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 field- effect transistors.
The STEVAL-TDROOS5V1 is a reference design for an RF broadband power amplifier intended for linear or nonlinear operation over the band from 1.8 to 54 MHz. It utilizes two SD2943 gold metallized N-channel MOS field-effect transistors and features a temperature compensating biasing circuit that supports both Class B and Class AB operation.
| Frequency range | 1.8 - 54 MHz |
|---|---|
| Output power (typical) | 450 W |
| Supply voltage | 48 V |
| Efficiency range | 55 % - 76 % |
| Input power (max) | 10 W |
The temperature compensating biasing circuit supports Class B and Class AB operation.
The STEVAL-TDROOS5V1 has a control port named 'BIAS' to select between Class B (~100 mA) and Class AB (~900 mA).
