The VarioMatch match network converts 100 VAC to 240 VAC,
single-phase, to the DC voltages used in the match. The 45 W SMPS
(switched mode power supply) supplies ±15 VDC and +5 VDC. The
cooling fan is powered from the +15 V supply.
The RF power enters the VarioMatch match network via the RF-
GENERA TOR connector mounted directly on the Phase/Magnitude
detector module. The Phase/Magnitude module provides the phase
and magnitude signals to the Motor Control section. The magnitude
signal controls the load capacitor, while the phase signal controls the
tune capacitor.
