Patent number: 9762251Abstract: A system for providing ultra low phase noise frequency synthesizers using Fractional-N PLL (Phase Lock Loop), Sampling Reference PLL and DDS (Direct Digital Synthesizer). Modern day advanced communication systems comprise frequency synthesizers that provide a frequency output signal to other parts of the transmitter and receiver so as to enable the system to operate at the set frequency band. The performance of the frequency synthesizer determines the performance of the communication link. Current days advanced communication systems comprises single loop Frequency synthesizers which are not completely able to provide lower phase deviations for errors (For 256 QAM the practical phase deviation for no errors is 0.4-0.5°) which would enable users to receive high data rate. This proposed system overcomes deficiencies of current generation state of the art communication systems by providing much lower level of phase deviation error which would result in much higher modulation schemes and high data rate.Type: GrantFiled: December 15, 2016Date of Patent: September 12, 2017Inventors: Yekutiel Josefsberg, Tal I.

Patent number: 7809324Abstract: Method and apparatus for determining the efficiency of publicity and/or broadcasted programs, according to which, when a TV converter or FM radio is operated, the frequency of the broadcast channel received at the moment is determined either directly from the TV converter or FM radio display or by extracting the LO frequency of the TV converter or FM radio. The frequency is transformed to a digital word and when the information as to the amount of watching and listening of a given publicity and/or broadcasted program or publicities is desired, a request for the information is sent and when received, the memorized digital words corresponding to the frequency of the broadcast channel received at the moment is transmitted.Type: GrantFiled: January 13, 2005Date of Patent: October 5, 2010Assignee: Future Wireless Ltd.Inventor: Yekutiel Josefsberg

Patent number: 4614917Abstract: There is provided an indirect frequency synthesizer in the millimeter wave frequency range of 36 to 38.6 GHz. The synthesizer comprises a high performance frequency translation loop for operation in the microwave frequency range and contains a voltage-controlled oscillator, an automatic loop gain correction system and a sophisticated lock search system. The frequency translation loop is operable under a variety of conditions (temperature etc.) and overcomes the considerable difficulties which exist in this frequency range such as maintenance of constant optimum loop parameters, thus making it possible to utilize the entire frequency tuning range of the millimeter wave oscillator. As a result, the synthesizer has very satisfactory characteristics as regards noise and spurious frequencies products.Type: GrantFiled: April 17, 1985Date of Patent: September 30, 1986Assignee: Tadiran Ltd.Inventors: Michael Zelitzki, Yekutiel Josefsberg
