%X This paper presents a new two-way Gysel combiner based on an air dielectric stripline which allows to handle very high RF power levels with low-loss suitable for power combination in accelerator applications. 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.
