This document describes the output power control method for RA45H7687M1.
The document provides a recommendation for controlling the output power of the RA45H7687M1 RF power semiconductor. It describes the block diagram, required internal resistor value, and the supply voltage needed for stable operation.
Detailed tables and contour maps illustrate the relationship between input power, adjuster settings, and output power across the 764‑870 MHz frequency range, helping designers select appropriate resistor values and bias voltages.
| Internal resistor value | 15 kΩ |
|---|---|
| Supply voltage Vgc (ground reference) | 3.4 V (tolerance ±7 %) |
| Output power range | 1.5 W to 45 W |
| Operating frequency range | 764 MHz – 870 MHz |
The recommended internal resistor value is 15 kΩ.
A DC voltage of 3.4 V (±7 %) is required between Vgc and ground.
The device can deliver output power from about 1.5 W up to 45 W.
