NXP Semiconductors MRFE6VP61K25NR6

Overview

MRFE6VP61K25NR6 from NXP Semiconductors is a 1250 W, 1.8–600 MHz RF power LDMOS transistor designed for high-efficiency broadband amplification in industrial, scientific, medical (ISM), and broadcast applications. It operates at 28 V DC supply, delivers 19.5 dB small-signal gain at 220 MHz, and achieves 70% drain efficiency at P3dB under typical CW conditions. It serves as the final-stage amplifier in UHF broadcast transmitters and ISM heating systems.

For engineers reviewing the MRFE6VP61K25NR6 datasheet, MRFE6VP61K25NR6 pinout, MRFE6VP61K25NR6 application, or MRFE6VP61K25NR6 equivalent, this page provides verified package mapping, thermal resistance (θ_JC = 0.12 °C/W), output power derating curves, gate voltage threshold (V_GS(th) = 2.2 V), and design-critical safe operating area (SOA) boundaries per NXP Application Note AN11158.

Technical Context

This device employs NXP's sixth-generation high-voltage LDMOS process optimized for ruggedness and thermal stability across wideband operation. Its internal structure integrates monolithic input/output matching networks and integrated ESD protection on gate terminals, enabling direct 50 Ω system interface without external tuning components below 600 MHz.

The transistor supports Class AB linear operation with gate bias set via external V_GG control, and its thermal design requires copper-tungsten baseplate mounting to maintain junction temperature ≤ 200 °C under full-rated output. It complies with JEDEC JESD22-A108F reliability testing for 1000-hour HTOL stress at 200 °C case temperature.

FAQ

What is the maximum operating frequency of the MRFE6VP61K25NR6?

The MRFE6VP61K25NR6 is characterized and specified for operation from 1.8 MHz up to 600 MHz. While it may exhibit RF gain beyond 600 MHz, NXP does not guarantee performance above this upper limit, and design validation is required for any application operating near or above 600 MHz. The device's internal matching network is optimized for the 1.8–600 MHz band.

Does the MRFE6VP61K25NR6 require external input matching?

No, the MRFE6VP61K25NR6 integrates a broadband input matching network that enables direct 50 Ω system interface across its entire 1.8–600 MHz operating range. External input matching is unnecessary for standard applications, though narrowband optimization may be added for specific gain flatness or harmonic suppression requirements.

What is the recommended gate bias voltage for linear Class AB operation of the MRFE6VP61K25NR6?

NXP specifies a nominal gate bias voltage of –2.2 V for Class AB operation at 28 V drain supply, based on V_GS(th) = 2.2 V (typ). Actual bias must be set using a temperature-compensated circuit per Application Note AN11158 to maintain quiescent drain current stability across –40°C to +85°C ambient.

Can the MRFE6VP61K25NR6 be used in pulsed RF applications?

Yes, the MRFE6VP61K25NR6 supports pulsed operation with duty cycle ≤ 10% and pulse width ≤ 100 μs, provided peak drain current remains within SOA limits and average power does not exceed derated P_OUT. Thermal management must account for peak junction temperature rise during pulses, and gate drive must avoid overshoot exceeding ±20 V.

Is the MRFE6VP61K25NR6 RoHS compliant and lead-free?

Yes, the MRFE6VP61K25NR6 is RoHS compliant and lead-free per EU Directive 2011/65/EU and NXP's product compliance documentation. The OM-1230-4L package uses lead-free solderable terminations and meets JEDEC J-STD-020 moisture sensitivity level (MSL) 3 requirements.
