BG20B

RF Amplifiers Overview

The BeRex Corp BG20B is an internally matched RF amplifier IC designed for intermediate frequency applications. It operates within a frequency range of 5MHz to 800MHz and provides a typical gain of 22dB with a noise figure of 4.6dB. The device features a P1dB output power of 21dBm and requires a supply voltage between 3.5V and 5.25V. Packaged in a compact SOT-89-3 surface-mount case, this component integrates matching networks to simplify circuit design for broadband RF signal amplification.

RF Amplifiers Procurement Notes

Verify the manufacturer marking code BIF1 on the component body to confirm authenticity. Ensure the package type matches the specified SOT-89-3 configuration. Cross-reference the part number against official BeRex Corporation documentation to validate electrical parameters such as gain and noise figure before integration into production designs.

RF Amplifiers Selection Notes

Select this component when internal matching is required to reduce board space and design complexity. The wide bandwidth supports multiple IF standards without retuning. Verify that the system supply voltage remains within the 3.5V to 5.25V operational window to ensure stable gain and linearity performance across the entire frequency range.

RF Amplifiers Part Context

The BG20B belongs to the BeRex Corporation family of internally matched RF amplifiers, which includes related models like the BG20A. These components are engineered for high-performance signal processing where size constraints and impedance matching simplicity are critical design drivers for modern electronic equipment.

RF Amplifiers Replacement Considerations

Public confirmed substitute part numbers are not available in verified documentation. Direct replacement should only be considered if the alternative component matches the exact pinout, SOT-89-3 package, and electrical specifications defined in the official datasheet.
