Flann has developed a new range of double ridge multihole coupler for standard double ridge waveguide sizes and tailored to any special bandwidth requirements.Full field analysis has been combined with modern theory to provide fast accurate optimisation. Our unique design of the coupler array combined with precision machining practice provides better than 40dB directivity full band with typical directivities better than 45dB achieved.Flann is now able to provide a service to make any standard or non standard type of coupler within the constraints of commercially viability
We are now able to offer the industry’s only 40dB directivity coupler with a full band coupling flatness of less than +/-1dB.
All double ridge couplers are available in coupling values of 10 – 50dB.

Double Ridge Switches

Features
• Competitively Priced
• Low VSWR
• High Repeatability
• High Isolation, 70dB
• Manual Versions Available
• Up to 40GHz                                             Read More>>(PDF)

Flann have now further extended their product range by offering D.C. Operated Double Ridge Waveguide Switches based on our successful range of series 334-2E switches
We also offer manual operated double ridge waveguide switchs on request. Please consult our sales office for more details. This new series of 2 channel, 4 port D.C. Operated waveguide switch incorporates previous well proven designs offering high isolation between ports at competitive prices.
The drive circuitry is an integral part of each switch and derives all its power from the input drive pulse which is generated by the user according to the electrical drive specifications.

Double Ridge Terminations

Features
• Low VSWR over full band range
• Low, Medium and High Power versions of the terminations are available
• Models up to 40GHz
• Low, Medium and High Power                      Read More>>(PDF)

By using state of the art design tools coupled with CAD/CAM manufacturing technologies we can now offer, the new series of WRD Low, Medium and High Power Terminations which have been successfully developed to be used within the Sat Comms industry, giving us a new product to offer customer.
All terminations have been designed to give high durability and reliability.
Note all units specified below are cooled by natural convection, power levels can be increased by use of forced air.  Optimised VSWR terminations and those operating at higher power levels can be manufactured on request.
