This datasheet introduces the features and characteristics of the STEVAL-TDR011V1 demonstration board, which is a two-stage 50 W RF power amplifier that 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.
