Outline of Final Research Achievements

We have successfully developed a radio frequency (RF) filter and low-noise heterodyne mixer-preamplifier modules for a multiband receiver at 400 GHz band. The RF filter adopted a hybrid-coupled type of the multiplexer to divide the frequency range of 405-480 GHz into 3 bands. The measurement result showed excellent agreement with the simulation. The heterodyne module integrates a superconductor-insulator-superconductor (SIS) mixer with a cryogenic low-noise pre-amplifier. The measurement demonstrates 3 times wider bandwidth than the one in current existing receivers maintaining low-noise temperature. By combining the multiplexer and the modules, we demonstrated noise temperature of 200 K for a 3-band receiver. The result indicates that this approach is promising for future low-noise and wideband receiver applications.
