PD85050S based RF power module for mobile radio applications

STEVAL-TDR034V1

Overview

The STEVAL-TDR034V1 demonstration board is a 70 W hybrid RF power module for 12.5 V mobile radios that operate in the 380-470 MHz band.

This module is a 3-stage lineup power amplifier using the PD84002, the PD85006L-E and two PD85050S specially designed for broadband operation, which allows power control, high gain and high efficiency.
The board uses devices in plastic packages to ensure a high moisture sensitivity level.
