Directional couplers are used in waveguide transmission systems to monitor RF power. Mega Industries offers single, double and triple loop directional couplers. These are factory set at different coupling values for forward and reverse waves, per application demand. Our standard size range is WR159 to WR2300. Contact Mega Sales if you do not see the configuration your high-power microwave application requires.
