Latest Patents
One of Hongo's latest patents is a mobile communication apparatus that features a transceiver suitable for larger scale integration. This invention employs direct conversion reception to reduce the number of filters required. Additionally, the number of Voltage-Controlled Oscillators (VCOs) is minimized by utilizing dividers to supply both a receiver and a transmitter with locally oscillated signals at an RF band. Fixed division ratio dividers are used for generating locally oscillated signals for the receiver, while a switchable division ratio divider is employed for the transmitter. Furthermore, a variable gain amplifier for baseband signals is equipped with a DC offset voltage detector and a DC offset canceling circuit. This design supports high-speed data communications by enabling fast cancellation of a DC offset, thus eliminating the need for a filter within the feedback loop for offset cancellation.
