| 20100117757 | COAXIAL WAVEGUIDE CONVERTER AND RADAR INSTRUMENT - A coaxial waveguide converter is disclosed. It includes a waveguide to which a high frequency signal is transmitted, a coaxial line having an inner conductor that is coupled to the waveguide so as to project an end of the inner conductor into the waveguide, and a first adjustment conductor provided on the periphery of the projected end part of the inner conductor so as to be movable in the axial direction of the inner conductor. | 05-13-2010 |
| 20110037532 | MULTILAYER MICROSTRIPLINE TRANSMISSION LINE TRANSITION - A microstripline transmission line arrangement carries a signal having a fundamental frequency. The arrangement includes a first microstripline transmission line, a second microstripline transmission line, and a coaxial electrically conductive conduit interconnecting the first transmission line and the second transmission line. The conduit includes a signal conductor and an electrically grounded shield substantially surrounding the signal conductor. The conductor and the shield are positioned relative to each other to thereby comprise a means for lowpass filtering the signal. A cutoff frequency of the lowpass filtering is less than a third harmonic of the fundamental frequency. | 02-17-2011 |
| 20110298558 | Folded Monopole Variable Signal Coupler - A signal coupler for coupling wireless signals out of and into a waveguide system is described. The signal coupler includes an input output connector, an outer conductor coupled to the input output connector, and a radiator section, wherein the radiator section is configured to rotate about a center axis of the outer conductor. A wireless distribution system, including a waveguide with a hollow cross-sectional structure and a signal coupling device, is also described. A wireless distribution system, including a waveguide with a hollow cross-sectional structure and a plurality of signal coupling devices, is also described. A method of operating a wireless distribution system is also described. The method includes providing a wireless distribution system and inserting a first group of wireless signals in a preselected bandwidth into the waveguide. | 12-08-2011 |
| 20130063222 | RADIO-FREQUENCY TRANSMITTER, SUCH AS FOR BROADCASTING AND CELLULAR BASE STATIONS - An RF circuit having a transcoupler, a multifunctional RF-circuit element that can operate both as an impedance inverter and as a signal coupler. When connected to a fixed load impedance, the transcoupler can also operate as an impedance transformer. The impedance-transformer/inverter functionality of the transcoupler can be used, e.g., to modulate the load of a power amplifier. The signal coupler functionality of the transcoupler can be used, e.g., to generate a corresponding feedback signal indicative of phase and/or amplitude distortions in the amplifier. The use of various embodiments of the transcoupler in an RF circuit can be advantageous, for example, because the transcoupler has a lower insertion loss than a cascade consisting of a prior-art impedance inverter and a prior-art directional coupler, occupies a relatively small area on the printed circuit board, and helps to reduce the per-unit fabrication and operating costs. | 03-14-2013 |

| 20160064796 | FEED NETWORK FOR ANTENNA SYSTEMS - A feed network for an antenna system having a waveguide is disclosed. The waveguide has broad sides facing each other and narrow sides facing each other. The feed network includes a first microstrip conductor including a first conductor loop and a second microstrip conductor including a second conductor loop. The first and second conductor loops each extend into the waveguide from one of the narrow sides and are each electrically coupled to one of the broad sides. | 03-03-2016 |
