Summation of signals during energy extraction from 3-cm range oversized cavities

Data on the summation of signals from two synchronously operating resonant microwave (3-cm) compressors with oversized cavities are described. The ene rgy was extracted with interference switches. The summation was performed i n a waveguide tee and a 3-dB three-slot bridge. For a signal duration of si milar to 30 ns at a level of 0.5, a peak power of similar to 1 MW, and an e fficiency of similar to 30%, a gain was found to approach similar to 11 dB.
