The RA13H8891MB is a 13-watt RF MOSFET amplifier module for 12.5-volt mobile radios that operate in the 880- to 915-MHz range.
The RA13H8891MB is a 13‑watt RF MOSFET power‑amplifier module designed for 12.5‑V mobile radios operating in the 880‑915 MHz band. It features enhancement‑mode MOSFET transistors, low‑power gate control (typical 1 mA at 5 V), and a compact 60.5 × 14 × 6.4 mm package.
The document lists maximum ratings, electrical characteristics, typical performance curves, and detailed mechanical recommendations. It includes mounting instructions, heat‑sink requirements, ESD precautions, and safety notices, as well as RoHS compliance information.
| Frequency range | 880‑915 MHz |
|---|---|
| Output power | 13 W |
| Drain voltage rating (Vpp) | 17 V |
| Input power rating | 5 mW |
| Typical total efficiency | 35 % |
| Operating temperature range (case) | -30 °C to +110 °C |
| Package size | 60.5 × 14 × 6.4 mm |
| Typical gate current | 1 mA at 5 V |
| ESD sensitivity | down to 1000 V |
The module is sensitive to ESD voltages down to 1000 V, so appropriate ESD protection measures must be taken during handling and assembly.
RoHS compliance is indicated by the letter “G” after the lot marking.
