Product Overview
The RA07H4452M‑101 is Mitsubishi Electric two‑stage enhancement‑mode MOSFET RF power amplifier module for 12.5V portable UHF radio. Operating over 440‑520 MHz, it delivers >7W output with only 20 mW input drive. Integrated 50‑ohm I/O matching and VGG gate power control simplify RF design. The H2M metal‑ceramic flange‑mount module serves land mobile radio, walkie‑talkie and wireless telemetry systems.
Core Advantages
High‑Efficiency 7W RF Output
Delivers over 7W across 440‑520 MHz, drain efficiency >40% (typical 45%), suitable for battery‑powered portable radio equipment.
Built‑in 50‑Ohm Matching Network
Internal input‑output impedance matching removes external RF tuning parts and reduces PCB development workload.
VGG Gate‑Voltage Power Regulation
0‑5V gate voltage control supports APC automatic power adjustment for radio transmitter projects.
High VSWR Tolerance & Reliable Thermal Performance
Two‑stage MOSFET design with H2M metal‑ceramic package, stable performance under high‑duty‑cycle operation and load mismatch conditions.

Frequently Asked Questions
Q1: What frequency range does RA07H4452M‑101 support?
A: It works at 440 MHz‑520 MHz UHF band, designed for land‑mobile radio systems.
Q2: Are external 50‑ohm matching circuits required?
A: No. This module integrates 50‑ohm input & output matching, connects directly to 50‑ohm microstrip lines.
Q3: How to adjust output power for this amplifier module?
A: Adjust the VGG gate voltage within 0‑5 V. It supports APC automatic power‑control for transmitters.
Q4: What does suffix ‑101 stand for?
A: ‑101 indicates RoHS‑compliant variant. Base model RA07H4452M is pin‑to‑pin compatible but non‑RoHS.
Q5: Are there cross‑reference or alternative parts?
A: RA07H4047M‑101 is a similar 7 W Mitsubishi module for 400‑470 MHz. Not drop‑in replacement; re‑tuning is needed due to different frequency coverage.
Q6: Can it work for linear modulation besides FM?
A: Optimized for non‑linear FM modulation. Linear performance can be achieved by setting proper quiescent current via VGG.
Q7: Where can I get datasheet and technical documents?
A: Submit inquiry via our Quick Inquiry form for datasheet, application notes and volume quotation.
