Infineon Technologies BG3130E6327HTSA1

Overview

BG3130E6327HTSA1 from Infineon Technologies is a dual N-channel MOSFET tetrode designed for UHF/VHF tuner front-ends in analog TV systems (NTSC/PAL), integrating two AGC-controlled amplifiers in one SOT363 package with 8 V V_DS, 25 mA I_D, and 1.9 pF C_g1ss. It delivers 24 dB power gain at 800 MHz and 1.3 dB noise figure at same frequency.

For engineers reviewing the BG3130E6327HTSA1 datasheet, BG3130E6327HTSA1 pinout, BG3130E6327HTSA1 application, or BG3130E6327HTSA1 equivalent, key selection criteria include dual-gain-control capability, integrated ESD protection diodes, cross-modulation performance under AGC (90–100 dBµV), and thermal resistance ≤280 K/W for compact tuner designs.

Technical Context

This tetrode implements two independent N-channel JFET amplifier stages sharing a common source terminal, where Gate 1 controls channel conduction and Gate 2 serves as AGC input. Its structure enables simultaneous RF amplification and automatic gain control without external coupling networks.

It operates with V_G2S = 0–4 V for gain control range of 45 dB at 800 MHz, while maintaining low noise (1.3 dB typ.) and high linearity (cross-modulation ≥90 dBµV at AGC = 0 dB). Pin configuration supports separate RF input (G1), RF output (D*), and AGC bias (G2) routing in space-constrained tuner modules.

FAQ

What is the maximum operating frequency for stable gain in BG3130E6327HTSA1?

The device is characterized for stable power gain up to 800 MHz (24 dB typ.), with verified performance at 45 MHz (31 dB) and usable response beyond 1 GHz. Gain rolls off above 1 GHz due to parasitic capacitance; design margin requires layout optimization below 900 MHz for production use.

How does the dual-gate structure enable AGC without external components?

Gate 2 (Pin 2) acts as a depletion-mode control electrode: varying V_G2S from 0 to 4 V modulates channel conductivity independently of Gate 1, directly attenuating RF gain by up to 45 dB without resistive dividers or op-amps. This is intrinsic to the tetrode's vertical channel geometry.

Is BG3130E6327HTSA1 RoHS-compliant and halogen-free?

Yes - manufactured per Infineon's 2005 specification, it meets RoHS Directive 2002/95/EC and contains no brominated flame retardants or chlorine-based solvents. Full material declaration is available under Infineon document ID 01_01_01_BG3130E6327HTSA1.

Can Pin 5 (S) be connected to PCB ground plane without degrading RF performance?

Yes - Pin 5 is the common source terminal and must be tied to RF ground via shortest possible path. The SOT363 package includes an exposed thermal pad (connected internally to source) that should be soldered to a solid ground plane for optimal thermal dissipation and impedance stability at UHF frequencies.
