Product Overview
The RA07M3847M‑501 is high‑efficiency N‑channel MOSFET RF power amplifier module by Mitsubishi Electric for 378‑470MHz UHF band. Designed for 7.2V portable two‑way radios, it outputs over 7W with 50mW input drive. Integrated 50Ω input/output matching removes external matching circuits. Supports VGG gate voltage for APC automatic power control. H46S flange‑mount package delivers good thermal performance for handheld & portable communication equipment.
Core Advantages
High Efficiency & 7W+ Output Power
Deliver 7W+ RF output power across full 378‑470MHz band, drain efficiency min 40%, typical 48‑50%, extend battery working time for portable radio devices.
Built‑in 50‑Ohm Internal Matching
RF input & output ports internally matched to 50Ω, reduce external peripheral components, simplify PCB layout design.
VGG Gate Voltage APC Power Adjustment
0‑3.5V gate control voltage supports APC loop, realize continuous output‑power adjustment.
H46S Flange Screw Mount Package
Flange screw mounting for excellent heat dissipation, fit for 7.2V lithium‑battery powered portable radio systems.

Frequently Asked Questions
Q1: What is the operating frequency of RA07M3847M‑501?
A: 378‑470 MHz UHF frequency band.
Q2: Do I need external 50‑ohm matching circuit?
A: No. Input and output are internally 50Ω matched, simplifies RF PCB design.
Q3: What does suffix ‑501 stand for?
A: ‑501 = RoHS lead‑free version. Base model RA07M3847M is non‑RoHS. Pin‑to‑pin fully interchangeable, same H46S package.
Q4: Can RA07M3843M replace RA07M3847M‑501?
A: Pin‑compatible. RA07M3843M works 378‑430 MHz. It can substitute only below 430 MHz, cannot support 430‑470 MHz.
Q5: Are there other H46S‑package compatible alternatives?
A: RA07M4452M‑501；7.2V /7W output, frequency 440‑520 MHz, pin‑compatible for higher‑UHF projects.
Q6: What is maximum supply voltage VDD?
A: Nominal 7.2V, absolute maximum 12V. Do not run continuously above 9.2V.
Q7: Any special requirement for H46S mounting?
A: H46S flange‑screw module. Must screw tightly onto heatsink for heat dissipation, cannot rely only on SMD reflow soldering.
Q8: What should I notice when purchasing?
A: Confirm full part number including suffix ‑501 for RoHS‑compliant stock.
Q9: How can I get datasheet and bulk price?
A: Submit product inquiry for official datasheet, reference schematic and volume quotation.
