Patent number: 7403747Abstract: A method of tuning a station is disclosed, wherein a first pilot signal is applied on a circuit of the station and the resulting output power of the signal circuit is subsequently detected. A second pilot signal is then applied to the circuit and the resulting output power of the circuit is detected. The offset of the circuit is then tuned based on information of the resulting output power detected for the first and second signals. A station that is adapted to implement the method may be tuned by the manufacturer thereof or later after having already been taken into use. The tuning may occur automatically as response to a predefined event.Type: GrantFiled: June 27, 2002Date of Patent: July 22, 2008Assignee: Nokia CorporationInventors: Tapio Kuiri, Ville Salmi, Jorma Savolainen

Patent number: 7062248Abstract: A wireless communications mobile station (10) includes at least one antenna (240) and a RF transceiver (210,220) containing a direct conversion receiver (1) coupled to the antenna. The direct conversion receiver contains a low noise amplifier (3) for amplifying a received RF signal and for outputting the amplified RF signal to a current switching down-conversion mixer (4). The down-conversion mixer has a first input node for receiving the amplified RF signal, a second input node for receiving a local oscillator (LO) signal for mixing with the amplified RF signal and an output node coupled to an input of an operational amplifier forming a low pass filter (5A). In accordance with an aspect of this invention the low pass filter has a low pass pole generated by a resistor R and a capacitor C coupled in parallel in a feedback path of the operational amplifier, where a low pass comer frequency of the low pass filter is inversely proportional to the product of R and C.Type: GrantFiled: January 16, 2003Date of Patent: June 13, 2006Assignee: Nokia CorporationInventor: Tapio Kuiri

Patent number: 7043242Abstract: A method and device for avoiding adjacent channel interference and reducing disconnections caused thereby, during communication between a mobile device and a base station in a wireless telecommunications network. The mobile device measures the strength of a received signal before the signal enters one or more selected filters, and compares the strength of the signal after the filtering, in order to estimate a power ratio of the adjacent channel interference to communication channel power. If the power ratio is greater than a threshold, then a handover is requested to an alternative communication channel available between the mobile device and either the base station or another base station.Type: GrantFiled: January 31, 2001Date of Patent: May 9, 2006Assignee: Nokia CorporationInventors: Tapio Kuiri, Harri Lilja, Jussi Numminen, Kaj Jansen, Sami Haapoja

Patent number: 6798294Abstract: A low noise amplifier (500) is provided for amplifying signals in a frequency band. The low noise amplifier (500) comprises several amplifying elements (505, 506) that share a load impedance (503) and a degeneration impedance (504). One of the amplifying elements (505, 506) is activated at a time that the rest are deactivated. The activation and deactivation is done by feeding a bias to a bias port (501, 507) or grounding the same, respectively. A signal to be amplified is fed to the corresponding input (511, 512) depending on which of the amplifying elements (505, 506) is activated. An amplified signal is obtained at an output (513).Type: GrantFiled: September 13, 2002Date of Patent: September 28, 2004Assignee: Nokia CorporationInventor: Tapio Kuiri
