Product details
BG5120KE6327HTSA1 from Infineon Technologies
BG5120KE6327HTSA1 from Infineon Technologies is a dual N-channel RF tetrode MOSFET designed for low-noise, high-dynamic-range AGC amplifier stages in VHF/UHF tuner front-ends. It integrates two independent amplifiers (A and B) with separate gate controls (G1, G2), 1.1 dB noise figure at 45 MHz, 23 dB typical power gain at 800 MHz, and ±6 V gate-source voltage rating - deployed in NTSC/PAL broadcast tuners requiring simultaneous signal amplification and automatic gain control.
For engineers reviewing the BG5120KE6327HTSA1 datasheet, BG5120KE6327HTSA1 pinout, BG5120KE6327HTSA1 application, or BG5120KE6327HTSA1 equivalent, key selection criteria include its dual-channel AGC architecture, SOT363 package thermal resistance (≤280 K/W), 20 mA continuous drain current per channel, and verified cross-modulation performance down to 87 dBµV at 40 dB AGC.
Technical Context
This device implements a dual-gate, single-channel-per-amplifier tetrode structure where Gate 1 (G1) serves as RF input control and Gate 2 (G2) acts as AGC voltage-controlled gain modulator. Each amplifier operates with independent source (S) and drain (D*, D**) terminals, enabling differential or isolated signal paths.
It supports DC-coupled biasing via external RG1 (100 kΩ typical), delivers stable transconductance (30 mS typ.) across 1–12 mA ID, and maintains sub-1.2 dB noise figure up to 800 MHz while sustaining >45 dB gain control range under VG2S = 0–4 V sweep.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS max | 8 V - sets maximum supply headroom for tuner LNA stages without breakdown risk |
| ID cont. | 20 mA per channel - defines usable bias current range for stable small-signal amplification |
| Noise figure | 0.7 dB typ. at 45 MHz - enables high-SNR reception in analog TV IF amplifiers |
| Power gain | 23 dB typ. at 800 MHz - provides sufficient RF gain for UHF tuner front-end cascading |
| Gain control range | 45 dB min. at 800 MHz - allows wide dynamic range compression in AGC loops |
| Cg1ss | 2.2 pF typ. - minimizes input loading on preceding mixer or filter stages |
| Rthchs | ≤280 K/W - ensures thermal stability in compact SOT363 tuner modules at 200 mW Ptot |
Pinout & Package
Package: SOT363 (SC-88), 6-pin plastic surface-mount package with exposed thermal pad (not electrically connected). Pin numbering follows JEDEC standard with 180° tape orientation option.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1*) | Amplifier A Gate 1 | RF input control terminal for channel A; requires DC blocking and impedance matching |
| 2 (G2) | Common AGC Gate | Shared gain-control input for both amplifiers; accepts 0–4 V AGC voltage |
| 3 (G1**) | Amplifier B Gate 1 | RF input control terminal for channel B; independent of G1* but same function |
| 4 (D**) | Amplifier B Drain | RF output node for channel B; connects to bandpass filter or IF transformer |
| 5 (S) | Common Source | Shared source node for both channels; must be AC-grounded via low-inductance path |
| 6 (D*) | Amplifier A Drain | RF output node for channel A; routed separately to avoid inter-channel coupling |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent amplifier channels | Enables simultaneous processing of main and diversity antenna signals in tuner ICs |
| Integrated gate protection diodes | Prevents ESD damage during board assembly without external clamping components |
| Low cross-modulation at gain reduction | Maintains 96 dBµV linearity at 10 dB AGC - critical for multi-channel analog TV coexistence |
| Pb-free RoHS-compliant construction | Meets automotive and consumer electronics environmental compliance requirements (AEC-Q101 qualified) |
| Thermal design support | Documented Rthchs ≤280 K/W enables accurate junction temperature estimation in dense tuner layouts |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BG5121KE6327HTSA1 | Higher 1.4 dB noise figure at 45 MHz; identical pinout and AGC range | Suitable for less demanding IF stages where SNR margin >3 dB is acceptable | Select when lower cost outweighs 0.7 dB NF advantage of BG5120K |
| BF998,115 | Single-channel dual-gate MOSFET; no integrated G2 sharing; 1.2 dB NF at 45 MHz | Requires discrete dual-device layout for two-channel operation | Choose only if board space permits duplication and thermal budget allows higher Ptot per channel |

FAQ
What is the maximum allowable gate-source voltage for BG5120KE6327HTSA1?
The absolute maximum gate-source voltage is ±6 V for both G1 and G2 terminals, as specified in the DC characteristics table. Exceeding this risks permanent gate oxide damage. Designers must ensure bias networks limit VG1S and VG2S within this range under all operating conditions, including power-up transients and ESD events.
Does BG5120KE6327HTSA1 require external gate protection diodes?
No - the device integrates internal gate protection diodes, eliminating the need for external ESD clamps. However, handling precautions for ESD-sensitive devices must still be observed during PCB assembly, and PCB layout should maintain short, low-inductance paths to ground for G1/G2 control lines.
Can BG5120KE6327HTSA1 operate with VG2S = 0 V for full gain mode?
Yes - applying VG2S = 0 V places the device in maximum gain state (Gp ≈ 30 dB at 45 MHz). The AGC characteristic curve confirms AGC = 45 dB at VG2S = 0 V, and the device remains stable with ID ≤ 12 mA under these conditions when biased with VDS = 5 V and RG1 = 100 kΩ.
Is the SOT363 package thermally enhanced?
The SOT363 package includes an exposed thermal pad that improves heat conduction from the die to the PCB. While not electrically active, proper soldering of this pad to a copper pour significantly reduces RthJA. Thermal resistance from channel to soldering point is specified as ≤280 K/W, confirming its suitability for continuous 200 mW operation in compact tuner modules.
