摘要: 722,663. Valve generating circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Jan. 19, 1963 [Jan. 19, 1952], No. 1565/53. Addition to 714,827, [Group XL (b)], Class 40 (6). [Also in Group XL (b)] A valve generating circuit comprises a valve V coupled at input to a capacitatively loaded wave-guide 4 and at output to a similar guide 8 as described in the parent Specification, and an unloaded guide 16 is coupled with one of the first two guides to remove at least one harmonic of the generated frequency. The guide 16 may contain lossy material, such as graphite 6, for absorbing the unwanted harmonic. The input and output guides have tuning screws 12 and a tuning slider 11, and a take-off coaxial line 17 is provided.
