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. |
