RF termination (also called RF load or dummy load) ST4021 from Fairview Microwave

operates from DC to 40 GHz and handles up to 5 Watts (CW). This 2.92mm

termination (or load) has a male gender. ST4021 2.92mm load termination offers

1.45:1 max VSWR. This 5W 2.92mm terminator from Fairview Microwave has a

heatsink body which is designed to provide adequate heat dissipation within its

full frequency of operation.

RF terminations / loads are critical passive components in many RF, microwave

and millimeter wave systems where signal reflection from unused ports can reduce

the signal integrity can potentially damage the device. By terminating an unused

port with a matched load (dummy load), the incident energy will be absorbed with

minimal reflection. These radio frequency termination components are commonly

used to terminate devices such as couplers, circulators, and switches. Loads /

terminations are also widely used in measurement systems to ensure accurate

results. Fairview offers a large selection of in-stock RF, microwave and millimeter

wave terminations up to 65 GHz with great performance over the entire operating

range and with power handling capabilities up to 800 Watts (CW).
