Abstract
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.
