Product Overview
MRF150 is N‑channel enhancement‑mode RF power TMOS MOSFET for transmitters up to 150 MHz. Operating at 50 V, it provides 150 W PEP output power, featuring high efficiency, low IMD and 30:1 VSWR ruggedness. The flanged Case 211‑11 Style 2 ceramic package delivers reliable thermal performance for CW and SSB RF power amplifiers.
Core Advantages
High RF Performance
12‑17 dB gain, 150 W PEP output at 50 V, lowering drive‑power requirements for transmitter systems.
Superior Mismatch Resistance
Factory‑validated for 30:1 full‑power VSWR tolerance across all phase angles.
Good Linearity
Low intermodulation distortion, ideal for linear SSB high‑power amplifier designs.
Robust Thermal Package
Case 211‑11 Style 2 flange‑mount ceramic housing enables effective heat dissipation for continuous high‑power operation.

Frequently Asked Questions
Q1: What is the output power and operating voltage of MRF150?
A: MRF150 outputs 150W PEP at 50V nominal supply, max frequency 150 MHz. This is PEP peak‑envelope power, not continuous CW power.
Q2: How rugged is MRF150 against load mismatch?
A: 100% factory‑tested to survive 30:1 VSWR across all phases under full rated power.
Q3: What package does MRF150 use?
A: Case 211‑11 Style 2 flanged ceramic package, market alias M174. Requires chassis flange mounting.
Q4: What is the difference between MRF150 and MRF151G?
A: MRF150:150W PEP up to 150MHz; MRF151G:300W PEP up to 175MHz. Pin‑out incompatible, no direct drop‑in replacement, matching circuit needs redesign.
Q5: Are there pin‑compatible cross‑reference parts?
A: No guaranteed drop‑in alternative. Any candidate replacement requires full lab validation before production use.
Q6: Does MRF150 have suffix or tape‑reel variants?
A: MRF150 is flange‑mount through‑hole device, no SMD tape‑reel suffix versions.
Q7: Is MRF150 ESD‑sensitive?
A: Yes. ESD anti‑static protection must be applied during handling and assembly.
Q8: How to get datasheet, CAD files or volume pricing?
A: Submit quick inquiry for datasheets, CAD models, stock status and bulk quotation.
