バータ。 In an SHF-UHF converter comprising a preamplifier for inputting an SHF band signal, a local oscillator, and a mixer, a waveguide-stripline converter connected to the input circuit of the preamplifier is provided. A stub is provided at the tip of the stripline to be formed in order to widen the band, and a stub is placed on each microstripline of each input/output circuit of the two-stage cascade-connected FET amplifier constituting the preamplifier. An SHF-UHF converter configured to provide sufficient attenuation characteristics to the image frequency band by providing stubs that resonate with λ4 at different frequencies in the image frequency band.
