Base Transmitter (Magnetron) 2-3 ENTERPRISE ELECTRONICS CORPORATION
The base transmitter 1A1, is the foundation for the radar system and foundation con-
sists of the necessary power distribution, cooling, system control, and various other mod-
ules that provide the transmitter with the necessary items for proper operation. The base
transmitter is not frequency or power determinate, rather the base transmitter provides the
infrastructure to other modules. For more detail, reference schematic book Volume 3.
Numerous options exist within the base transmitter; refer to the family tree for your con-
figuration.
The Base Transmitter serves as host for the specific modulator and waveguide mod-
ules detailed in Chapter 2 to operate within various radar bands:
S-Band 2700 – 3000MHz.
C-Band 5200 – 5900MHz.
X-Band 8500 – 9600MHz.
The Base Transmitter consists of the following major functional areas:
AC & DC Power.
Power Distribution Unit (1A1A2)
System Power Supply (1A1PS1)
