Termination loads, also call dummy loads, are the passive 1-port interconnect devices, which provide a resistive power termination to properly terminate the output port of a device or to terminate one end of an RF cable. HDG-Telecom Termination loads are characterized by low VSWR, high power capacity and performance stability. Widely used for DMA/GMS/DCS/UMTS/WIFI/WIMAX etc.

What are the functions of RF dummy load?
● When test a radio transmitter, a dummy load acts as protector of the transmitter. The transmitter may result in being damaged if there is no such a dummy load. An antenna is the normal load for the test, while a dummy load is the replacement of the antenna. A dummy load with 50 ohms gives your transmitter the proper resistance, protecting it at its final RF amplifier stage, so it is also called 50 ohm dummy load.
● When test and adjust the transmitter, you may receive other radios signal on your test frequency, which can cause interference. The dummy load is able to avoid RF wave reflections which can cause distortion of information. As a result, you can get correct adjustments.In the same way, you won’t QRM (artificial interference to transmission) others’ transmitter adjustment.
● It is also used as a substitute of the loudspeaker during audio amplifier testing.
