This application note shows the TETRA data.
The document presents RF characteristics of the Mitsubishi Electric RD01MUS2B and RD07MUS2B TETRA 2‑stage power amplifiers. It includes sample history, measurement setup, and result graphs for output power, gain, and efficiency at three carrier frequencies.
Measurement conditions are listed (frequency, supply voltage, quiescent currents, symbol rate, bandwidth, channel spacing) and the results are shown in ACP vs. Pout, Gp, and PAE plots. An equivalent circuit diagram and a test block diagram are provided in the later pages.
| Operating frequency | 380 / 405 / 430 MHz |
|---|---|
| Supply voltage (Vdd) | 7.2 V |
| Quiescent current Idq1 | 40 mA or 150 mA |
| Symbol rate | 18 ksps |
| Bandwidth | 18 kHz |
| Channel spacing | 25 kHz / 50 kHz / 75 kHz |
The amplifiers were measured at 380 MHz, 405 MHz, and 430 MHz.
The equivalent circuit diagram is shown on page 5 of the document.
