Patent ID: 8193876

Claim:
A direct voltage and/or audio-frequency output arrangement for use in RF apparatuses of the type having at least one RF path transmitting RF signals within an RF band, the at least one RF path having a first connecting point, the direct voltage and/or audio-frequency output arrangement comprising an electrically conductive housing having a cylindrical bore defined therein, the cylindrical bore having a wall, an output path branching from the first connecting point on the RF path, the output path comprising a branch line providing a transformation and having an electrical length of L=λ/ 4 +nλ/ 2±<λ/8, wherein λ represents a wavelength within the RF band and n represents a non-negative integer n=0, 1, 2, 3 etc., and a capacitor device adjoining the branch line and providing a low-pass filter and/or an RF short, the capacitor device comprising a blocking pot further provided on the output path and arranged in the cylindrical bore defined in the housing, the blocking pot having an outer surface, the cylindrical bore wall forming a first plate of the capacitor device and the outer surface of the blocking pot forming a second plate of the capacitor device.
