The invention relates to an integrated Doherty amplifier with an input network connecting the input to the main stage and to the peak stage, and with an output network connecting the main stage and the peak stage to the output. The output network has a shunt capacitor to signal-ground in parallel to a parasitic capacitance of the main stage, and has a shunt inductor between the main stage and signal ground. The shunt configuration enables to use the MMIC Doherty amplifier in a wide frequency range. At least some of the inductors of the input network and / or output network are implemented using bond wires. Their orientations and locations provide minimal mutual electromagnetic coupling between the wires and the return RF current paths.

The invention discloses a corner-cutting circuit in an LCD (Liquid Crystal Display) driving system, which is connected with a plurality of scanning-line driving circuits and comprises a charging circuit, a plurality of discharging modules and a plurality of external adjusting modules, wherein the charging circuit is integrated on a control plate and is used for receiving the input of a direct-current driving voltage and outputting an opening voltage for charging the scanning-line driving circuits; the discharging modules are respectively integrated on each scanning-line driving circuit and are used for controlling the corresponding scanning-line driving circuit to be discharged; and the external adjusting modules are respectively and externally connected to the external part of each scanning-line driving circuit, are connected with the corresponding discharging modules and are used for adjusting the discharging modules to control the discharging speeds of the scanning-line driving circuits. In the invention, the size of a variable resistor which is externally connected onto a discharging resistor is regulated according to the size of the respective parasitic capacitor of each scanning-line driving circuit to further adjust the discharging slope of the corresponding scanning-line driving circuit, so that the corner-cutting circuit is applicable to the scanning-line driving circuits with different parasitic capacitors.

A system and method for providing a global positioning system (GPS) enabled antenna system are provided. The GPS enabled antenna may be used, for example, on a wireless communications device such as a wireless handset. The wirelesscommunications device includes a GPS switching module coupled to a conventional communications antenna, including its associated circuitry. The GPS switching module is adapted to selectively couple the communications antenna to GPS matching circuitry. In this arrangement, the GPS matching circuitry adjusts impedance at approximately 1575 MHz to more closely match the communications antenna to GPS circuitry in the wireless device.

The present invention provides for a method, system, and computer program product for managing the storage of data. Data is selectively compressed based on a pre-defined compression policy and metadata is stored for physical storage blocks. A stored compression policy identifies at least one criterion for compression, and physical blocks of data meeting the compression policy are identified. A physical block is selected as a source block for data compression, and one or more physical locations are selected as target locations. Data is read from the source block, compressed, and written to the target locations. Metadata is updated to indicate a mapping between the target locations and the virtual blocks previously mapped to the source block. Extra storage capacity can be freed up until more physical storage is ordered and installed, while more important data, such as recently or frequently accessed data, is retained in an uncompressed and accessible state.

A complex antenna has a first antenna element and a second antenna element each connected at one end to a different feed point and connected to each other at the other end through a parallel resonant circuit. Each antenna element has the same resonant frequency as the parallel resonant circuit. A mobile phone has an antenna switch with a first port connected to the first antenna element, a second port connected to the second antenna element, and a third port that can be connected to one of the first port and the second port and switched therebetween. A signal processing unit causes the antenna switch to connect the third port to the first port or to the second port and detects a signal captured by one of the antenna elements from the output of the third port.
