Patent number: 8958694Abstract: One or more overlay wavelengths are applied to a GPON architecture to provide sufficient, cost-effective forward bandwidth per home for targeted, unique narrowcast services to allow traditional HFC operators to use a PON architecture with their existing HFC equipment. A separate return path capability using a separate coaxial cable with RF signals to the GPON may also be used. This return capability may be provided either by a fiber optic link or coaxial link from the home.Type: GrantFiled: March 5, 2013Date of Patent: February 17, 2015Assignee: General Instrument CorporationInventors: Philip Miguelez, Shawn M.

Patent number: 8869223Abstract: In general, in one aspect, the disclosure describes a resonance restricting material in communication with a bypass line of a cable television tap. The bypass line generates resonances at a defined frequency in response to RF parameters in the tap and the resonances increase insertion losses at the defined frequency and precludes bandwidth of the tap being increased above the defined frequency. The resonance restricting material may attenuate the resonances generated by the bypass line at the defined frequency (e.g., approximately 1.2 GHz) and reduce insertion losses at the defined frequency and enable the bandwidth of the tap to be increased (e.g., from 1.0 GHz to 1.8 GHz).Type: GrantFiled: March 15, 2013Date of Patent: October 21, 2014Assignee: General Instrument CorporationInventors: Rudolph J. Menna, Philip Miguelez

Publication number: 20080095539Abstract: The present invention allows an operator to individually control the power level of each communication channel in a network without affecting other parameters of the channels. Each optical transmitter contains a voltage controlled variable optical attenuator which is controlled by a microcontroller to attenuate the optical communication signal to a desired level. The operator can adjust each transmitter separately to overcome the variability in the output optical power of each transmitter, the flatness of the WDM component, EDFA flatness, dispersion of the fiber, etc.Type: ApplicationFiled: October 24, 2006Publication date: April 24, 2008Applicant: GENERAL INSTRUMENT CORPORATIONInventors: Ihab E.

Patent number: 6865199Abstract: A method is provided for using an uncooled laser package having pre-established performance specifications that include a pre-established optical power level. The package is to be used at a second set of performance specifications that include a second optical power level greater than the preestablished optical power level. The method begins by applying a bias level to a laser diode in the uncooled laser package that optimizes distortion and causes the laser package to generate the second optical power level. The bias level is greater than a pre-established bias level specified to generate the pre-established optical power level. Next, the uncooled laser package is heated or cooled to maintain a substantially constant laser diode temperature.Type: GrantFiled: July 29, 2002Date of Patent: March 8, 2005Assignee: General Instrument CorporationInventors: Philip Miguelez, Shutong Zhou, Richard A.

Publication number: 20030063637Abstract: A method is provided for maintaining the temperature of a laser diode located in a laser package. The method begins by monitoring a photocurrent generated by a photodiode that collects light from a back-facet of the laser diode located in the laser package while maintaining a constant bias level to the laser diode. Next, the laser diode is heated or cooled to maintain a substantially constant photocurrent, thereby maintaining the temperature of the laser diode at a substantially constant value. The laser package may be an uncooled laser package such as a coaxial can laser package.Type: ApplicationFiled: July 29, 2002Publication date: April 3, 2003Inventors: Philip Miguelez, Shutong Zhou, Richard A.

Patent number: 6239668Abstract: The RF transformer of the present invention couples a transmission line between a magnetic transformer and a balun. The location and function of the transmission line improves frequency response across a wide operational bandwidth by permitting the circuit to be tuned, thereby providing a greater degree of impedance matching.Type: GrantFiled: April 14, 1999Date of Patent: May 29, 2001Assignee: General Instrument CorporationInventors: Rudolph Menna, Philip Miguelez

Patent number: 6107877Abstract: An in-line distortion generator is coupled to an RF amplifier on a single PC board for producing an output signal of useful amplitude but with low composite triple beat and cross modulation distortions. The backplane under the section of the PC board upon which the distortion circuit resides is removed and the portion of the heat sink under the removed portion of the backplane is also removed. This eliminates any parasitic capacitances that could degrade the performance of the RF amplifier, thereby making the distortion circuit transparent to the RF amplifier. Furthermore, the layout of the predistortion circuitry has been specifically designed to enhance the performance of the circuitry without inducing any negative operating characteristics on the associated RF amplifier.Type: GrantFiled: April 9, 1999Date of Patent: August 22, 2000Assignee: General Instrument CorporationInventors: Philip Miguelez, Rudolph Menna, Shutong Zhou, Timothy Cope

Patent number: 6107885Abstract: The present invention incorporates GaAs field effect transistors (GaAsFETs) in a radio frequency (RF) ultra-linear amplifier. The described amplifier circuit is a transformer-coupled single input, signal processing unit incorporating ultra-fast, GaAsFETs in a three active device cascode. This arrangement allows for a higher working voltage to be applied across the three semiconductors rather than a traditional two transistor cascode. The operational bandwidth can process a mixed modulation signal comprised of analog and digital channels.Type: GrantFiled: January 25, 1999Date of Patent: August 22, 2000Assignee: General Instrument CorporationInventors: Philip Miguelez, Rudolph J.
