    摘要: In the manufacture of a high-frequency assembly, a plurality of components, at least one (12) of which is frequency-­specific, are placed with respect to each other using a placing apparatus and are interconnected. In a specimen of the frequency- specific component (12, 30) a feature (23, 24) which encodes the frequency is looked for. The specimen is built in if the feature (23, 24; 26) is found in the specimen and is judged to be correct; otherwise the specimen is rejected.

    摘要: In a wavelength-selective optical signal processing device, an outcoupling filter for decomposing an incoming wavelength multiplex comprising a plurality of channels at different wavelengths into a first and a second group of channels and an incoupling filter for combining the first group after having passed through a processing unit and the second group into an outgoing wavelength multiplex are combined in a continuous wavelength-selective reflecting structure.

    摘要: A Forward Error Correction coding method comprises a generalised concatenated code comprising a plurality of outer component codes (Ai) and a plurality of inner component codes (B’i ). The outer components codes comprise Reed-Solomon (RS) codes and a plurality of binary codes of equal length but varying rates. The inner component codes have a nested structure and are defined by the sum of disjoint BoseChaudhuri-Hocquenghem (BCH) codes. The component codes Ai and B’i are selected such that the product of the minimum Hamming distances of the inner and outer component codes, Did’i , are as equal as possible. Moreover the component codes are selected by matching cyclotomic cosets of inner BCH codes and type and multiplicity of outer codes.

    摘要: In order to transmit messages on an optical fiber (6), a multitude of message carrier channels (12) with different carrier frequencies, and a number of filling channels (13) are used that are transmitted together with the message carrier channels (12) over the fiber (6). The optical total power of the message carrier channels and of the filling channels is constantly held in that every change in power of the message carrier channels is compensated for by an opposite and equal change in the optical power of the filling channels. The change in the optical power of the filling channels is divided over the individual filling channels in such a manner that a minimal shifting of the center of the common spectrum of message carrier channels and of filling channels results.

    摘要: A hollow waveguide group antenna comprises a hollow waveguide (13) extending in a direction in space and a plurality of chambers (15), each of which has a sending/receiving slit (16) and is coupled to the hollow waveguide (13) by a coupling slit (14). The sending/receiving slits (16) are distributed at a fixed distance from each other, and the distribution of the coupling slits (14) in said direction in space at the transversal hollow waveguide (13) is selected differently from the distribution of the sending/receiving slits (16) such that a wave propagating (13) at the working frequency excites the sending/receiving slits (16) with amplitudes and phases suitable for realizing a sector direction characteristic. The fixed distance is approximately 0.5 λ0 40 for a 90° sector direction characteristic and approximately 0.64 Xo for a 45° sector direction characteristic.

    摘要: In a method and an arrangement for automatic adjustment of devices having setting elements, and a corresponding computer program product and computer-readable storage medium, the adjustment comprises the following steps: (a) Carrying out a first measurement of a characteristic curve to be controlled by the adjustment at predefined measurement points, each setting element assuming a reference setting, (b) testing a termination condition and terminating the method if this condition is satisfied, executing the following steps if the terminating condition is not satisfied, (c) modifying the reference setting of a setting element and measuring the characteristic curve again at predefined measurement points for this configuration of the setting elements (d) reproducing the initial reference setting of the setting element modified in step (c), (e) when there is more than one setting element, (f) calculating the gradient functions of the characteristic curve, (g) calculating new settings of the setting elements by minimizing an error function by using the measured values obtained in steps (a) and (c) and the gradient functions calculated in step (f), and (h) carrying out the method again, beginning with step (a), the settings calculated in step (g) serving as the new reference setting.

    摘要: A feedthrough for feeding a microwave signal through a wall (10) of a casing comprises a signal waveguide (11) having at least two portions (12, 13, 14) having different cross- sections. The portion (13) having the smaller cross-section is filled with plastically-deformable dielectric material which, under the action of pressure and heat, is bonded to the walls of the portion (13) in which it is located. The dimensions of the portion (13) are such as to provide an impedance match with the adjacent portions ( 12, 14 ). An antenna (17) couples electromagnetic energy between the waveguide and a strip transmission line (19). A metal cap (20) seals the end of the waveguide and screens the antenna.

    摘要: A capacitor element on a chip, e.g. a MMIC chip, comprises a main capacitance in parallel with a series configuration of trimming capacitors. The total capacitance in parallel with a series configuration of trimming capacitors. The total capacitance value of the parallel arrangement can be increased from its inherently minimum value by applying one or more laser pulses to one or more of the trimming capacitors, such that in each case a short-circuit is produced between the metallization layer to which the pulse is applied and the other metallization layer making up the trimming capacitor.
