摘要： Variable attenuators (200, 400, 618, 620) and methods of their operation are provided. A variable attenuator (200, 400, 618, 620) includes first and second variable resistance circuits (210, 411, 250, 451) and multiple additional resistors (222, 223, 230, 231, 423, 424, 432, 433). The first variable resistance circuit (210, 411) has a plurality of current paths (212, 213, 214, 414, 415) coupled in parallel between input and output terminals (202, 405, 204, 406). A first current path (213, 415) includes two first resistors (222, 223, 423, 424) coupled in series between the input and output terminals, and a switch (230, 432), which has a channel coupled across one of the two first resistors. The multiple additional resistors include second and third resistors (230, 432, 231, 433). The second resistor (230, 432) is coupled between the input terminal and an intermediate node (206, 408). The third resistor (231, 433) is coupled between the output terminal and the intermediate node (206, 408). The second variable resistance circuit (250, 451) is coupled between the intermediate node and a voltage reference terminal (270, 470). The level of attenuation provided by the attenuator is controlled by a switch control circuit (300, 500) based on a digital input.

摘要： A PIN diode network includes a PIN diode (250) in parallel with an inductor (Ll 220; L2 230). In an off-state of the PIN diode (250) the inductor (Ll 220; L2 230) forms a resonant tank circuit with the PIN diode (250) based on the stray capacitance of the PIN diode. Thus at the operating frequency, isolation for the PIN diode is improved over the PlN diode alone.

摘要： A variable impedance circuit for use in an external circuit whereby the impedance may be altered by the external circuit has a plurality of two terminal impedance elements (12) connected in series. A node (42, 43, 55) is provided between each pair of impedance elements in the series chain (40). The first impedance element (13) and the last impedance element (15) in the series chain (40) are connected to terminals (14, 16), at least one of which is accessible for connection to the external circuit. Each of the nodes (42, 43, 55) may be connected to a terminal (18) which is also accessible for connection to the external circuit. An electrically reprogrammed read-only memory (25) stores the identity of the nde connected such that the identity of this node is retained when power is removed from the variable impedance circuit. When power is returned to the circuit, the node which was previously connected to the terminal is automatically reconnected.

摘要： A monolithic signal scrambler comprising a transmission line section (52) formed on a ceramic substrate (62), including resonant line sections (64) disposed adjacent to the transmission line path on the substrate and selectively energized to cause a predetermined signal loss through the conductive transmission line path according to the resonant frequency of the activated resonant line sections. The scrambler according to one embodiment of the present invention includes 12 resonant line sections, each tuned to approximately coincide at the preferred frequency, whereupon the loss caused by the activated resonant sections adds a significant signal loss through the transmission line path at a particular selected frequency. As a result, when used as part of a TV cable distribution system, selective activation of the scrambler provides effectively complete suppression of a selected premium signal channel while maintaining accurate control of the signal attenuation characteristics in the process. Two embodiments are disclosed, wherein the first is an active circuit, and the second is a passive, hermetically packaged filter to be installed in the line of a TV cable distribution system between the standard four-port tap and the subscriber's TV set.

摘要： An attenuator for attenuating a signal is disclosed. The attenuator comprises a differential input port with a positive input node and a negative input node to receive the signal; and a differential output port with a positive output node and a negative output node to output the attenuated signal. The attenuator further comprises a first switched resistor network connected between the positive input node and the positive output node; and a second switched resistor network connected between the negative input node and the negative output node. Further a pair of compensation paths is connected to the first and second switched resistor networks for cancellation their parasitic leakages, where a first compensation path is connected between the positive input node and the negative output node, and a second compensation path is connected between the negative input node and the positive output node. The attenuator further comprises a control circuit to generate control signals for controlling the first and second switched resistor networks.

摘要： Embodiments of methods and systems for attenuator phase compensation are described. In an embodiment, a method for attenuator phase compensation involves determining a phase compensation value for an attenuator based on an attenuation configuration of the attenuator and performing phase compensation according to the phase compensation value to maintain a constant phase response. The method may comprise determining the phase compensation value for the attenuator from a predetermined look-up table, LUT, of different phase compensation values and adjustable impedance configurations of the attenuator based on the adjustable impedance value of the attenuator.
