MICROWAVE SYSTEM COMPONENTS
Below is a description of each component within
the Microwave Circuit and how these components
act within the Circuit.
Magnetron (P/N 100861)
Magnetrons supply the RF energy at 2.45 GHz
and begin to oscillate when they ar
e supplied with
approximately 4.1KVDC at approximately .350 mA.
During operation each Magnetron will output a
nominal 1 kW of power.
High Voltage Transformers (P/N 102101)
High Voltage Transformers are a ferro-resonant
design which limits fault currents and minimizes
magnetron power changes due to input voltage
changes.
The H
igh
V
oltage
Transformer supplies
the high voltage for the Voltage Doubler Circuits.
They ar
e contr
olled via the K2 Relay.
:
Never attempt to measure
the voltage values of the High Voltage
Transformers with the High Voltage Transformers
enabled. Lethal voltage will be present on your
meters. Reference page 26.
Filament Transformers (P/N 102102)
