Patent number: 6549103Abstract: The present invention relates to a device at filters for filtering unwanted signals from radio transmitters and/or for use during combination of radio transmitters. Said filter (1) has at least one cavity (2 and/or 3) for filtering radio signals. At least one compensating means (13 and/or 16) is provided to compensate for deviations in frequency depending on expansion or contraction of the cavity (2 and/or 3) due to expansion or contraction of the filter (1) when said filter is heated or cooled during operation. The filter (1) has at least one cavity (2 and/or 3) which is designed for simultaneous filtering of radio signals of at least three different modes (A, B and C and/or D, E and F) and the same frequency. The compensating means (13 and/or 16) is provided in said cavity (2 and/or 3) for compensating deviations in frequency by simultaneously affecting the radio signals of the at least three different modes (A, B and C and/or D, E and F).Type: GrantFiled: March 29, 2001Date of Patent: April 15, 2003Assignee: Teracom Components ABInventor: Ju Jilong

Patent number: 6231261Abstract: The present invention relates to a clamp (1) for clamping or bracing high-frequency cables (2 and/or 3). The clamp (1) comprises an indicating device (21) that determines whether a spring (12) on the clamp (1) has been brought to exert the desired pressure or tensional force during assembly and maintain said desired pressure or tensional force thereafter.Type: GrantFiled: September 18, 1997Date of Patent: May 15, 2001Assignee: Teracom Components ABInventor: Hans Olof Lundbäck

Patent number: 6133532Abstract: A contact device for high-frequency cables including a front member (11) and a rear member (10). The rear member (10) is mounted on the high-frequency cable (1) and the front member (11) is brought in contact with an outer conductor (3) and an inner conductor (5) on the high-frequency cable (1) for transmission of high-frequency signals from the outer and inner conductor (3, 5) to the front member (11). The front member (11) and the rear member (10) are joined to a connector unit (42) in which the front member (11) and the rear member (10) are joined to a connector unit (42) in which the front member (11) is situated in a ready position (P) relative to the rear member (10), the said connector unit (42) can be mounted on the high-frequency cable (1) such that the cable (1) protrudes into the rear member (10).Type: GrantFiled: February 10, 1999Date of Patent: October 17, 2000Assignee: Teracom Components ABInventors: Hans Lundback, Per Thorsson

Patent number: 5654722Abstract: The invention relates to a device at antenna systems for generating radio waves, including a supporting structure mounting at least one main radiator (3) for transmitting radio waves and where high frequency electric currents are generated in the supporting structure when the main radiator (3) is transmitting the radio waves. In order to improve the range of the main radiator (3) and at the same time reduce its backward radiation, the supporting structure includes a secondary radiator (14) for each main radiator (3). The secondary radiator (14) has at least one break portion (12) for interrupting or breaking the high frequency currents generated therein and through the thereby interrupted flow of the high frequency currents in the supporting structure reduce deviations from the desired range and/or direction of the radio waves transmitted by the main radiator (3).Type: GrantFiled: December 11, 1995Date of Patent: August 5, 1997Assignees: Teracom Components AB, Antel Sweden ABInventors: Hans Olof Lundback, Stefan Georg Eriksson
