BGB 540 E6327

Overview

The BGB 540 E6327 is an active biased RF transistor MMIC manufactured by Infineon Technologies. It utilizes SIEGET-45 technology and features an integrated biasing circuit for high gain and low noise figure applications. The device operates with a typical supply voltage range of 1.4V to 4.3V. Key electrical characteristics include a maximum stable power gain of 18dB at 1.8GHz, a noise figure of 1.15dB at 0.9GHz, and a collector current capability of up to 80mA. The component is housed in a compact SOT-343 package.

Feature Summary

• Integrated biasing circuit allows collector current control via external resistor
• High gain performance suitable for low noise amplifier designs
• Compact SOT-343 surface mount package

Applications

• High gain low noise amplifiers
• Wideband cellular phone circuits
• Cordless telephone systems
• SAT-TV receivers
• High frequency oscillators

Procurement Notes

Verify the specific ordering suffix E6327 against official Infineon documentation to confirm packaging details such as reel or cut tape specifications. Confirm that the component status remains active for new designs, as availability may vary by region. Ensure compliance with CECC manufacturing standards if required for your specific application environment.

Selection Notes

Select this component when designing circuits requiring simplified biasing networks for RF amplification. The internal bias structure reduces external component count compared to discrete transistors. Verify that the operating frequency range aligns with the specified S-parameter data, particularly for applications below 3GHz where matching networks are critical.

Part Context

This part belongs to the BGB series of active biased RF transistors from Infineon Technologies. It is designed specifically for wireless communication applications where space constraints and power efficiency are priorities. The integration of biasing components within the MMIC distinguishes it from standard discrete NPN transistors like the BFP540.

Replacement Considerations

Discrete NPN transistors require external biasing networks which increase board space. If replacing with another MMIC, verify pin compatibility and ensure the substitute supports similar gain and noise figures at the target operating frequencies.
