Product Overview

The AFT05MS004NT1 is a high ruggedness N-channel enhancement-mode lateral MOSFET launched by NXP Semiconductors, specifically designed for handheld two-way radio applications. It operates in the frequency range of 136-941MHz with a 7.5V low-voltage supply and delivers stable output power above 4W. Featuring high gain, ultra-high drain efficiency and extreme VSWR tolerance, this device integrates ESD protection and stability enhancement modules, adopts SOT-89 package, and is suitable for power amplification requirements of VHF/UHF band handheld wireless devices, serving as the core power component for portable RF communication terminals .

Key Features

• Broadband Compatibility: Operating frequency covers 136-941MHz, supporting full-band VHF/UHF handheld radios without the need for frequency-specific component selection
• Ultra-High Energy Efficiency: Drain efficiency reaches 74.9% in 520MHz narrowband scenarios and remains above 61.8% in 136-174MHz broadband scenarios, significantly reducing device power consumption
• Extreme VSWR Tolerance: Withstands >65:1 VSWR at all phase angles in 435MHz band, with no device degradation under 3dB overdrive input, adapting to complex antenna matching environments
• Integrated Protection Design: Built-in ESD protection (1000V for human body model, 2000V for charge device model) and stability enhancement circuits, improving overall equipment reliability
• Low-Voltage Adaptation: Supports 7.5V low-voltage power supply, perfectly matching battery-powered handheld devices, and has excellent thermal performance (junction-to-case thermal resistance is only 4.4℃/W)

Technical Specifications

Typical Applications

• VHF Band Handheld Two-Way Radios: In the final-stage power amplification module of 136-174MHz VHF handheld radios, AFT05MS004NT1 can achieve 6W CW output power. The 17.8dB power gain reduces the pressure on the front-stage driver, the drain efficiency above 61.8% extends device battery life, and the >65:1 VSWR tolerance ensures communication stability in complex environments.
• UHF Band Portable Communication Terminals: For 350-520MHz UHF handheld devices, this device can maintain drain efficiency above 49.4% at 4W output power. The low thermal resistance of 4.4℃/W simplifies device heat dissipation design, and the integrated stability circuit avoids self-excitation risks during broadband operation, suitable for police and civilian UHF communication terminals.
• 700-800MHz Handheld Device Power Stage: In 700-800MHz band handheld communication devices, its broadband coverage eliminates the need for additional adaptive components, the low-voltage power supply characteristic matches the device lithium battery solution, and the extreme VSWR tolerance can cope with sudden situations such as device drops and poor antenna contact, ensuring uninterrupted communication links.
• 10-1000MHz RF Driver Stage: It can be used as a driver-stage device for 10-1000MHz medium and high-power RF systems. The high-gain characteristic reduces the power requirement for the front-stage signal source, the integrated ESD protection improves the yield of production line assembly, and the broadband impedance characteristic simplifies the design of multi-band matching circuits.

Why Choose AFT05MS004NT1 ?
