摘要： A transmission device for suppressing the glass-fiber effect includes a circuit board and a transmission line. The circuit board includes a plurality of glass fibers, so as to define a fiber pitch. The transmission line is disposed on the circuit board. The transmission line includes a plurality of non-parallel segments. Each of the non-parallel segments of the transmission line has an offset distance with respect to a reference line. The offset distance is longer than or equal to a half of the fiber pitch.

摘要： A magnetically tunable ferrimagnetic filter, including a top casing, a top magnetic conductor, a bottom magnetic conductor, coils, a balance coil, ferrimagnetic-based filters, and a bottom casing. The ferrimagnetic-based filters utilize ferrimagnetic resonator elements, such as yttrium-iron-garnet (YIG), configured to reduce a magnetic gap of the YIG filter and thereby to improve performance.

摘要： A cable television (CATV) multi-tap system includes a tap housing. The system also includes a face plate including one or more subscriber ports. The system also includes a circuit board positioned within the tap housing and coupled to the face plate. The system also includes an access cover coupled to the tap housing. The access cover is configured to be removed from the tap housing to allow access to the circuit board without removing the face plate or the circuit board from the tap housing.

摘要： A radio frequency module includes a carrier amplifier and a peak amplifier. A 90° hybrid circuit is connected to an input end of the carrier amplifier and an input end of the peak amplifier. A coupler is connected to an output end of the carrier amplifier and an output end of the peak amplifier. A control circuit varies a threshold value of a bias voltage of the peak amplifier based on a radio frequency signal input to the 90° hybrid circuit or the carrier amplifier, and a signal indicating a drive level of the carrier amplifier, in which the carrier amplifier and the peak amplifier are included in an integrated circuit. The control circuit is included in an integrated circuit, and the integrated circuit is disposed adjacent to the integrated circuit on a peak amplifier side.

摘要： Degrees of a change in an insertion loss of a main line and a change in a phase of a signal are small regardless of whether or not detection is performed by using a sub-line. A directional coupler includes a main line, a sub-line, a first termination circuit, a second termination circuit, and a switch. The sub-line has a first end and a second end. The first termination circuit terminates the first end and the second end of the sub-line. The switch switches connection and disconnection between the sub-line and the first termination circuit.

摘要： A resonating structure and a dielectric filter having the same are disclosed. The resonating structure comprises a body, at least one set of negative coupling holes, and a conductive material layer. The body is made of a solid dielectric material and comprises at least two resonators. The negative coupling holes are formed at a connection between two adjacent resonators. Each set of negative coupling holes comprises a first blind hole and a second blind hole disposed on two opposite surfaces of the body respectively. The first blind hole and the second blind hole are offset from each other in a plane perpendicular to a direction along which the first or second blind hole is dug. The conductive material layer covers surfaces of the body and surfaces of the first blind hole and the second blind hole.

The first splitter/combiner circuit has first, second, and third input/output (I/O) ports, a first quarter wave line with a first end coupled to the first I/O port and a second end coupled to the second I/O port, a second quarter wave line with a first end coupled to the first I/O port and a second end coupled to the third I/O port, and a first resistor with first and second terminals coupled to the second and third I/O ports, respectively. The second splitter/combiner circuit has fourth, fifth, and sixth I/O ports, and a ring of multiple quarter wave lines, which includes third and fourth quarter wave lines. The third and fourth quarter wave lines each extend from the fourth I/O port in different directions from each other to the fifth and sixth I/O ports, respectively.
