Publication number: 20070159268Abstract: A coupler assembly may include first and second electromagnetic couplers connected together. In some examples, the couplers may be connected in cascade configuration, with at least the second coupler including at least third and fourth couplers connected in tandem configuration. In some examples, a first asymmetric coupler may include a plurality of coupler sections connected in cascade configuration, and a second coupler connected to the first coupler in tandem configuration. In some examples, a direct port of a first coupler section may be conductively connected through a second coupler section to an isolated port of the first coupler section.Type: ApplicationFiled: March 7, 2007Publication date: July 12, 2007Applicant: Werlatone, Inc.Inventor: Allen Podell

Publication number: 20050264374Abstract: A radio-frequency impedance device includes a resistor device mounted on a surface of a dielectric layer, and adapted to be connected between a transmission line and an output terminal associated with a load impedance. A ground conductor may extend opposite a portion of the resistor device. Further, a conductor assembly may couple a first end of the resistor device to a transmission line. The conductor assembly may include a first portion extending along the first layer face on opposite sides of the resistor device adjacent to at least the first resistor end, or a second portion extending along the fourth layer face opposite from the ground conductor. The configuration of devices may produce, in operation, an electric field distributed along the resistor device, providing corresponding distributed current density along the resistor device over a broad frequency band.Type: ApplicationFiled: June 1, 2004Publication date: December 1, 2005Inventor: Allen Podell

Publication number: 20050156686Abstract: A coupler is disclosed that includes first and second mutually coupled spirals or loops disposed on opposite sides of a dielectric substrate. The substrate may be formed of one or more layers and the loops may have a number of turns appropriate for a given application. Conductors forming the loops may be opposite each other on the substrate and each loop may include one or more portions on each side of the substrate. Each conductor of the coupler may include an intermediate portion having a width that is more than the width of end portions. An extension may extend from each respective intermediate portion, with the two extensions extending in non-overlapping relationship. In some coupler sections, an extension may be peninsular.Type: ApplicationFiled: February 7, 2005Publication date: July 21, 2005Inventor: Allen Podell

Publication number: 20050146394Abstract: Couplers are disclosed that include first and second mutually coupled conductors. The coupled conductors may be regular or irregular in configuration, and for example, may be linear, including rectilinear or with one or more curves, bends or turns, such as forming a ring, coil, spiral or other loop. One or more sections of a coupler may be on different levels and separated by a dielectric medium, such as air or a dielectric substrate. Coupled conductors may be facing each other on the same or spaced-apart dielectric surfaces, such as opposing surfaces of a common substrate, and each conductor may include one or more portions on each side or surface of a substrate. In some examples, a coupler may include plural coupled sections, with conductors in one section being only broadside coupled, and conductors in another section being edge-coupled.Type: ApplicationFiled: March 8, 2005Publication date: July 7, 2005Inventor: Allen Podell

Publication number: 20050122186Abstract: A circuit assembly may include one or more coupler sections, and may include a phase inverter and/or a phase shifter. A coupler section may include a phase inverter. A coupler may include first and second mutually coupled spirals disposed on opposite sides of a dielectric substrate. Conductors forming the spirals may be opposite each other on the substrate and each spiral may include one or more portions on each side of the substrate. Some circuit assemblies may include first and second multi-port coupler sections. A phase inverter or a phase shifter may be coupled between coupler sections. In some examples, a circuit assembly may include first and second conductors each having first and second ends and mutually inductively coupled turns, and a capacitive device coupling the first ends of the first and second conductors to a reference potential.Type: ApplicationFiled: June 4, 2004Publication date: June 9, 2005Inventor: Allen Podell

Patent number: 5657326Abstract: A collision detection method and apparatus which is suitable for use in a wireless CSMA/CD network, or other wireless networks where collision detection is provided. The apparatus includes a detector which detects intermodulation or other mixing products of colliding data transmissions at a station in the network, and a signal processor which indicates collisions between the data transmissions based upon characteristics of the intermodulation products. The system is capable of detecting collisions, both between transmissions from the station on which the device is located and transmissions from other sources, and between two transmissions being received from other sources. The station includes a transmitter having an input for a data packet. Resources coupled to the input add a header to the data packet, the header having characteristics monitored by the collision detector circuitry including a pseudo-random bit sequence.Type: GrantFiled: December 20, 1994Date of Patent: August 12, 1997Assignee: 3Com CorporationInventors: Lawrence M. Burns, Allen Podell, David A. Fisher, Ravi Ramachandran
