摘要： An electronic component includes a multilayer body including dielectric layers, a circuit pattern, and band-shaped conductor patterns. The circuit pattern includes a conductor pattern that is disposed inside the multilayer body and defines an inductor. The band-shaped conductor patterns are grounded and cover a portion of a shield surface. An internal surface is located between the circuit pattern and an upper surface. On a shield surface, a non-shielded area is provided which is not covered with any of the band-shaped conductor patterns, and through which magnetic flux generated from the inductor is able to pass.

摘要： A tunable and trimmable analog filter may include a tunable analog filter and a trimming circuit. The tunable analog filter may set the frequency of a characteristic of the tunable analog filter based on a digital tuning signal that is indicative of a desired frequency of the characteristic. However, the tunable analog filter may contain components having values that deviate from specified values due to var during manufacture of the tunable analog filter. The value deviations can cause the frequency of the characteristic not to precisely match the frequency indicated by the digital tuning signal. The trimming circuit may include a non-volatile memory that contains data. The trimming circuit may receive tuning information indicative of a desired frequency for the characteristic of the tunable analog filter. The trimming circuit may generate the digital tuning signal by trimming the tuning information to compensate for the deviations in component value and by using the data contained within the non-volatile digital memory.

摘要： A noise filter eliminates noise generated by a noise generating source in an outdoor unit in an air conditioner. Power is supplied from a power source to an indoor unit via the outdoor unit. A choke coil is formed by winding power source lines and indoor/outdoor lines inter unit lines around a common magnetic body. The number of turns of the power source lines and that of the indoor/outdoor lines are preferably set so as to be almost proportional to their impedances. Due to this arrangement, noises of the lines can be cancelled while maintaining balance of influences on the magnetic field of the choke coil.

摘要： An equalizer circuit for equalizing RF frequencies implemented as an MMIC or MIC having a series of microstrip transmission lines between an RF input terminal and an RF output terminal and having at least one shunt path comprised of a series combination of a FET able to be switched between a conducting state and a nonconducting state and a stud tuner microstrip transmission line, wherein the FET is used as a voltage variable resistor to selectively de-Q the stub tuner and thereby control the depth of the equalization curve. In a modified embodiment, artificial transmission lines which include a plurality of inductive elements and FETs are coupled to each shunt path, wherein the shunt paths may be selectively shorted by changing the state of the FETs, thereby permitting the center frequency of the equalizer circuit to be shifted as well.

摘要： To compensate for nonlinear distortions in analog optical communication transmission systems, caused by laser chirps and the chromatic dispersion of the optical fiber, an equalizer in the form of an LC component is known, whose capacitance is formed by a variable capacitance diode. If this equalizer is to be adjusted for considerable signal distortions (long transmission path length), it must operate at great capacitance, which reduces its bandwidth. In order to be able to equalize large bandwidth signals (e.g. 600 MHz) containing considerable distortions, the invention indicates an LC chain circuit with LC components of the known type, as the equalizer. Further developments of this solution concern the appropriate polarizing of the variable capacitance diode and maintaining the frequency response constant, when adjusting the equalization.
