Quick Product Info:

Short Circuits - Series 050 - Read More>> (PDF)

•      Variable, Precision
•      Non-contacting choked piston
•      Precision micrometer lockable drive.

Flann waveguide Short Circuits features a length of waveguide which houses a non-contacting choked low-high-low impedance piston.  Careful choke design ensures freedom from spurious resonances.

The piston movement for each model is greater than half the wavelength at the lowest frequency. Reflection coefficient is >0.995 up to WG19 reducing to >0.980 for WG27.

Waveguide Straights & Flange to Flange Adaptors 1.14 to 110 GHz Read More>> (PDF)

The Flann Series 441 of Waveguide Straights and Flange to Flange Adaptors are available in waveguide bands from 1.14 to 112 GHz. The overall length and flange types must be specified at the time of inquiry.

Bends - Series 460/470 - 2.6 to 110 GHz - Read More>> (PDF)

Flann Waveguide bends are available in E and H Plane configurations with an angle of 90 degrees. Bends to other angles can be supplied to special order.  Typical VSWR of 1.05:1 is seen from WG10 to WG19 rising to 1.1:1 for bends in the WG20 to WG29 range.

Twists - Series 450 - 6.58 to 110 GHz - Read More>> (PDF)

Flann Twists are manufactured from sections of standard waveguide which have been precisely twisted whilst maintaining the internal waveguide dimensions.  Standard Models are 90 degree left hand twists. Other configurations and angles are available on special order.

Tees - Series 380 - Read More>> (PDF)

The Series 380 Matched Hybrid Tees have been designed to provide very high quality performance in terms of isolation, VSWR and bandwidth in frequency bands up to 140 GHz

Tees - Series 390 - Read More>> (PDF)

The Series 390 range of un-matched Hybrid Tees are waveguide sections accurately machined and assembled to form a conventional hybrid tee junction.

Tees - Series 400/410 - Read More>> (PDF)

The Series 400 E plane and H plane matched tees are constructed from precision machined section accurately assembled to form the completed component.

Tees - Series 420/430 - Read More>> (PDF)

The Series 420/430 are manufactured from sections of standard waveguide precisely assembled to produce excellent dimensional symmetry ensuring good power division characteristics. Outputs from H plane tees are in phase whereas E plane tees are of opposite phase.
