TRAK supplies waveguide couplers, combiners and splitters for a variety of space, defence and air defence radar applications. These devices are designed to complement TRAK waveguide isolators and terminations.
TRAK offers a broad capability in the design and supply of waveguide hybrid and loop couplers. TRAK has an expanding portfolio of couplers designed for a variety of radar and space based applications.

TRAK has supplied a large quantity of couplers over a relatively short period of time in WR34 and WR28. All of the space qualified couplers delicited to date are hybrid couplers and have been provided with or without a termination on one port or as part of more complicated passive assemblies.
Over the coming few months TRAK will expand its portfolio of space qualified hybrid couplers with the delivery in Spring 2016 of WR62 and WR75 broadband 2×1 and 2×2 designs. Follow this WR75 link to the most recent posts on the subject.
