摘要： Embodiments of this disclosure may include a receiver with a reconfigurable processing path for different signal conditions. Such a receiver may reconfigure between a mixer-first configuration and an amplifier-first configuration. In the mixer-first configuration, an RF input signal is not passed through an LNA for amplification before processing the RF input signal for downconversion to baseband and eventual extraction of the information in the signal. In the amplifier-first configuration, an RF input signal is passed through an LNA for amplification before processing the RF input signal for downconversion to baseband and eventual extraction of the information in the signal. Reconfiguring the receiver between mixer-first and amplifier-first configurations may be performed based on detection of jammer signals and/or measurement of signal-to-noise ratio (SNR).

摘要： The present disclosure provides a method and a dual band receiver for handling an analog dual band radio signal comprising a first frequency band component and a second frequency band component. The method comprises sampling the analog dual band radio signal through the use of interleaving analog-to-digital converters, ADCs, to obtain four sampled signals including a first I component, Iin+, a first Q component, Qin+, a second I component, Iin−, and a second Q component, Qin−, wherein phases of Qin+, Iin− and Qin− are respectively offset with respect to phases of Iin+, Qin+ and Iin− by π/2. Then, the four sampled signals are filtered through the use of polyphase filters to obtain a first set of filtered signals (a1, a2, a3, a4) each of which has a same power as the first frequency band component and a second set of filtered signals (b1, b2, b3, b4) each of which has a same power as the second frequency band component. Subsequently, a power of the first frequency band component, a power of the second frequency band component and a total power of the first frequency band component and the second frequency band component are estimated, based on the four sampled signals, the first set of filtered signals and the second set of filtered signals. Next, the first frequency band component and the second frequency band component are selectively attenuated based on the estimated powers.

摘要： Embodiments of a variable inductor and a communication device are generally described herein. The variable inductor may comprise a signal wire and a control wire to receive a direct current (DC) control current. The variable inductor may further comprise a magnetic material integrated with the signal wire and the control wire. When a DC control current applied to the control wires takes a first current value, an inductance between an input node and an output node on the signal wire may take a first inductance value. When the DC control current takes a second current value, the inductance between the input node and the output node may take a second inductance value.

摘要： Disclosed are systems and methods for reducing filter insertion loss while maintaining out-of-band attenuation. In some embodiments, a system can be configured for processing of radio-frequency (RF) signals. The system can include a plurality of signal paths configured to accommodate multiple frequency bands, with each of the multiple bands having a passband. The system can further include a filter circuit disposed along each of the signal paths. At least one of the filter circuits can be segmented into two or more segments that substantially cover the passband corresponding to the filter circuit. The segmented filter circuit can be configured to provide a desired attenuation of out-of-band interferers and a desired insertion loss level. In some embodiments, the signal paths can include receive (Rx) paths.
