ARF466FL

Overview

The ARF466FL is an RF MOSFET transistor manufactured by Microchip Technology. It operates at a test voltage of 150 V and delivers an output power of 150 W. The device is designed for operation at a frequency of 40.68 MHz, providing a gain of 16 dB. It features a rated voltage of 1000 V and a rated current of 13 A. The component utilizes N-channel MOS technology and is housed in a T3 package.

Feature Summary

• Designed for high-frequency RF applications with specified gain characteristics
• Capable of delivering substantial output power within its operational voltage range
• Utilizes silicon-based N-channel MOSFET technology for robust performance

Applications

• RF power amplification circuits
• Industrial, Scientific, and Medical (ISM) radio frequency equipment
• High-power RF signal generation systems

Procurement Notes

Verify the specific suffix FL against official Microchip documentation to confirm pinout and electrical tolerances. Ensure compatibility with existing thermal management solutions due to the power rating. Confirm RoHS status as indicated in manufacturer records, noting potential regulatory differences compared to standard compliant variants. Validate package dimensions against PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring 150 W output power at 40.68 MHz. Consider the 150 V test voltage and 1000 V rated voltage limits during biasing design. The T3 package dictates specific mounting and thermal dissipation strategies. Evaluate the 16 dB gain requirement against system noise figure constraints to ensure adequate signal amplification without excessive distortion.

Part Context

The ARF466 belongs to Microchip's portfolio of RF power MOSFETs. This series targets high-efficiency amplification in industrial and scientific bands. The ARF466FL variant specifically denotes the 150 V test voltage configuration within the broader ARF466 family, distinguishing it from higher voltage counterparts like the ARF466AG which supports significantly higher voltage ratings.

Replacement Considerations

Consult Microchip datasheets for direct cross-references within the ARF466 series. Verify that substitute parts match the 150 W power output and 40.68 MHz frequency specifications. Ensure the replacement maintains the T3 package form factor or requires mechanical adaptation.
