BGR405H6327XTSA1

Overview

The BGR405H6327XTSA1 is an NPN silicon RF transistor with integrated bias circuitry, manufactured by Infineon Technologies. It operates in the SOT-343 package and utilizes the SIEGET 25 GHz fT-Line technology. The device features a typical bias current of 0.85 mA at VCC = 1.2V. Key electrical parameters include an insertion power gain (S21) of 7.5 dB at 0.4 GHz and 7.0 dB at 1.8 GHz. The noise figure (NF) is typically 1.0 dB at 0.4 GHz and 1.6 dB at 1.8 GHz. Reverse isolation (S12) measures -37 dB at 0.4 GHz and -25 dB at 1.8 GHz. The output third-order intercept point (OIP3) is 14.5 dBm at 1.8 GHz with VCC = 4V.

Feature Summary

• Integrated on-chip bias circuitry providing a stable 0.85 mA bias current at 1.2V supply voltage.
• Monolithic design combining an NPN silicon RF transistor with internal resistors for simplified amplifier implementation.
• Utilizes SIEGET 25 GHz fT-Line technology for high-frequency performance.

Applications

• Low Noise Amplifiers (LNAs)

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as datasheet revision dates may indicate obsolescence. Ensure handling precautions are observed due to electrostatic discharge sensitivity. Validate package marking AVS against physical units received.

Selection Notes

Select this component for applications requiring low noise figures around 0.4 GHz and 1.8 GHz frequencies. Consider the integrated bias circuitry to reduce external component count. Verify that the SOT-343 footprint matches the PCB layout requirements. Check thermal resistance limits if operating near maximum junction temperatures.

Part Context

This part belongs to the BGR series of RF transistors with built-in bias networks. It shares the SOT-343 package form factor common to many small-signal discrete components from Infineon. The H6327 suffix typically denotes specific tape and reel packaging configurations used in surface mount assembly lines.

Replacement Considerations

Direct pin-compatible replacements within the same family should be verified against electrical specifications. Alternative devices must match the SOT-343 outline dimensions and maintain similar noise figure and gain characteristics at target frequencies.
