چکیده
High Frequency Current Mode Class-D Amplifiers With High Output Power and Efficiency By Anthony Lawrence Long A 13 watt Current Mode Class-D (CMCD) with 60% efficiency is presented. This amplifier is the highest power switch mode microwave power amplifier reported to date. The CMCD architecture is an improvement over the Voltage Mode Class-D in that the parasitic reactance in the active device can be absorbed into the tank circuit resulting in a zero voltage switching condition. Additionally, two similar amplifiers are presented for use with advanced linearization techniques.
