Latest Patents

Randall R Hillock holds a patent for a "Frequency offset method and apparatus for use in a transceiver." This invention is designed for use in a TDD radiotelephone communication system. The radio frequency transceiver includes a local oscillator that generates at least two local oscillator signals at different times, each with a unique frequency. During the first time period, the transceiver receives a radio frequency signal, which is combined with one of the local oscillator signals to form an intermediate frequency signal. In the second time period, the transceiver generates a frequency offset signal that is combined with the second local oscillator signal to create a second radio frequency signal. This innovative design helps to avoid the self-quieting problem inherent in TDD communication systems.
