摘要： A method is disclosed of a communication device adapted to process a received signal using either of a first channel selection filter and a second channel selection filter, where the received signal comprises signal entities each representing an individually processed block of data. The method comprises (during use of the first channel selection filter) detecting a presence of an interference signal outside a pass band of the first channel selection filter and switching to use of the second channel selection filter in response to detecting the presence of the interference signal. The method also comprises (if the switching occurs at a first point in time within a first signal entity dividing the first signal entity into a first part and a second part) applying a time domain compensation filter to one of the first part and the second part of the first signal entity. Corresponding computer program product, receiver arrangement and communication device are also disclosed.

摘要： An inductor that adjust characteristics of a transmit filter circuit is disposed so that the inductor and at least one of common paths, a matching circuit, a receive filter circuit, and receive paths connected to an output terminal of the transmit filter circuit define a propagation path due to magnetic-field coupling and/or electric-field coupling. This configuration does not require the addition of a circuit device to define the propagation path. It is thus possible to improve attenuation characteristics for an RF signal outside the frequency band of a transmitting signal and to improve isolation characteristics between a transmit filter circuit and a receive filter circuit without increasing the size of a radio-frequency module.

摘要： A filter assembly is provided comprising a first filter (12), a notch filter (26, 26′), and a phase-shifter (36). The first filter has a stop-band. The filter assembly is configured to, in use, split the output of the first filter into a main signal on a first path (18, 20, 22) and a secondary signal on a parallel path (26, 36, 38), and to pass the signal on the parallel path through the notch filter (26) having a stop-band corresponding to the pass-band of the first filter and, or including, through the phase-shifter (36) so as to be phase-shifted at least substantially into anti-phase to the main signal to provide an adjustment signal Φf(ω). The filter assembly is further configured to combine (22) the adjustment signal with the main signal so as to provide the main signal attenuated in the stop-band.

摘要： A system/method describing a physically compact broadband radio frequency (RF) splitter/combiner is disclosed. The system and method provide an alternative to traditional broadband Wilkinson-style RF power splitter/combiners while reducing the overall size of the power divider/combiner to a significantly smaller form factor. The system and method utilize a serpentine impedance network (SIN) that incorporates a mirrored series of positive serpentine node (PSN) traces and negative serpentine node (NSN) traces. The PSN and NSN are coupled together within each isolated and mirrored SIN section with paired coupling traces (PCTs) located between the PSN and NSN traces that serve as both power transformers for the system and as an aid to impedance matching between the RF input port (RIP) and RF output ports (ROPs). The system is electrically symmetric and provides for power splitting and/or combining functionality between the RIP and ROPs.
