BFU710F,115

Overview

The BFU710F is an NPN silicon germanium microwave transistor designed for high-speed, low-noise applications. It utilizes 110 GHz fT technology and is housed in a plastic SOT343F package with reverse pinning and dual emitters. Key electrical parameters include a collector-base voltage of 10 V, a transition frequency of 43 GHz, and a maximum power gain of 14 dB at 12 GHz. The device achieves a noise figure of 1.45 dB at 12 GHz under specific bias conditions.

Feature Summary

• Utilizes 110 GHz fT silicon germanium technology for high-speed operation
• Features a plastic surface-mounted flat pack package with reverse pinning and dual emitter leads to minimize inductance
• Provides low noise performance suitable for sensitive RF front-end stages

Applications

• Second LNA stage and mixer stage in DBS LNBs
• Low noise amplifiers for microwave communications systems
• Ka band oscillators and DROs
• GPS receivers
• Bluetooth modules

Procurement Notes

Verify the component status on the official NXP website before design finalization, as product availability may change. Confirm that the SOT343F package variant matches the required reverse pinning configuration for PCB layout compatibility. Ensure ESD handling precautions are strictly followed during assembly and testing to prevent damage to the sensitive silicon germanium junctions.

Selection Notes

Select this transistor for designs requiring wideband performance up to Ka-band frequencies with minimal signal degradation. Evaluate the trade-off between bias current and noise figure, as lower currents optimize sensitivity while higher currents improve linearity and gain. Ensure the thermal management strategy accounts for the 136 mW total power dissipation limit relative to the solder point temperature.

Part Context

This component belongs to NXP's portfolio of silicon germanium RF transistors engineered for broadband wireless infrastructure. It serves as a specialized discrete solution for low-noise amplification where integrated MMICs may lack the necessary flexibility or specific gain characteristics for custom microwave circuit designs.
