APELC also offers a wide variety of high power RF solutions, such as ultra wide band systems, mesoband systems, and high power microwave systems.

APELC is the world leader in the development of compact Marx generators (our basis technology). We offer a very wide spectrum of Marx generators, from mJ, kV handheld models, and multi-kJ, MV bench-top systems.

Our generators are unmatched in their performance and compactness.

In support of our Marx generators, we offer a wide variety of electronics and diagnostics, including: •integratedpowersupplies •highrepratetriggergenerators •integratedlowrepratetriggergenerators •customloads •integratedhighspeeddiagnosticprobes

APELC also offers complete pulsed power systems including: •33J/600kVMarxgeneratorsystemwitha repetitionrateofmorethan250Hz. •100J/600 kV Marx generator system, with anintegrated10kJ/shighvoltagecapacitor charger. This system has been demonstrated tooperatewitharepetitionrateof100Hz.
