The RA30H2127M is a 30-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 210- to 270-MHz range.
The RA30H2127M is a 30‑watt RF MOSFET amplifier module for mobile radios operating in the 210‑270 MHz band. It features enhancement‑mode MOSFET transistors, low‑power gate control (typical 1 mA at 5 V), and a compact 66 × 21 × 9.88 mm package.
The document provides maximum ratings, electrical characteristics, typical performance curves, mechanical drawing, test block diagram, and detailed recommendations for mounting, thermal design, ESD protection, and safety precautions.
| Frequency Range | 210‑270 MHz |
|---|---|
| Output Power | 30 W |
| Supply Voltage (Vpp) | 12.5 V |
| Gate Voltage Range | 0‑5 V |
| Typical Gate Current (Vg=5 V) | 1 mA |
| Module Size | 66 × 21 × 9.88 mm |
| Operating Temperature Range | -30 °C to +110 °C |
| Storage Temperature Range | -40 °C to +110 °C |
| Thermal Resistance (case‑air) for 30 W | 0.67 °C/W |
M3 screws should be tightened to a torque of 4.0 to 6.0 kgf‑cm.
A thermal resistance of about 0.67 °C/W (case‑air) is required to keep the case temperature below 90 °C.
The typical gate current at 5 V is 1 mA.
The module is sensitive to ESD voltages down to 1000 V, so appropriate ESD protection must be used.
