An RG-50/U waveguide is rectangular with an interior cross section of 34.9 by 15.8 mm.
(a) What is the name of the dominant mode in this waveguide
(b) Over what frequency range is the dominant mode the only mode of propagation
(c) What length of this guide is required to achieve a phase shift of 180° at 6 GHz
(d) Draw a dimensioned cross-sectional sketch showing how a probe can be used to couple power to this waveguide.
(e) A signal with a bandwidth of 80 MHZ and a center frequency at 6 GHz is transmitted down 100 m of this waveguide. Calculate the dispersion, that is, the difference in the length of time it takes for the highest and lowest frequencies to propagate down the guide.
