2.1.4.3.5. Crossguide Coupler (Unit 2 A1 A3 A3 DC1)
Identical to the Horizontal Unit - see Paragraph 2.1.4.2.5.
2.1.4.3.6. 3-Port Circulator (Unit 2 A1 A3 A3 HY1)
Identical to the Horizontal Unit - see Paragraph 2.1.4.2.6.
2.1.4.3.7. TR Limiter (Unit 2 A1 A3 A3 V1)
Identical to the Horizontal Unit - see Paragraph 2.1.4.2.7.
2.1.4.4. Fluid Pump Assembly (Unit 2 A1 A3 A4)
The Transceiver Systems operate at a very high temperature. Simple “air cooling” techniques
found in other radar systems are not sufficient for extracting heat away from the Transmitter. To
enhance and improve the cooling capability, EEC employs a Liquid Cooling Assembly to remove
excess heat from the Transceiver units. The Liquid Cooling Assembly consists of a Weatherized
Liquid Cooler utilizing a Peltier device and a Fluid Pump Assembly. The liquid is standard
automotive antifreeze (Ethylene Glycol, Propylene Glycol or Glycerol) that can be purchased
worldwide at any automotive parts supplier.
The Fluid Pump Assembly moves the liquid through the cooling system. The Weatherized Liquid
Cooler unit (See paragraph Error! Reference source not found.) acts as the heat exchanger.

2.1.4.5. Weatherized Liquid Cooler (Unit 2 A1 A4 A6)
The Liquid Cooler is the heat exchanger unit of the Liquid Cooling System. This unit performs
the same duties as a radiator in an automobile.
