3-3-1 TRANSMITTER BLOCK DIAGRAM DESCRIPTION
Figure 3-3-1 is a block diagram of the transmitter and Figure 3-3-2 is the RF subsystem components.
Both should be referred to during this discussion. The transmitter is located in the transmitter cabinet,
Unit 2, and contains the components that generate RF energy. The word “transmitter” is used to
encompass all the modulator circuitry including the magnetron, and the RF components. Specifically,
the transmitter includes the modulator power supply, solid-state modulator, filament transformer,
magnetron filament filter, constant voltage transformer, magnetron, magnetron and modulator metering
circuits, control circuits, trigger distribution module, control panel, and waveguide components.

Whether in track mode, beacon mode, or weather mode operation, triggering of the transmitter occurs
with the introduction of modulator triggers to the transmitter from within the Tracking Console, Unit 1.
Trigger timing and the selected pulsewidth jointly determine the operating mode of the radar system.

With all the interlock switches closed and the magnetron filament warm-up time expired, relay K5 in the
transmitter will energize applying an enabling ground to the high voltage enable terminal of the
modulator power supply.
