450 W / 1.8-54 MHz reference design based on 2xSD2943 (STEVAL-TDR005V1)
The STEVAL-TDR005V1 is a RF broadband power amplifier intended for linear or nonlinear operation over the band 1.8 to 54 MHz using 2x SD2943 gold metallized N-channel MOS fieldeffect transistors. The temperature compensating biasing circuit supports class B and class AB operation.
STEVAL-TDR005V1 is designed in cooperation with Specific RF Devices (Germany).
