Displaying performance up to 33GHz, the new family of waveguide directional couplers from Pasternack are commonly used for signal sampling and other general purpose applications in wireless transmit/receive systems, satellite communications, radar systems, point-to-point backhaul and telecom.

Pasternack’s latest release of waveguide directional couplers consists of 74 models spanning a frequency range of 5.85-33GHz across eight frequency bands. The couplers are offered in two physical configurations including ‘Crossguide’ and ‘Broadwall’ versions and come with either UG-style or CPR-style flanges.

The couplers are offered in various waveguide sizes from WR-137 to WR-34 and are offered in 10, 20, 30, 40 and 50dB coupling levels with full waveguide operational bandwidth. These waveguide couplers also include low insertion loss and typical VSWR of 1.05:1. These couplers are constructed using rugged copper alloy.

“Pasternack’s rapidly growing portfolio of waveguide components is purposely designed to meet the increasing demands of the industry across a broad range of frequencies,” said Mark Blackwood, Passive Components Product Manager at Pasternack. “This selection of couplers adds a full complement of mid and lower frequency couplers to our already existing lines of high frequency waveguide couplers.”
