Publication number: 20140342581Abstract: A vertical mount PCB coax connector having a unique cavity design. The examples provide a vertical mounted connector with improved electrical performance to transmit a microwave signal to or from a coaxial port to planar printed circuitry. The vertical mount PCB connector includes a threaded housing with a four post flange for attachment to the PCB, a center conductor and a dielectric bead to support the center conductor. The bottom of the flange has a uniquely contoured cavity to provide air space for the electromagnetic field above the planar transmission line. Four posts at the corners of the flange serve as the ground connection from the connector to the substrate ground planes. The open or large cavity under the flange is designed to provide high values of inductive reactance at the high end of the microwave band and typically requires changing the planar geometry to achieve even a narrow band impedance match.Type: ApplicationFiled: March 13, 2014Publication date: November 20, 2014Applicant: Southwest Microwave, Inc.Inventors: Clarence L. Clyatt, Robert Griffin, Peter Frank

Patent number: 8606114Abstract: The present invention provides a method and apparatus for phase aligning two optical signals within an optical transmitter to each other (and, in some embodiments, to a pulse carved optical signal) using integrated complimentary taps and a dither signal. The phase of a first signal may be intentionally offset relative to the phase of a second signal. Based on the offset, a correction factor may be calculated. The correction factor may be used to shift the phase of the first signal and/or the second signal in order to generally align the signals. This procedure may be automatically performed in a feedback loop to cause the signals to come into alignment and maintain the alignment of the signals during operation of the transmitter.Type: GrantFiled: May 17, 2011Date of Patent: December 10, 2013Assignee: Oclaro Technology LimitedInventors: Amyas Daniel Holroyd, Anthony George Foster, Robert Griffin

Patent number: 8213806Abstract: A method of transmitting a plurality n data streams comprises modulating an optical carrier using differential M-ary phase shift key (DMPSK) signalling in which M=2n. Advantageously the method comprises using differential quaternary phase shift keying in which n=2. A particular advantage of the method of the present invention is that since the data is differentially encoded in the form of phase changes rather than absolute phase values this enables the modulated optical carrier to be demodulated using direct detection without requiring a phase-locked local optical oscillator. The invention is particularly applicable to WDM communication systems.Type: GrantFiled: June 8, 2009Date of Patent: July 3, 2012Assignee: Oclaro Technology LimitedInventor: Robert Griffin
