  • Circuit coupling
    Patent number: 8781432
    Abstract: An apparatus for coupling a baseband integrated circuit that uses a first signalling standard to a radio frequency integrated circuit that uses a second signalling standard includes a buffer coupled to the baseband integrated circuit and a resistor network coupled between the buffer and the radio frequency integrated circuit. The resistor network implements a voltage divider so as to convert a first voltage used by the baseband integrated circuit to a second voltage used by the radio frequency integrated circuit. The apparatus may be used in a mobile telecommunications device.
    Type: Grant
    Filed: October 7, 2011
    Date of Patent: July 15, 2014
    Assignee: Broadcom Corporation
