RF Amplifiers Procurement Notes

Verify the specific datasheet revision and package marking (BG) against official BeRex documentation before procurement. Ensure the supplier provides original components with traceable manufacturing records. Confirm that the received units match the BG18A designation and SOT-89-3 package specifications to avoid counterfeit or substituted parts.

RF Amplifiers Selection Notes

Select the BG18A when a cascadeable, internally matched gain block is required for frequencies up to 4 GHz. Its temperature-compensated design makes it suitable for environments with significant thermal fluctuations. Consider this component for multi-stage amplifier designs where consistent impedance matching and gain stability are critical for system performance.

RF Amplifiers Part Context

The BG18A belongs to BeRex Corporation's BG series of RF amplifiers, which includes variants such as BG18B, BG18C, and BG18D. These components share similar InGaP HBT technology and frequency ranges but may differ in specific electrical characteristics or package configurations. The series is designed for versatile use in modern wireless communication infrastructure.

RF Amplifiers Replacement Considerations

Direct substitutes within the same family include BG18B, BG18C, and BG18D. Verify compatibility by comparing specific electrical parameters and pin configurations in the respective datasheets. Other models like BG17A or BG13B may serve as alternatives if their frequency ranges and gain requirements align with the application needs.
