ATF-33143-TR1G

Overview

The ATF-33143-TR1G is a pseudomorphic high-electron-mobility transistor (pHEMT) manufactured by Broadcom Limited. It operates at a frequency of 2 GHz with an N-Channel configuration in an SOT-343 package. Key electrical parameters include a gain of 15 dB, a noise figure of 0.5 dB, and a P1dB compression point of 22 dBm. The device supports a maximum drain-source voltage of 5.5 V and a gate-source voltage of -5 V. Continuous drain current reaches 305 mA, while power dissipation is rated at 600 mW. Minimum forward transconductance is specified at 440 mmho, with a maximum operating temperature of +160°C.

Feature Summary

• Low noise figure for sensitive signal amplification
• High dynamic range performance
• Surface mount plastic packaging

Applications

• Low Noise Amplifier for Cellular/PCS Handsets
• LNA for WLAN, WLL/RLL, LEO, and MMDS Applications
• General Purpose Discrete PHEMT for Other Ultra Low Noise Applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for obsolete status as the product lifecycle may be discontinued. Ensure storage conditions meet moisture sensitivity level requirements before soldering.

Selection Notes

Compare noise figure and gain against system requirements. Evaluate thermal management capabilities given the 600 mW power dissipation rating. Verify compatibility with SOT-343 footprint constraints. Consider alternative pHEMT devices if higher current handling or different voltage ratings are needed.
