 note = {A balanced converter used in radiometer at microwave frequencies should have an exellent balance over the required frequency band. Two types of converter elements，which can be used in such a balanced converter，are described in this paper. Each has good frequency characteristic less than 1.05 in VSWR over the frequency band 3750 ± 60 Mc/s. Crystal is matched to the line in one case through a tapered ridge waveguide， which is easy to adjust but comparatively long in dimension，and in the other through a λg/4 transformer， which is comparatively short but hard to adjust.},
