Product Description

QuinStar Technology's QWC series circular-to-rectangular waveguide transitions cover the frequency range of 18 to 220 GHz in ten waveguide bands. The waveguide transitions are used to connect standard rectangular waveguide to circular waveguide with a minimum of loss and reflections.

They are available with a variety of flange types to join two components of the same waveguide size which differ in both waveguide aperture size and flange types. The transitions have a wide bandwidth and low VSWR.

Ordering Information

Model Number: QWC - ABC D E F  (Click here for automatic web quote request form)

ABC = Circular waveguide diameter in mils (thousandths of inch). (See appendix K)
D = Circular waveguide flange type:
R = Round
S = Square (K, Ka, Q, U bands)
E = Rectangular waveguide flange type:
R = Round
S = Square (K, Ka, Q, U bands)
F = Waveguide band designator:
T = 18-40 GHz (K + Ka)
K = K-band
A = Ka-band
Q = Q-band
U = U-band
V = V-band
E = E-band
W = W-band
F = F-band
D = D-band
G = G-band
