Product details
Overview
BG3230 E6327 from Infineon Technologies is a dual N-channel MOSFET tetrode designed for low-noise AGC amplifier stages in UHF/VHF tuners operating at 5 V supply. It integrates two independent amplifiers (A and B), stabilized bias networks, gate protection diodes, and delivers 33 mS forward transconductance, 1.9 pF gate1 input capacitance, and 24–31 dB power gain at 45–800 MHz.
For engineers reviewing the BG3230 E6327 datasheet, BG3230 E6327 pinout, BG3230 E6327 application in tuner front-ends, or BG3230 E6327 equivalent for dual AGC amplifier replacement, this device offers verified cross-modulation suppression (≥90 dBµV at 40 dB AGC), 1.3–1.7 dB noise figure at 45/800 MHz, and integrated ESD protection per gate.
Technical Context
This dual-gate MOSFET operates as two independent RF amplifiers sharing a common source terminal (Pin 5), with Gate 1 (Pins 1 & 6) serving as RF input and Gate 2 (Pin 2) controlling gain via AGC voltage. Each amplifier features self-biasing capability (IDSO = 13 mA typ.) and exhibits strong gain control range (∆Gp ≥ 45 dB) across 0–4 V VG2S.
The device uses a tetrode structure enabling high isolation between input (G1) and control (G2) terminals, minimizing feedthrough and supporting stable gain compression. Its SOT363 package supports compact tuner module layouts, and thermal resistance Rthchs ≤ 280 K/W ensures reliable operation under continuous 200 mW dissipation limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Drain-source voltage (VDS) | 8 V - Maximum DC blocking voltage across each channel; defines safe RF signal swing headroom. |
| Forward transconductance (gfs) | 33 mS typ. - Directly determines small-signal voltage gain (Av ≈ gfs × RL) in 50 Ω systems. |
| Noise figure (F) | 1.3–1.7 dB @ 45/800 MHz - Enables high-sensitivity reception in digital TV and FM radio front-ends. |
| Gain control range (∆Gp) | ≥45 dB - Allows wide dynamic range AGC without external attenuators or switching. |
| Cross-modulation (Xmod) | 90–100 dBµV @ AGC = 40 dB - Confirms robust intermodulation rejection in multi-channel broadcast environments. |
| Total power dissipation (Ptot) | 200 mW - Sets maximum combined RF + DC power handling per package; derates linearly above 100°C. |
| Gate1 input capacitance (Cg1ss) | 1.9 pF - Matches standard 50 Ω input impedance at UHF frequencies with minimal matching network complexity. |
Pinout & Package
SOT363 (SC-88) surface-mount package: 6-pin, 2.1 mm × 1.25 mm footprint, 0.65 mm pitch, tape-and-reel compatible (3,000 pcs/reel ø180 mm). Pin 1 marked with dot; 180° rotated tape loading available.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6 | Gate 1 (Amp A / Amp B) | RF input terminals - isolated high-impedance inputs for separate signal paths; require DC blocking caps. |
| 2 | Gate 2 (common) | AGC control voltage input - adjusts gain of both amplifiers simultaneously; 0–4 V range yields ≥45 dB control. |
| 3, 4 | Drain (Amp A / Amp B) | RF output nodes - each drives 50 Ω load; layout must minimize parasitic inductance for UHF stability. |
| 5 | Source (common) | Shared AC/DC return path - connects to ground plane; critical for gain consistency and noise coupling control. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent amplifier channels | Enables simultaneous processing of two RF signals (e.g., diversity reception or dual-band tuning) in one footprint. |
| Integrated gate protection diodes | Provides ESD immunity up to ±1 kV HBM without external clamps - reduces BOM count and PCB area. |
| Stabilized internal bias network | Eliminates need for external bias resistors; ensures consistent IDSO = 13 mA typ. across temperature and process variation. |
| Low 1.9 pF Cg1ss and 1.1 pF Cdss | Minimizes capacitive loading on preceding stages and enables broadband matching up to 800 MHz. |
| Verified cross-modulation performance | Guarantees ≥90 dBµV suppression at 40 dB AGC - meets stringent DVB-T and ATSC tuner linearity requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-gate AGC amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BFP181W | Single-channel NPN RF transistor; higher fT (8 GHz), no integrated AGC control; requires external bias network. | Used in discrete high-gain LNA designs where gain control is implemented separately (e.g., PIN diode attenuator). | Select when absolute minimum noise figure (<1.0 dB) is required and board space allows discrete AGC implementation. |
| BF998 | Dual-gate MOSFET in SOT143 package; lower gfs (20 mS), wider VDS rating (12 V), but no integrated gate protection diodes. | Common in legacy analog TV tuners; lacks ESD hardening needed for modern automated assembly lines. | Choose only for cost-sensitive replacements in non-automated production where external ESD protection is already present. |
Compared with BFP181W and BF998, BG3230 E6327 uniquely combines dual-channel integration, on-chip AGC control, gate protection diodes, and verified cross-modulation performance - reducing component count and improving production yield in tuner modules.

FAQ
What is the recommended PCB layout practice for BG3230 E6327 to maintain UHF stability?
Use solid ground plane beneath the SOT363 footprint with minimal thermal relief on Pin 5 (source); keep RF traces short and 50 Ω controlled impedance; place 4.7 nF DC-blocking caps within 2 mm of Pins 1/6; avoid vias near drain pins (3/4) to prevent inductance-induced oscillation above 500 MHz.
Can BG3230 E6327 operate with VG2S beyond 4 V for extended AGC range?
No - VG2S must remain within ±6 V absolute maximum rating, but gain control saturates above 4 V. Exceeding 4 V provides no additional attenuation and risks increased leakage current (±IG2SS ≤ 50 nA max), degrading noise figure and cross-modulation performance.
Is BG3230 E6327 qualified for lead-free reflow soldering?
Yes - the SOT363 package is rated for JEDEC J-STD-020D-compliant lead-free reflow profiles (peak 260°C, 10 sec max). Thermal resistance Rthchs ≤ 280 K/W ensures junction temperature remains below 150°C during standard 20-second profile exposure.
How does the common-source configuration affect inter-channel isolation in BG3230 E6327?
Pin 5 (common source) creates ~35 dB inter-channel isolation at 45 MHz and ~25 dB at 800 MHz due to shared substrate coupling. For >40 dB isolation, use separate ground vias under each amplifier section and isolate source copper pours with narrow slots aligned between Pins 3 and 4.
