    摘要: Over the air or radiated testing of an RF microelectronic or integrated circuit device under test (DUT) that has an integrated millimeter wave (mmw) antenna structure, is described. The antenna structure may have multiple elements in an array design that may be driven and/or sensed by integrated RF transmitter and/or receiver circuitry. An interface printed wiring board (e.g., a tester load board or a wafer probe card assembly) has formed in it a mmw radiation passage that is positioned to pass mmw radiation to and/or from the integrated antenna of the DUT. Test equipment may be conductively coupled to contact points of the interface board, to transmit and/or receive signals for testing of the DUT and/or provide dc power to the DUT. A test antenna is designed and positioned to receive and/or transmit mmw radiation through the passage, from and/or to the integrated DUT antenna. Other embodiments are also described and claimed.

    摘要: A method of scaling at a receiver representations of training signals received from a transmitter. The method includes producing a frequency domain representation of at least one long training symbol received at the receiver and a frequency domain representation of a data symbol, and scaling the frequency domain representation of the at least one long symbol based on a largest coefficient in the frequency domain representation to produce a scaled frequency domain representation of the at least one long symbol.

    摘要: A media access controller (MAC) generates a composite packet having an optimized format for carrying audio, video, and data traffic. A header portion of the composite packet is encoded separately from a data portion of the composite packet. A physical device interface (PHY) is coupled to the MAC. The PHY encodes and decodes between a digital signal and a modulated analog signal. The PHY comprises a high rate physical layer circuit (HRP) and a low rate physical layer circuit (LRP). A radio frequency (RF) transmitter is coupled to the PHY to transmit data.
