Product Overview
The MRF1508T1 is N‑channel enhancement‑mode LDMOS RF power transistor from NXP (Freescale). Optimized for 7.5V‑12.5V low‑voltage operation up to 520 MHz, it delivers 8W output power with 11.5dB gain and 55% efficiency. Packaged in PLD‑1.5 (SOT‑4651 / CASE 466‑02) SMD housing, it is widely used for VHF/UHF handheld & mobile land‑mobile radio amplifiers.
Core Advantages
High Gain & Efficiency
11.5 dB typical gain and 55% PAE, lower power consumption for portable radio devices.
Dual‑Voltage Support
Works at 7.5V for handheld radios and 12.5V for vehicle‑mount mobile transceivers.
Excellent Ruggedness
Strong VSWR mismatch resistance, stable performance under real‑world antenna load variation.
SMD Compact Package
PLD‑1.5 surface‑mount package, easy SMT assembly and saves PCB layout space.

Frequently Asked Questions
Q1: What does the “T1” suffix mean in MRF1508T1?
A: “T1” stands for 7‑inch tape‑and‑reel for automatic SMT assembly. Base part MRF1508 is tray bulk version without tape‑reel packaging.
Q2: What frequency and output power for MRF1508T1?
A: It targets VHF/UHF up to 520 MHz, typical 8W RF output power under 7.5V supply condition.
Q3: What drain supply voltage can I use?
A: Dual‑supply support: 7.5V for handheld radio, 12.5V for vehicle‑mount radio. Do not exceed 25V maximum drain‑source voltage.
Q4: Are there pin‑compatible alternative parts?
A: MRF1511T1 (10W) and MRF1517T1 (15W) share the same PLD‑1.5 package footprint. They are series variants with higher power, require input/output matching re‑tuning, not direct drop‑in replacement.
Q5: Can I replace it with other‑brand RF LDMOS?
A: No true cross‑brand pin‑to‑pin equivalent. Different die and package parasitics require full re‑optimization of matching circuit for gain, efficiency and VSWR performance.
Q6: What is the difference between CASE 466‑02, PLD‑1.5 and SOT‑4651?
A: All refer to identical 4‑pin SMD package. CASE 466‑02 is Freescale internal code; PLD‑1.5 is marketing name; SOT‑4651 is JEDEC standard designation.
Q7: How to get datasheet, reference design or bulk quotation?
A: Submit inquiry via our quick inquiry form. Our sales & RF engineering team will reply within 24 hours with datasheets, reference layouts and volume pricing.
