  • Publication number: 20110304012
    Abstract: A semiconductor device has a substrate and RF FEM formed over the substrate. The RF FEM includes an LC low-pass filter having an input coupled for receiving a transmit signal. A Tx/Rx switch has a first terminal coupled to an output of the LC filter. A diplexer has a first terminal coupled to a second terminal of the Tx/Rx switch and a second terminal for providing an RF signal. An IPD band-pass filter has an input coupled to a third terminal of the Tx/Rx switch and an output providing a receive signal. The LC filter includes conductive traces wound to exhibit inductive and mutual inductive properties and capacitors coupled to the conductive traces. The IPD filter includes conductive traces wound to exhibit inductive and mutual inductive properties and capacitors coupled to the conductive traces. The RF FEM substrate can be stacked over a semiconductor package containing an RF transceiver.

  • Patent number: 6993932
    Abstract: A refrigerant cycle system in which the arrangement of a connecting pipe for connection between a compressor and an accumulator is improved effectively to recover oil collected in the accumulator to the compressor. The accumulator is installed to be separate from the compressor. A connecting pipe is arranged between the compressor and the accumulator to feed a refrigerant gas separated in the accumulator to the compressor. An oil recovery hole is provided at an inlet portion of the connecting pipe received in the accumulator such that it is arranged at a level higher than a highest level portion of the connecting pipe located outside of the accumulator. A second accumulator may be connected between the connecting pipe and the compressor while being directly installed at the compressor. In this case, the connecting pipe has an outlet portion connected to the second accumulator.

  • Publication number: 20050085661
    Abstract: The present invention relates to a process for preparing fluoroacrylic acid ester using a pervaporation composite membrane, in particular, to a process for preparing fluoroacrylic acid ester performed in such a manner that water and unreacted fluoroalcohol generated in esterification between fluoroalcohol and (meth)acrylic acid in the presence of an acid catalyst are condensed and then passed through a pervaporation membrane to effectively remove water, followed by recycling the unreacted fluoroalcohol removed of water. The present process exhibits much higher conversion rate of fluoroacrylic acid ester, allows the decrease of energy consumption and could be performed in environment-friendly manner.
