    Abstract: Disclosed are embodiments of a transceiver front-end configured for a reduced noise figure (NF). Each of the embodiments includes an antenna, a transmitter branch and a receiver branch all connected to an input/output pad. The transmitter branch is coupled to the input/output pad (and thereby the antenna) by an impedance transformer. Only the receiver branch is selectively electrically connected to the input/output pad (and thereby the antenna) by a switch. A common matching network between the input/output pad and the switch provides both impedance matching and electrostatic discharge protection for the switch and the low noise amplifier, thereby reducing NF. Specific embodiments are disclosed for integration into specific technologies (e.g., fully depleted silicon-on-insulator (FDSOI) technology and fin-type field effect transistor (finFET) technology).

  • Patent number: 10134518
    Abstract: Radio frequency (RF) transmission line transformers are disclosed. Unlike conventional transformers that employ magnetic cores that transmit energy from input to output through magnetic flux linkages, the embodiments of the RF transmission line transformer disclosed herein transfer energy by configuring transformer coils as balanced transmission lines. More specifically, the RF transmission line transformers have a primary transformer coil that forms at least one primary winding and a secondary transformer coil that forms at least a pair of secondary windings. The primary winding of the primary transformer coil is disposed between the pair of secondary windings so that the primary winding forms a different balanced transmission line with each one of the pair of secondary windings. This results in greater bandwidth and higher transformer power efficiency (TPE) at RF frequencies.

  • Patent number: 8975997
    Abstract: In a planar coil element, the quantitative ratio of inclined particles to total particles of a first metal magnetic powder contained in a metal magnetic powder-containing resin provided in a through hole of a coil unit is higher than the quantitative ratio of inclined particles to total particles of the first metal magnetic powder contained in the metal magnetic powder-containing resin provided in other than the through hole, and many of particles of the first metal magnetic powder in the magnetic core are inclined particles whose major axes are inclined with respect to the thickness direction and the planar direction of a substrate.

  • Patent number: 8964410
    Abstract: A transformer has two magnetic cores, at least one primary winding unit mounted in the magnetic cores, at least one secondary winding unit mounted in the magnetic cores and two rectifying circuit boards externally mounted beside the magnetic cores. An AC voltage output from the secondary winding unit is transmitted to and rectified by the rectifying circuit board. Therefore, the size of the transformer is compact, and heat energy generated by electronic elements mounted on the rectifying circuit board is effectively dissipated to maintain normal operation of the transformer. Further, since the transmission path from the secondary winding unit to the rectifying circuit board is short, energy loss is reasonably reduced when the transformer is operated under a high frequency situation or a larger current mode.
