The insertion loss of the combiner is 0.1 dB (2\%). A thick stripline implementation allows improving the power capability in both CW and pulsed operation. In addition, a mechanical tuner allows compensating for assembly and fabrication discrepancies. A methodology of design the Gysel combiner is presented as well as high power measurements up to 22 kW in pulsed mode. Simulations and measurements are in very good agreement.} }
