |
Pinout & Package
Package: SOT-363 (SC-70-6), 6-pin plastic surface-mount package with 180° rotated tape loading option.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1A) | Gate-1 of Amplifier A | Independent RF gain control input for first tuner band; referenced to shared source |
| 2 (G2) | Common Gate-2 | Bias control node shared by both amplifiers; sets operating point and enables AGC function |
| 3 (G1B) | Gate-1 of Amplifier B | Independent RF gain control input for second tuner band; also serves as VGG switching line |
| 4 (DB) | Drain of Amplifier B | RF output terminal for second tuner band; requires external matching network |
| 5 (S) | Common Source | AC ground reference and DC return path for both amplifiers; connects to system ground plane |
| 6 (DA) | Drain of Amplifier A | RF output terminal for first tuner band; isolated from DB to prevent inter-band coupling |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent AGC amplifiers | Two fully functional RF amplifier channels in one die, sharing G2 and S, reducing board area by ~40% vs discrete solutions |
| Single-line switching control | VGG on Pin 3 toggles active channel without requiring separate logic drivers or timing alignment |
| On-chip gate protection diodes | Integrated ESD clamps on G1A and G1B eliminate need for external 100 Ω + 100 pF RC filters in tuner RF paths |
| Ultra-low noise figure | 0.8 dB typ. @ 45 MHz and 1.1 dB @ 800 MHz enables high-fidelity signal capture in weak-signal environments |
| AEC-Q101 qualified | Stress-tested for automotive tuner applications including temperature cycling, HTRB, and ESD robustness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel AGC amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BGA2865 | Single-channel, 2.5 V operation, no integrated AGC switch; higher gfs (45 mS) but no dual-G1 architecture | Requires external analog switch and dual bias networks for 2-band operation | Select when only one tuner band is needed and lower supply voltage is mandatory |
| BFU760F | Single NPN transistor, 12 GHz fT, no AGC or dual-channel capability; discrete solution needing 2x devices + support passives | Not pin-compatible; increases BOM count and layout complexity for dual-band designs | Select only for ultra-high-frequency (>2 GHz) applications outside tuner frequency ranges |
Compared with BGA2865 and BFU760F, BG5412KH6327XTSA1 uniquely integrates dual independent AGC amplifiers with shared bias and single-line switching-reducing component count by 50%, eliminating inter-channel skew, and maintaining sub-1.2 dB noise across both 45 MHz and 800 MHz bands.

FAQ
What is the maximum allowable gate-source voltage for each amplifier channel?
The absolute maximum gate-source voltage is ±6 V for both Gate-1 terminals (Pins 1 and 3) and ±6 V for Gate-2 (Pin 2), as specified in the Maximum Ratings table. Exceeding these values risks permanent damage to the integrated gate protection diodes and channel oxide integrity.
How does the internal switch control amplifier state transitions?
The internal switch uses Pin 3 (G1B) as the VGG control line: at 0 V, Amp A conducts and Amp B is off; at 5 V, Amp A turns off and Amp B conducts. This is implemented via on-die CMOS-level switching that biases Gate-1 of each FET independently without external logic.
Can BG5412KH6327XTSA1 be used in 5 V supply systems?
Yes - the device operates with VDS up to 8 V and Gate-2 biased at 4 V, making it compatible with standard 5 V rail systems. Drain currents remain within spec (25 mA/channel) at VDS = 5 V, and thermal dissipation stays within Ptot = 200 mW at TS ≤ 94 °C.
Is external matching required on the drain outputs?
Yes - both drain terminals (Pins 4 and 6) require external 50 Ω impedance matching networks for optimal power gain and noise figure. The datasheet provides S-parameter data and recommended microstrip layouts for 45 MHz and 800 MHz bands to achieve specified Gp and F performance.
