Introduction
2
The Model 8203 Termaline Load Resistor will take a load of up to 600 W, over a
frequency range of DC to 1000 MHz. Its maximum VSWR rating is 1.1 to 1.0 over
this frequency range.
Note:
The specifications for the Model 8203 apply only as long as
the ambient temperature remains at 30°C (+86°F) or lower.
Dimensions and Weight
The Models 8201 and 8203 are 16-13/16 inches L x 5-15/16 inches W x 8-1/2
inches H (427 x 151 x 216 mm). They have a net weight of 20.4 lb (9.2 kg) and a
shipping weight of approximately 26 lb (12 kg).
Power and Utility Requirements
As load resistors, the Models 8201 and 8203 are passive devices that are self
contained and do not require a source of power or utility service to perform
their function, other than the RF input power.
Environmental Requirements
The load should be operated in an environment as free of dust and vibration as
possible. For proper operation the ambient temperature should remain within
the range of -40°C to +45°C (-40°F to +113°F) for Model 8201 and -40°C to +30°C
(-40°F to +86°F) for Model 8203. Allow at least six inches of clear space around
the load to provide an unimpeded flow of convection air currents for adequate
heat dissipation.
Items Supplied
The load is equipped with:
Model 8201 — Female N connector of a patented “Quick-Change”
design.
Instruction Manual.
Model 8203 — Double Male N adapter, and a connector dust cap.
Instruction Manual.
Because these load resistors are self contained, they have no additional parts.
