STEVAL-TDR033V1:60 W/896-941 MHz evaluation board based on 2x PD85050S

The STEVAL-TDR033V1 demonstration board is designed for mobile radio applications. It uses two PD85050S LDMOS transistors.

The demonstration board is a push-pull class AB power amplifier which uses a lumped L-C input/output network type on balanced microstrip lines.

A proper planar balun embedded on the PCB (patent pending) allows the management of balanced versus unbalanced input/output signals.

For additional information regarding the PD85050S please refer to the device datasheet.
