    • 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.

    • A method is disclosed for operating a multi-mode mobile station, wherein each mode shares at least one common band of frequencies. The method includes transmitting a signal from a first antenna circuit of the mobile station in the common band of frequencies and, while transmitting, electronically detuning a second antenna circuit of the mobile station such that the second antenna circuit is not resonant in the common band of frequencies. As an example, the common band of frequencies includes 1900 MHz. The step of detuning includes varying an impedance of at least one component that forms a part of the second antenna circuit, where the at least one component can be a stripline or a PIN diode of a FET diode uses as switch for making an impedance change. The at least one component can also be a normally active component that is put into a passive state. A multi-mode mobile station in accordance with these teachings has, for each mode, a transmitter chain that includes an antenna circuit that operates in the common band of frequencies and a controller, that is responsive to a first one of the transmitter circuits transmitting, for electronically detuning a second antenna circuit of the mobile station such that said second antenna circuit is resonant at a frequency that lies outside of, or that is shifted away from, the common band of frequencies.

    • A device that has an antenna and an internal RF circuit is connected by an electrical conductor that has a first portion coupled to the RF circuit and an opposed, flexibly resilient second portion. The second portion defines a contact point and a testing point. The contact point is normally electrically coupled to the antenna by a bias in the second portion. When a biasing force such as a RF testing probe exerts force on the testing point through an aperture of a device housing, the normal bias of the second portion is overcome and contact is temporarily interrupted between the antenna and the contact point. The RF probe is placed in electrical contact with the RF circuit by contact with the testing point, which may be directly when a cover over the aperture is removable, or via a conductive pathway imposed through a flexible membrane that is fixed to the housing as a cover over the aperture.
