ARF1500

Overview

The ARF1500 is an N-channel RF MOSFET manufactured by Microchip Technology, designed for high-power radio frequency applications. It operates at a test voltage of 125 V and supports a frequency of 27.12 MHz. The device delivers an output power of 750 W with a gain of 19 dB. It features a rated voltage of 500 V and a rated current of 60 A. The component is housed in a T-1 package.

Feature Summary

• N-channel RF MOSFET architecture optimized for high-frequency signal amplification
• Capable of delivering 750 W output power at 27.12 MHz operating frequency
• High gain performance of 19 dB under specified test conditions
• Robust voltage handling with 500 V rating and 125 V test voltage

Applications

• RF power amplification in broadcast transmission systems
• Industrial, Scientific, and Medical (ISM) equipment operating at 27.12 MHz
• High-power radio frequency signal generation circuits

Procurement Notes

Verify the specific datasheet revision and product change notifications (PCN) from Microchip Technology before integration. Confirm that the T-1 package dimensions and pinout match the design requirements. Ensure compliance with RoHS and REACH regulations as stated in the official documentation. Cross-reference the part number ARF1500 to avoid confusion with similar models like ARF1501 or ARF1505 which have different voltage ratings.

Selection Notes

Select the ARF1500 when a stable 750 W output is required at the standard 27.12 MHz frequency band. The 19 dB gain makes it suitable for stages requiring significant signal boosting. Consider the 500 V rated voltage for robustness against voltage spikes. Compare thermal management needs against the T-1 package capabilities. Evaluate if the 60 A rated current meets the circuit's peak demand without derating issues.

Part Context

The ARF1500 belongs to Microchip's portfolio of RF power MOSFETs, specifically utilizing Silicon VDMOS technology. It is distinct from higher-voltage variants like the ARF1505 (1200 V) and the ARF1501 (250 V). The T-1 package is a traditional ceramic-metal construction common in high-power RF transistors, facilitating efficient heat dissipation and reliable operation in demanding environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult Microchip Technology directly for qualified alternatives or cross-reference options based on specific electrical parameter tolerances.
