Product details
Overview
BG3430RH6327XTSA1 from Infineon Technologies is a dual N-channel MOSFET tetrode designed for input stages of dual-band TV/radio tuners, integrating two AGC amplifiers in one SOT-363 package with shared source and gate-2 pins, 8 V VDS, 25 mA ID, and 1.3 pF Cdss at 10 MHz.
For engineers reviewing the BG3430RH6327XTSA1 datasheet, BG3430RH6327XTSA1 pinout, BG3430RH6327XTSA1 application in tuner front-ends, or BG3430RH6327XTSA1 equivalent for AGC amplifier replacement, key selection factors include dual-amplifier integration, 45 dB gain control range at 800 MHz, cross-modulation performance under 105 dBµV at 40 dB AGC, and RoHS-compliant AEC-Q101 qualification.
Technical Context
This device implements a monolithic dual-gate FET architecture where Amp A and Amp B share the source (Pin 2) and gate-2 (Pin 5), enabling independent gain control via separate gate-1 inputs (Pin 1 and Pin 6). Internal switching logic toggles amplifier activation based on VGG voltage level: 5 V enables Amp A while disabling Amp B, and 0 V reverses the state.
Each amplifier features fully or partially integrated bias networks - Amp B's is fully integrated, Amp A's is partially integrated - reducing external component count. The on-chip gate protection diodes and ESD-sensitive handling requirement (HBM >2 kV per AEC-Q101) reflect its use in RF front-end signal chains requiring robust transient immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 8 V - maximum drain-source blocking voltage, defining safe RF signal swing headroom in tuner input stages |
| ID | 25 mA - continuous drain current limit, constraining usable bias point for stable small-signal amplification |
| gfs | 33 mS typical - forward transconductance at 5 V VDS/4 V VG2S, directly determining small-signal gain and linearity |
| F | 1.3 dB typical at 800 MHz - noise figure specifying minimum added noise in high-frequency receiver front-ends |
| ∆Gp | 45 dB - gain control range over 0–4 V VG2S, enabling wide-dynamic-range AGC without external attenuators |
| Cdss | 1.3 pF - output capacitance at 10 MHz, critical for impedance matching and stability in 45–800 MHz tuner bands |
| Xmod | ≤105 dBµV at 40 dB AGC - measured cross-modulation under 1% k-factor, quantifying intermodulation distortion suppression |
Pinout & Package
Package: SOT-363 (SC-88), 6-pin plastic surface-mount package, lead-free (RoHS compliant), qualified per AEC-Q101.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1A) | Gate 1 of Amplifier A | Primary RF gain control input for Amp A; referenced to shared source (Pin 2); requires external bias network |
| 2 (S) | Source (common to both amplifiers) | Shared AC/DC reference node for both FETs; connects to ground plane in tuner PCB layout |
| 3 (D*) | Drain of Amplifier A | RF output node for Amp A; routed to first IF stage or mixer input |
| 4 (D**) | Drain of Amplifier B | RF output node for Amp B; isolated routing required to prevent coupling between bands |
| 5 (G2) | Common Gate 2 (AGC control) | Global gain reduction control line for both amplifiers; driven by tuner AGC voltage (0–4 V) |
| 6 (G1B) | Gate 1 of Amplifier B | Primary RF gain control input for Amp B; internally biased; no external resistor needed |
Key Features

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 |
|---|---|---|---|
| BGA3430 | Same die, identical electrical specs, but in SOT-363 with different tape orientation (180° rotated loading) | No functional difference; only affects automated pick-and-place reel setup | Select when using legacy feeder configurations requiring reversed tape direction |
| BF998 | Single dual-gate MOSFET (not dual-amplifier), higher VDS (12 V), no integrated switch or shared G2 | Requires external switching logic and dual bias networks; lacks built-in AGC coordination | Choose only if redesigning for discrete flexibility and higher voltage margin |
Compared with BGA3430, BG3430RH6327XTSA1 offers identical RF performance but differs in reel packaging orientation; versus BF998, it delivers integrated dual-amplifier operation with coordinated AGC, reducing bill-of-materials and layout complexity at the cost of fixed topology.

FAQ
What is the function of Pin 5 (G2) in the BG3430RH6327XTSA1?
Pin 5 (G2) serves as the common AGC control gate for both amplifiers. Applying 0 V disables Amplifier A and enables Amplifier B, while 5 V reverses the state. It is not a signal input but a digital-like control line that reconfigures internal conduction paths without requiring external switching transistors.
Can BG3430RH6327XTSA1 operate with VDS = 12 V?
No. The absolute maximum VDS rating is 8 V. Exceeding this risks irreversible avalanche breakdown. Although V(BR)DS is specified at 12 V under pulsed test conditions (ID = 100 µA), continuous operation above 8 V violates the maximum rating and voids AEC-Q101 qualification.
Is external gate protection required despite on-chip diodes?
On-chip gate protection diodes suffice for standard ESD events per AEC-Q101, but external 100 Ω series resistors on G1 pins are recommended for sustained RF overdrive or lightning-induced surges beyond HBM 2 kV. Layout must maintain short, low-inductance paths to ground.
How does cross-modulation performance vary with AGC level?
Cross-modulation degrades as AGC increases: Xmod = 90 dBµV at 0 dB AGC, 93 dBµV at 10 dB AGC, and 105 dBµV at 40 dB AGC. This reflects progressive compression of the active channel, confirming the device's suitability for applications requiring ≤40 dB AGC depth with controlled distortion.
