ABA3100S3TR

Overview

The ABA3100S3TR is a monolithic balanced low noise linear amplifier integrated circuit manufactured by Anadigics, Inc. Designed for high linearity applications, this device operates within a frequency range of 50 MHz to 1 GHz. It utilizes a 16-SOIC surface mount package with a width of 3.90 mm. The component requires a supply voltage between 4.5 V and 9 V and draws a supply current of 150 mA. It is engineered for use in cellular telephone base station driver stages and other RF systems requiring precise signal amplification.

Feature Summary

• Balanced architecture providing enhanced linearity and noise performance
• Monolithic construction suitable for high-frequency RF applications
• Surface mount packaging for automated assembly integration

Applications

• Cellular Telephone Base Station Driver
• RF Signal Amplification Systems
• High Linearity Communication Equipment

Procurement Notes

Verify the manufacturer designation as Anadigics, Inc., noting that Skyworks Solutions may also list this part due to corporate acquisition history. Confirm the specific suffix S3TR corresponds to the 16-SOIC tape and reel configuration. Ensure the operating voltage range matches system requirements of 4.5 V to 9 V. Check for RoHS compliance status as historical data varies. Validate the frequency range specification against the specific datasheet revision prior to procurement.

Selection Notes

Select the ABA3100S3TR when designing circuits requiring a balanced low noise amplifier for frequencies up to 1 GHz. This component is appropriate for base station driver applications where high linearity is critical. Consider the 16-SOIC package dimensions for PCB layout constraints. Ensure the power supply can deliver the required 150 mA current at voltages between 4.5 V and 9 V. Compare performance metrics against alternative MMICs if wider bandwidth or different gain specifications are needed.

Part Context

The ABA3100 series represents a family of balanced linear amplifiers from Anadigics, later absorbed by Skyworks Solutions. Variants such as ABA3100RS3P1 and ABA3100S3P0 share similar core functionalities but differ in packaging and specific electrical characteristics. The ABA3100S3TR specifically denotes the surface mount version intended for high-volume manufacturing. This component belongs to the broader category of RF and microwave monolithic microwave integrated circuits (MMICs) used in telecommunications infrastructure.

Replacement Considerations

Public confirmed substitute part numbers include ABA3100RS3P1 and ABA3100S3P0 from Skyworks Solutions Inc. These variants maintain the 1 GHz balanced low noise linear amplifier functionality. Verify pinout compatibility and thermal requirements when substituting. Cross-reference datasheets to ensure equivalent linearity and noise figures for the specific application environment.
