Tallguide TG31 for 33 to 55 Ghz. TG31 replaces WR22 waveguide.
Signal linearity is key in communication and radar systems.
Any distortions introduced into the communications path degrade overall signal quality. Subsequent signals processing, down conversions, remodulation or retransmission strategies do not improve or perfect signal clarity for the end user. For waveguide, signal distortions are introduced into the waveguide run by dispersion and by excitation of higher order waveguide modes. In particular, this paper will show that ultra low transmission loss Tallguide transmission lines have superior linearity over standard waveguide. As an example, standard WR22 waveguide is compared to Tallguide TG31 over the 33 to 55 GHz frequency range.
