QuinStar Technology's QJX series of compact general purpose 3-port crossguide directional couplers cover the frequency range of 18 to 60 GHz in four waveguide bands with midband nominal coupling values of 20 and 30 dB. These crossguide couplers are ideal devices for sampling or inserting RF energy in a waveguide transmission line without affecting the transmitting signal. Typical applications include frequency monitoring, power sampling, and built-in testing. The crossguide type of directional coupler has the advantage of lower insertion loss, smaller size, and lower cost when compared to broadwall directional couplers.
