2-stage RF power amplifier with LPF based on the
PD85006L-E and STAP85050 RF power transistors
Introduction
This user manual briefly describes the function and use of the STEVAL-TDR011V1
demonstration board.
The board is a two-stage 50 W RF power amplifier which includes an output LPF (low-pass
filter) for harmonics rejection. It also features power detection and a temperature sensor.
The main purpose of the board is to demonstrate the functioning and performance of the
PD85006L-E and the STAP85050 devices from the LdmoST plastic family of RF power
transistors.
The application is specifically designed for 2-way analog and digital mobile radios.
