摘要： A transistor switch that provides isolation is described. The transistor switch is adapted to receive an input signal at an input terminal and either transmit the input signal to an output terminal when the transistor switch is in a first state or ground the input signal when the transistor switch is in a second state. The transistor switch comprises series switches, which couple the input terminal to the output terminal when the transistor switch is in the first state; shunt switches, which couple the input terminal to ground when the transistor switch is in the second state; and filters to provide isolation between the input terminal and the output terminal.

摘要： A doubly balanced transceiver system having a transmit terminal (TX), a receive terminal (RX), and an an antenna terminal (ANTENNA), 180° hybrids (201, 240), 90° hybrids (204, 304, 235 and 335), a power amplifier (230, 330) and a RX/TX switch (220) for disabling the power amplifier so that signals received at the transmitter are reflected to the receive terminal (RX). The 180° hybrids (201, 240) preferably split and re-combine signals into parallel paths. A loopback test mode is preferably provided by use of an antenna isolation switch (302) to enable a power detect terminal (POWER_DETECT). This eliminates pricey and problematic GaAs switches, and allows the use of low cost silicon for the power amplifier. The doubly balance architecture also has the advantage of eliminating common-mode noise, and reflection problems with the PA gain stages. Additionally, greater power can be extracted from the power amplifier. Further the arrangement has less insertion loss compared to a GaAs switch. Also, dependant upon system specifications, it may be possible to eliminate harmonic filtering at the power amplifier output.

摘要： Driver circuits and methods related thereto for driving high power and/or high frequency devices are described. The driver circuits comprise transistor stacks and capacitors coupled with the transistor stacks. Voltages across the capacitors depend on state (on or off) of each transistor in the transistor stacks. These voltages in turn determine output voltages generated by the driver circuits.

The charge pump includes a first level translator (131) that monitors a high range of an output voltage (156) of the differential current amplifier and self-adjusts the first bias point to extend the output voltage to a higher range, and a second level translator (132) that monitors a low range of the output voltage of and self-adjusts the second bias point to extend the output voltage to a lower range. The charge pump keeps the output current constant between the higher range and the lower range. A sensing transistor increases an output impedance of the differential current amplifier and reduces output loading.

摘要： A method and apparatus for wirelessly transmitting data between two devices (101. 102) is provided herein. During data transmission, a data and a strobe signal are transmitted simultaneously on the I and Q-channels, respectively, of over-the-air interface. More particularly, QPSK modulation is utilized, with the strobe signal being transmitted via the I-channel, and the data signal being transmitted via the Q channel, (or vice versa). Additionally, illegal constellation transitions are utilized to signal the transmission of control information.
