MRF1550NT1

Overview

The MRF1550NT1 is an N-channel enhancement-mode lateral MOSFET designed for broadband commercial and industrial applications up to 175 MHz. It delivers 50 Watts output power with 14.5 dB gain and 55% efficiency at 12.5 Volts. The device operates across a 135-175 MHz band, withstands 20:1 VSWR under overdrive conditions, and features excellent thermal stability. It utilizes a TO-272-6 plastic package with lead-free terminations.

Feature Summary

• Broadband performance delivering full rated power across the 135-175 MHz frequency range
• High gain suitable for large-signal common source amplifier configurations
• Robust load handling capability capable of sustaining severe mismatch conditions without damage

Applications

• VHF and UHF mobile FM equipment power amplifiers
• Broadband commercial RF power amplification
• Industrial RF signal generation systems

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and lead-free termination specifications match project requirements. Ensure proper ESD handling protocols are followed during storage and assembly due to gate oxide sensitivity.

Selection Notes

Select this component for designs requiring high linearity and stable operation in VHF/UHF bands. Evaluate thermal management strategies carefully as the device dissipates significant power. Verify impedance matching networks align with provided series equivalent parameters for optimal performance.

Part Context

Originally manufactured by Freescale Semiconductor, this part belongs to the MRF1550 family of lateral RF power MOSFETs. The NT1 suffix indicates tape and reel packaging containing 500 units per reel. The device represents a transition point in NXP's portfolio following the acquisition of Freescale's semiconductor business.

Replacement Considerations

MRF1550FNT1 serves as a verified functional substitute within the same product family.
