Terahertz Quasi-Optical Frequency Phase Shifter with Crystal Quartz Phase Sections
SINOPSIS
A frequency phase shifter (FPS) for quasi-optical transmission line with phase sections made of crystal quartz and polarizers executed on the basis of small-period wire gratings is considered. The FPS is intended for operation in terahertz (THz) frequency band at the frequency of f0 = 0.89 THz. The influence of the differential phase shift deviation in the sections on the output signal spectrum as well as the influence of the sections mismatch upon the reflected signal spectrum are considered. In the frequency bandwidth of ± 5% f0 the levels of the spurious spectral components of the FPS output signal are less than −40 dB and the levels of the shifted and reflected spectral components of the reflection signal are less than −70 dB with respect to the level of the payload signal component of the shifted frequency.
