AT-30511-TR2G

Overview

The Broadcom Limited AT-30511-TR2G is an NPN silicon bipolar transistor housed in a SOT-143 surface-mount package. It is optimized for low voltage operation, specifically at 2.7 V and 1 mA bias current. At 900 MHz, the device provides a typical noise figure of 1.1 dB and associated gain of 16 dB. The collector-emitter breakdown voltage is rated at 5.5 V maximum, with a collector current limit of 8 mA and power dissipation of 100 mW. The component utilizes a self-aligned-transistor process with nitride passivation.

Feature Summary

• Optimized for high performance at low voltage and low current levels
• Features extremely fast switching with high gain capability
• Utilizes a five emitter finger interdigitated geometry

Applications

• Low Noise Amplifier (LNA) in wireless systems
• Gain stage and buffer circuits
• Oscillator and active mixer applications

Procurement Notes

Verify that the ordering suffix TR2G corresponds to the 13-inch tape-and-reel packaging containing 10,000 devices. Confirm the lead-free option is required by checking for the G suffix. Ensure the SOT-143 package dimensions match the target PCB footprint before finalizing procurement.

Selection Notes

Select this component when designing battery-powered wireless systems operating at 900 MHz, 1.8 GHz, or 2.4 GHz. The AT-30511 variant is preferred over the AT-30533 when higher associated gain is required due to its four-lead SOT-143 package configuration.

Part Context

This part belongs to the Agilent AT-3 series of high-performance NPN bipolar transistors. It shares the same die as the AT-30533 but utilizes the SOT-143 package instead of the SOT-23. The series is fabricated using a 10 GHz fT, 30 GHz fMAX self-aligned-transistor process.

Replacement Considerations

The AT-30533 serves as a functional alternative if the SOT-23 package is acceptable. Verify pinout compatibility between the SOT-143 and SOT-23 packages during substitution.
