Patent number: 11664812Abstract: An example frequency converter includes a drift canceling loop with a balanced delay and a linear signal path (e.g., linear with respect to frequency scaling, amplitude modulation, and/or phase modulation). One side of the drift canceling loop includes a fixed delay, and the opposite side includes an adjustable, complementary delay. The adjustable, complementary delay facilitates precision matching of the signal delays on each side of the loop over a range of frequencies, which results in a significant improvement in noise cancelation, particularly at large offsets to the carrier, while permitting the use of a higher noise, but very fast tuning course scale oscillator. The linear signal path from the signal generator to an RF output facilitates modulation of the signal by the signal generator. A modular format is an advantageous embodiment of the invention that includes the removal of the frequency synthesizer's low phase noise reference into a separate module.Type: GrantFiled: November 18, 2020Date of Patent: May 30, 2023Assignee: Giga-tronics IncorporatedInventors: John R.

Publication number: 20070183336Abstract: A method and apparatus for managing a loop network, the loop network (200) including at least one loop (206, 208), a plurality of devices (210) connected to the at least one loop (206, 208) via ports (211, 212), wherein at least two of the devices are initiators (207, 209). The method includes each initiator (207, 209) sending a frame to all other initiators (207, 209) in the loop network (200) identifying any ports (211, 212) which should not be used. Each initiator (207, 209) merges the information from all other initiators (207, 209) with its own information identifying any ports (211, 212) which should not be used resulting in all the initiators (207, 209) generating a single list of ports (211, 212) to be used which is consistent across all the initiators (207, 209). Each initiator (207, 209) applies an algorithm (300) to determine a common set of ports (211, 212) to be used by all the initiators (207, 209) and to balance port accesses across the loop network (200).Type: ApplicationFiled: April 16, 2007Publication date: August 9, 2007Inventors: Paul Cashman, Carlos Fuente

Publication number: 20070113033Abstract: An apparatus operable with a host and at least first and second data storage for avoiding overwriting of a stored data item in the second data storage by a copy services system is provided. The apparatus includes a storage use analyzer for determining the availability of the second data storage. A copy services requester communicates with the host to receive a request to establish a copy services relationship, using the second data storage as a target data storage. A request blocking and passing component passes the request to establish a copy services relationship using the second data storage as the target data storage, responsive to a positive determination of availability of the second storage. The request blocking and passing component may also block the request responsive to a negative determination of availability of the second data storage.Type: ApplicationFiled: August 24, 2006Publication date: May 17, 2007Inventors: Carlos Fuente, William Scales

Publication number: 20060206542Abstract: Methods and apparatus are provided for copying data from a primary storage facility to a secondary storage facility which reduce the workload on the storage controller in the primary facility and minimize bandwidth usage. The primary storage facility includes a primary data replication appliance which transfers data to a secondary replication appliance. Updated data from a host is both stored through a storage controller in the primary facility and also received by the primary replication appliance. Logic in the primary replication appliance determines whether the immediately previous version of the data is in a buffer from a previous storage operation. If so, the current (updated) version of the data is compared with the previous version and the difference, such as calculated through a bit-wise exclusive-OR operation, is transferred to the secondary replication appliance.Type: ApplicationFiled: March 14, 2005Publication date: September 14, 2006Applicant: International Business Machines (IBM) CorporationInventors: John Wolfgang, Kenneth Day, Philip Doatmas, Henry Butterworth, Carlos Fuente
