This document is about the evaluation board of the RD01MUS2B single-stage amplifier, with a frequency range of 890-941MHz and typical features such as input power of 30mW and output power of 1.5W.
The document provides an overview of the RDO1MUS2B single‑stage RF power amplifier evaluation board, including its operating frequency range of 890‑941 MHz, typical input power of 30 mW, typical output power of 1.5 W, and quiescent current of 40 mA. It also describes the board dimensions (90 mm × 40 mm) and construction details such as FR‑4 material and 0.8 mm thickness.
Additional sections detail the equivalent circuitry, PCB layout, full component list, thermal design of the heat sink, and typical performance graphs (frequency vs. output power, gain, efficiency, etc.). A revision history concludes the note.
