Miniature Air Dielectric Directional Couplers RLC Electronics' miniature air dielectric directional couplers are rugged lightweight devices that offer lower insertion loss than comparable stripline units. The simplified construction allows for greater flexibility in creating customized configurations. Any port can be used as the input with these symmetrical devices. The standard units are available with a choice of coupling values and frequency ranges and an optional termination. Specifications ADC-1-2-3 Model.
