Patent number: 6802729Abstract: A signal connector assembly with a plug contact within a plug having a high resistive portion. When the plug of the assembly first makes contact with the electrical receptacles within a mating receptacle, the high resistive portion prevents a current surge. As the plug is further inserted into the receptacle, the energy passing from the plug to the receptacle is gradually increased. Eventually, the receptacle contacts within the receptacle pass the high resistive portion and make contact with the conductive portion of the plug contact, thereby permitting transmission of valid signals without the generation of spurious errors.Type: GrantFiled: August 8, 2001Date of Patent: October 12, 2004Assignee: The Whitaker CorporationInventors: Henry Otto Hermann, Jr., Marjorie Kay Myers

Patent number: 6781065Abstract: A solder-coated article is described. The article comprises (1) a dielectric core having a largest dimension ranging from 1 to 1000 microns; (2) a solderable metal layer over the core; and (3) a solder layer over the metal layer. Preferably, the dielectric core is a spherical core of ceramic or glass material that ranges from 25 to 200 microns in diameter. Copper and nickel are preferred materials for the solderable metal layer. The solder is preferably selected from a solder comprising lead and tin and a solder comprising lead and indium, more preferably a 63% Sn-37% Pb solder, a 95% Pb-5% Sn solder, or a 50% Pb-50% In solder. Also described are modified substrates and (solder bonded assemblies) that can be created using such solder-coated articles, as well as a procedure for making the same.Type: GrantFiled: June 8, 2000Date of Patent: August 24, 2004Assignee: The Whitaker CorporationInventor: William James Palmteer

Patent number: 6759742Abstract: A method for making a bond-wire interconnect to pass signals between different substrates is described. According to this process, a first compensated bond wire interconnect is made to connect two substrates of a first type at an operating frequency, the first interconnect comprising a bond-wire of a fixed length and a first pair of compensation structures formed from a lowpass filter prototype. A second compensated bond wire interconnect is made to connect two substrates of a second type at the operating frequency, the second interconnect having a bond-wire of the fixed length and a second pair of compensation structures formed from the lowpass filter prototype. A bond-wire of the fixed length, one compensation structure from the first pair, and one compensation structure from the second pair, are combined to make a third compensated bond wire interconnect to connect a substrate of the first type with a substrate of the second type at the operating frequency.Type: GrantFiled: October 12, 1999Date of Patent: July 6, 2004Assignee: The Whitaker CorporationInventor: Thomas Philip Budka

Patent number: 6647244Abstract: A wireless communications system has a plurality of base stations 1, a plurality of mobile vehicular repeater units 2, and a plurality of portable units 3. In a public safety network context, each mobile vehicular repeater unit 2 is associated with a portable unit 3, and both are associated with a single user. The object is for the user to be able to access the wireless network for any geographic location. In cases where a geographic area is shadowed from a base station 1 and communication directly between the portable unit 3 and the base station 1 is not possible, it is beneficial to use the mobile vehicular repeater unit 2 as a vehicular repeater to relay communications between the portable unit 3 and the base station 1. When the mobile vehicular repeater unit 2 is operating as a repeater and communicating with the portable units, the frequency plan for transmission and reception is reversed.Type: GrantFiled: November 16, 1999Date of Patent: November 11, 2003Assignee: The Whitaker CorporationInventors: William Dean Haymond, Daniel Wayne Ericson

Patent number: 6642559Abstract: An isolation structure for high frequency integrated circuits is a conductive material disposed over a region of active gallium arsenide substrate. The conductive material over the active region creates a lossy RF path to reduce undesired coupling between adjacent conductors. In one case, two RF signal lines (1,2) terminated at the same via pad (3) have weaker coupling than in prior art via structures due to the lossy RF structure disposed on isolating fractional portions (10,11) of the via pad (3). The isolating fractional portion (10,11) are intermediate terminating fractional portions (8,9) of the via pad (3) to which the signal lines (1,2) are connected. In another case, two parallel bias lines (12,13) are disposed over an active layer region (6) increasing the RF loss between them and advantageously reducing the RF coupling. The reduced RF coupling improves RF isolation and permits increased miniaturization.Type: GrantFiled: April 14, 1999Date of Patent: November 4, 2003Assignee: The Whitaker CorporationInventors: Kenneth Vern Buer, Anthony Francis Quaglietta, Allen Hanson

Each of the signal contacts has a signal conductor termination slot configured for insulation displacement termination of a respective said signal conductor. The ground bus has a plurality of ground conductor termination slots each configured for insulation displacement termination of a respective said ground conductor, and at least one bypass slot configured to permit at least one of said signal conductors to pass through said ground bus without termination thereto. The signal conductor termination slots, the ground conductor termination slots and the at least one bypass slot are arranged such that the plurality of signal and ground conductors reside in a common plane in the connector after termination thereto.Type: GrantFiled: December 18, 2001Date of Patent: October 28, 2003Assignee: The Whitaker CorporationInventors: Michael Warren Fogg, Mai-Loan Thi Tran, Benjamin Howard Mosser, III, Robert Correll, Jr.

Patent number: 6595796Abstract: A backer plate (40) secured to leading end portion (20) of flexible film circuit (10), providing rigidity to facilitate manipulation of the circuit during mating with and unmating from a receptacle connector (26). Backer plate (40) may either be molded of insulative material or be conductive to serve as a ground connection. Backer plate (40) has side walls (48) beside the flex film that provide flanges (54) to precisely guide mating with connector (26) along slots (32), and may also provide detents (56) for retention in the connector. Backer plate (40) may also provide bosses (60) to stop forward movement at a precise location aligning the strip circuits with connector contacts (30). Flanges (54) offset from the central plane of the strip/backer plate assembly, line up with slots (32) offset from the central plane of cavity (24) in order to permit insertion only when the assembly is properly oriented, thus serving to polarize the assembly.Type: GrantFiled: February 25, 1998Date of Patent: July 22, 2003Assignee: The Whitaker CorporationInventors: Keith Scott Koegel, Earl Chester Myers, Jr.
