Device for controlling the radio-frequency power output by a microwave generator

摘要

For this purpose, a control voltage source (25) is used which supplies a variable pulse-shaped control voltage (USI) and possibly a variable control direct voltage (USG). Both control voltages influence the radio-frequency power via an electromagnet (12) belonging to the microwave generator (10). The radio-frequency power is exclusively controlled on the low-voltage side of the microwave generator. <IMAGE>
