    摘要: An isolating circuit, which isolates a first frequency signal in a first frequency range and a second frequency signal in a second frequency range which is higher than the first frequency range, has as antenna terminal, a first filter and a second filter. The first filter, having a first input terminal and a first output terminal, receives a first input signal including the first frequency signal at the first input terminal and attenuates first frequency component of the first input signal below the first frequency range at a first attenuation rate and second frequency components of the first input signal above the first frequency range at a second attenuation rate. One of the first input and output terminals of the first filter is coupled to the antenna terminal. The first filter further has a first setting terminal setting the first attenuation rate and the second attenuation rate so that the second attenuation rate is greater than the first attenuation rate. The second filter, having second input and output terminals, receives a second input signal including the second frequency signal at the second input terminal and attenuataes third frequency components of the second input signal below the second frequency range at a third attenuation rate and fourth frequency components of the second input signal above the second frequency range at a fourth attenuation rate. One of the second input and output terminals of the second filter is coupled to the antenna terminal. The second filter further has a second setting terminal setting the third attenuation rate and fourth attenuation rate so that the third attenuation rate is greater than the fourth attenuation rate.

    摘要: A dielectric filter includes a unitary dielectric block formed of a uniform, single dielectric material and having electrically conductive metallized patterns formed on front, rear and lateral walls, and on an outer bottom surface thereof. A plurality of coaxial dielectric resonators each including an open end and a central conductor are longitudinally arranged along the center of a top surface of the block and are spaced apart a predetermined distance. Frequency adjusting patterns are formed on the top surface of the block, each frequency adjusting pattern extending around an open end of a respective one of the resonators. Coupling amount adjusting patterns are also disposed on the top surface of the block, each connected to the front and rear walls and disposed between adjacent ones of the frequency adjusting patterns. At least one additional coupling amount adjusting pattern is disposed on the top surface of the block. The additional coupling amount adjusting pattern has a first end mechanically connected to the front wall and a second end capacitively coupled to the rear wall, a gap being provided between the second end and the rear wall. The additional coupling amount adjusting pattern determines a pre-adjusted maximum coupling amount larger than a coupling amount of the plurality of coupling amount adjusting patterns which are connected to the front and rear walls.

    摘要: A dielectric filter includes a homogeneous monolithic block of dielectric material having a plurality of parallel extending dielectric resonators formed therein. A plurality of first electrodes extend alond the top surface of the monolithic block, each encompassing an opening in the monolithic block defined by a corresponding one of the plurality of dielectric resonators. Either the distance between adjacent dielectric resonators or the configuration of the first electrodes is established to cause an overcoupling based on the coupling impedance, thereby tuning an attenuation pole of the dielectric filter to a finite frequency. Additionally, second electrodes are provided along the top surface of the monolithic block extending between and spaced from the first electrodes and connected to a ground electrode.

    摘要: In a mobile communication device, a power amplifier amplifies the power of a signal to be transmitted. A transmitter filter limits the frequency band of the amplified signal to a predetermined frequency band for transmission. The signal limited in frequency band is transmitted via an antenna. Output power control circuitry controls the output power of the signal to be transmitted and has an output power sensor and an automatic power control circuit. The output power sensor succeeds the transmitter filter in the direction of flow of the signal to be transmitted, and senses the output power of the signal. The automatic power control circuit controls the gain of the power amplifier such that the output power sensed by the output power sensor coincides with a preselected reference value.

    摘要: An LC-type dielectric filter includes a plurality of substrate layers which are arranged in a stack and laminated to form a multi-layer substrate. Strip line resonators are provided on some of the substrate layers. The filter has a plurality of terminals, which are connected to resonators. The terminals are also capacitively or inductively coupled to each other. At least one grounding layer is included in the stack for electrically isolating the resonators. Coupling between the resonators can be obtained by forming a plurality of resonators close to one another on the same substrate layer. Further, a duplexer can be made from filters of this type. The duplexer may include a matching circuit and a power amplifier for RF transmission.
