The Keysight U752D is an essential part of many microwave measurement applications. Attenuation measurements, reflectometer setups, power measurements, source leveling and network analysis are just a few areas in which directional couplers find use.The Keysight U752D coupler is designed with split-block technology, and provides greater than 39 dB directivity. Split-block designs are used to assure greater precision in machining the ultra-small internal dimensions required by the 40 to 60 GHz waveguide. The split-block units are equipped to interface with the precision circular cover flanges with matching alignment pins common to those applications.Each coupler is swept-frequency tested to ensure that the main guide SWR and directivity specifications are accurate. Performance characteristics are unaffected by humidity, temperature and time. This makes these units especially useful in microwave “standards” measurements.
