Patent number: 9113420Abstract: A radio system (110) comprising a first (120) and a second (130) radio unit which comprise a transmitter (122, 132) and a receiver (121, 131). The first radio unit (120) communicates with a first external radio unit (101) and the second radio unit (140) with a second external radio unit (102). Both transmitters (122, 132) are arranged to vary their output power level in response to a request from the external radio unit with which they are arranged to communicate. Both of the transmitters also vary their output power level in response to a variation in the transmitter output power level of the other radio unit.Type: GrantFiled: December 29, 2009Date of Patent: August 18, 2015Assignee: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Dan Rutger Weinholt, Marcus Karl Hasselblad

Patent number: 8598961Abstract: The present invention relates to a transition arrangement comprising two surface-mountable waveguide parts and a dielectric carrier material with a metallization and a ground plane provided on a respective first main side and second main side Surface-mountable waveguide parts comprise a first wall, a second wall, and a third wall, which second and third walls are arranged to contact a part of the metallization, all the walls together essentially forming a U-shape, the surface-mountable waveguide parts also comprising respective bend parts. The metallization on the first main side is removed such that a first aperture and a second aperture are formed, the apertures being enclosed by a frame of via holes electrically connecting the ground plane with the metallization, the bend parts being fitted such that the apertures permit passage of a microwave signal propagating via the bend parts. Then the dielectric carrier material itself acts as a waveguide transition between the first aperture and the second aperture.Type: GrantFiled: April 16, 2008Date of Patent: December 3, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Marcus Karl Hasselblad, Per Ligander, Simone Bastioli, Uwe Rosenberg

Patent number: 8461945Abstract: The present invention relates to a transition arrangement comprising a first surface-mountable waveguide part, a second surface-mountable waveguide part and a dielectric carrier material with a metalization provided on a first main side. Each of the first and second surface-mountable waveguide parts comprises a first wall, a second wall and a third wall, which second and third walls are arranged to contact a part of the metalization, where the first and second surface-mountable waveguide parts are arranged to be mounted on the dielectric carrier material in such a way that the first and second surface-mountable waveguide parts comprise ends which are positioned to face each other. The transition arrangement further comprises an electrically conducting sealing frame that is arranged to be mounted over and covering the ends, where the electrically conducting sealing frame has a first wall, a second wall and a third wall, where the second and third walls are arranged to contact a part of the metallization.Type: GrantFiled: March 27, 2008Date of Patent: June 11, 2013Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Per Ligander, Marcus Karl Hasselblad

Patent number: 8183960Abstract: A waveguide filter comprising a matching means for matching the filter. The waveguide filter comprises a housing comprising a cavity having a predetermined first volume. The matching means is in the form of a volume element having a predetermined second volume being matched to the first volume forming a predetermined volume to volume ratio. The matching means is fitted into the cavity in a fixed non-adjustable manner in relationship to the housing. The invention refers also to a method for manufacturing of such a waveguide filter.Type: GrantFiled: July 13, 2006Date of Patent: May 22, 2012Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Per Ligander, Marcus Karl Hasselblad
