The STEVAL-TDR030V1 demonstration board is designed for 2-way radio BTS and general wireless services at 28 V to 32 V. It uses two LET9060S 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 management of balanced versus unbalanced input/output signals.
For additional information regarding the LET9060S please refer to the device datasheet, available at www.st.com.
