ABSTRACT:
An RF power-generator system for the frequency range of 2 to 30 MHz and a programmable sinusoidal power output of 0 to 1000 W. The system is constructed of modules (10, 30, 50, 70 and 90) accommodated in a shallow parallelepipedal housing (1) with a capacity of 4.6 l. The housing essentially comprises two lateral lengths (4) of structural section, a sheet-metal front (6), a sheet-metal bottom (5), and a lid. A crystal-controlled power-oscillator module (10) communicates by way of an RF line (121) with an intermediate module (30). The intermediate-amplifier module communicates by way of still another RF line (122) with a terminal power-amplifier module (50). The terminal power-amplifier module communicates by way of still another RF line (123) with a high-power filter (70). The filter communicates by way of still another RF line (124) with a high-power directional coupler (90). The RF power output can be intercepted at an RF plug (2). A flat fan (120) generates a current of air to cool the power modules (30, 50, 70 and 90). Modules (10, 30, 50 and 90) with built-in electronics all have an integrated control-and-diagnostics unit that communicates by way of multiple cable (125, 126, 127 and 128) with a processor (110). Results are displayed on a display (111). Controls (112) make it possible to employ prescribed operating modes.
