This document shows the RF performance characteristics of the RD01MUS2 single-stage amplifier at the 450-527 MHz band, including the relationship between output power and input power.
This application note (AN‑UHF‑087‑A) presents the RF wide‑band characteristics of the Mitsubishi Electric RDO1MUS2 single‑stage power amplifier. It includes measured data for output power versus frequency, output power versus input power, and the equivalent circuit of the device.
The document provides sample history, evaluation conditions (Vds = 7.2 V, Idq = 50 mA, Pin = 30 mW), frequency‑characteristic curves, Pout‑vs‑Pin curves at several frequencies, a schematic of the equivalent circuit, and a parts list with component values and manufacturers.
| Supply voltage (Vds) | 7.2 V |
|---|---|
| Quiescent drain current (Idq) | 50 mA |
| Frequency range | 450‑527 MHz |
| Input power for Pout‑vs‑Pin curves | 30 mW |
| Maximum measured output power | 0.8 W |
The amplifier was evaluated from 450 MHz to 527 MHz.
A drain‑source voltage of 7.2 V and a quiescent drain current of 50 mA were used.
An input power of 30 mW was applied.
