A method for Passive Intermodulation measurements based on phase adjustable multicarrier
With the development of multi-beam satellites communication and the wide application of transmit-receive technology, Passive Intermodulation(PIM) has become more seriously in the high power passive components. A PIM measurement method for phase adjustable Multiple-Input Multiple-Output(MIMO) multicarrier is presented based on that for dual carriers test according to the working mode of multi-beam satellites communication. Theories as well as experiments demonstrate the potentials and usefulness of the method. The experiments are conducted by the designed 7-channel test system under -60~60 ℃, and the PIM power level is below -155 dBm. The proposed test system has been applied to the multi-carrier components of satellites.
