Patent number: 9391665Abstract: Embodiments provide a method and apparatus for performing time division duplex communication, such as may be performed over a wireless communications network. In the embodiments a first circuit pathway is used to transmit a first radio frequency signal in a transmission mode and a second circuit pathway is used to receive a second radio frequency signal in a reception mode. In the reception mode, the first radio frequency signal is switched to an alternate circuit pathway. This may be performed by a radio frequency integrated circuit or by other control circuitry. Switching to an alternate circuit pathway reduces leakage of the first radio frequency signal into the second radio frequency signal.Type: GrantFiled: April 11, 2014Date of Patent: July 12, 2016Assignee: BROADCOM CORPORATIONInventors: Lauri Niskanen, Seppo Rousu, Juha Valtanen

Patent number: 8761709Abstract: A receiver 650 operates in close proximity to at least one other component 610, 611, 612 causing interferences in signals received by the receiver 650. It is determined (steps 2002; 2003) whether and at which frequency a higher harmonic of and/or an inter-modulation product with signals generated by the other component 610 causes interference in signals received by the receiver 650, based on information about signals generated by the other component 610, 611, 612. At least one characteristic of the receiver 650 is adjusted to diminish an influence by a determined interference.Type: GrantFiled: March 1, 2006Date of Patent: June 24, 2014Assignee: Nokia CorporationInventors: Marko Leinonen, Juha Valtanen, Seppo Rousu

Patent number: 8416758Abstract: A reconfigurable radio frequency circuit is configurable to a first mode when first and second radio frequency signals are within a first frequency band, and to a second mode for use when the first but not the second signal is in the first band. A first signal divider operating in the first band provides a first signal division ratio in the first mode and a second ratio in the second mode. In the first mode, a first output of the signal divider is connected by a first switch to a first receiver and the second output is connected by a second switch to a second receiver. In the second mode, the first output is connected by the first switch to the first receiver and a second divider operating in a second band is connected by the second switch to the second receiver.Type: GrantFiled: November 8, 2012Date of Patent: April 9, 2013Assignee: Renesas Mobile CorporationInventors: Seppo Rousu, Juha Valtanen
