    摘要: An apparatus for providing a multi-mode interface between a baseband receiver and radio frequency (RF) circuitry. According to a preferred embodiment of the invention, the apparatus includes a first differential-to-single-ended converter, a second differential-to-single-ended converter and an analog-to-digital converter. The first differential-to-single-ended converter receives an incoming differential current pair to be converted into a first single-ended voltage signal. The second differential-to-single-ended converter receives an incoming differential voltage pair to be converted into a second single-ended voltage signal. Further, the analog-to-digital converter selectively receives an incoming single-ended voltage signal, the first single-ended voltage signal, or the second single-ended voltage signal to be converted into a digital signal to be further processed by the baseband processor. Note that the incoming single-ended voltage signal, as well as the incoming differential voltage and current signal pairs together form the multi-mode interface to the RF circuitry.

    摘要: A preferred embodiment of the invention advantageously provides a method for integrating a plurality of radio systems in a unified transceiver structure and the device of the same. According to this general embodiment of the invention, all components for the necessary communication protocols of a device are determined by selecting the operation ranges of the components and designing a mechanism to adjust the operation parameters of the shared components for conforming to the utilized communications system. Therefore, only one radio frequency (RF) module is required for a communications device having a plurality of communication systems. An end user can advantageously carry a single and compact wireless device for various communications systems.

    摘要: A layout of a wireless communication circuit on a printed circuit board (PCB), which is a rectangular board wherein a first side is a Y-axis and a second side is an X-axis. The layout has a first antenna located at a corner between the first side and the second side. An antenna switch and a first filter are located at middle y-coordinate and a X-coordinate. A RF integrated circuit (RFIC) is located after the first filter. A first regulator is located near the second side and higher than the RFIC. A media access control (MAC) is located at about a middle y-coordinate and higher than the first regulator. An oscillator is located at a corner between the second side and the third side. A second regulator is located near the fourth side and above the first regulator. A power amplifier is located near the fourth side above the RFIC. A second filter and a transmitting/receiving (T/R) switch are located before the power amplifier. A second antenna is located at a corner between the first side and the fourth side.
