AT-32032-TR1

Overview

The AT-32032-TR1 is a silicon NPN RF bipolar transistor manufactured by Broadcom Limited. It operates at a frequency of 2.4 GHz with a minimum DC current gain (hFE) of 70. The device supports a maximum collector-emitter voltage (VCEO) of 5.5 V and an emitter-base voltage (VEBO) of 1.5 V. Continuous collector current is rated at 40 mA, with power dissipation of 200 mW. It is housed in an SOT-323 surface-mount package and functions as a single transistor within a temperature range of -65°C to +150°C.

Feature Summary

• Designed for low-current RF applications operating at 2.4 GHz
• Utilizes silicon technology for stable performance across wide temperature ranges
• Packaged in compact SOT-323 surface-mount format for space-constrained designs

Applications

• RF signal amplification in wireless communication modules
• Low-noise amplifier stages in 2.4 GHz transceivers
• Signal conditioning in consumer electronics with Bluetooth or Wi-Fi capabilities

Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS compliance status via official documentation before integration. Check for end-of-life notices or product change notifications from the manufacturer to ensure long-term supply stability for production cycles.

Selection Notes

Select this component when designing circuits requiring NPN bipolar transistors optimized for 2.4 GHz operation. Ensure the design accommodates the 5.5 V voltage limit and 40 mA current rating. Verify that the SOT-323 footprint matches the PCB layout requirements and thermal management strategy for 200 mW dissipation.

Part Context

This part belongs to Broadcom's portfolio of RF discrete semiconductors. It is distinct from optocouplers like the HCPL series also listed in supplier catalogs. The TR1 suffix typically indicates tape-and-reel packaging, differentiating it from bulk-packaged variants such as the BLKG version of the same electrical specification.

Replacement Considerations

The AT-32032-BLKG shares identical electrical specifications but differs in packaging type. No other direct substitutes are confirmed in public documentation. Evaluate pin-compatible alternatives only if the original is unavailable, ensuring frequency and gain parameters remain consistent.
