Series-fed coplanar waveguide embedding circuits are being developed for terahertz mixers using, in particular, submicron-sized superconducting devices, such as hot electron bolometers as the nonlinear element. Although these mixers show promising performance, they usually also show a considerable downward shift in the resonating frequency, when compared with simulations using simplified models. This makes it very difficult to design low-noise mixers for a given THz frequency. This shift is… CONTINUE READING
