Methods and systems for harmonic intermodulation testing are presently disclosed. The test system includes a signal generator configured to generate a test signal having a first frequency. The test system also includes an antenna system configured to transmit a representation of the test signal and receive a harmonic intermodulation signal. The test system also includes a filter configured to remove signals, from a representation of the harmonic intermodulation signal, over a bandwidth that includes the first frequency. The test system also includes an analysis unit configured to measure a power level of a second frequency contained in the representation of the harmonic intermodulation signal. The analysis unit is also configured to determine a passive intermodulation magnitude at any order based on the power level of second frequency.

Passive harmonic test system and method

Coaxial radio frequency ('RF') connectors for high-power handling are disclosed. Specifically, a high-power male coaxial connector ('HPMC') is disclosed. The HPMC includes a center conductor, an outer conductor disposed around the center conductor, an insulating layer positioned between the center conductor and the outer conductor, and a first elastomer. The outer conductor has an outer conductor front-end (&#x201c;OCFE&#x201d;) and the insulating layer has an insulating layer front-end (&#x201c;ILFE&#x201d;). The first elastomer is positioned between the center conductor and the insulating layer. The insulating layer may include an insulating layer cavity (&#x201c;ILC&#x201d;) extending inward into the insulating layer from the ILFE and the first elastomer may be within the ILC.
