Abstract: A protection module (4) for a RF-amplifier (2) is efficient against overvoltage due to load impedance mismatch when said RF-amplifier is connected to a load RF-element (3). The protection module comprises a branch with at least one diode-like operating component (D1, D2, . . . , Dn) and a resistor (R2) which starts conducting when a RF-signal on a transmission link (6) between the RF-amplifier and the load RF-element is higher than a threshold set by the diode-like operating component. Such protection may be implemented in MOS technology only.

Abstract: A downlink signaling counter management method is disclosed for a communication device adapted to be simultaneously associated with at least two subscriber identities and adapted to simultaneously provide radio receiving capabilities to less than all of the at least two subscriber identities. The method comprises, for each decoding of a paging block for a subscriber identity, determining whether the paging block decoding was correct and determining whether a previous paging block decoding condition is fulfilled. If the paging block decoding is correct, the downlink signaling counter is updated with a first value if the previous paging block decoding condition is fulfilled and with a second value if the previous paging block decoding condition is not fulfilled. If the paging block decoding is not correct and if the paging block decoding was based on a maximum number of paging bursts, the downlink signaling counter is updated with a third value if the previous paging block decoding condition is fulfilled and with a fourth value if the previous paging block decoding condition is not fulfilled. Corresponding computer program product, system and device are also disclosed.

Abstract: A two-stage, passive, RC polyphase filter for mm-wave quadrature LO generation is presented. The filter features an innovative, symmetrical layout structure, which is more robust to parasitics than the conventional layout. Layout parasitics which become important at mm-wave frequencies are identified and a compensated. Impedance variations and transfer functions are evaluated considering these dominant parasitics. More than 15 dB improvement in image rejection ratio is achieved in comparison with conventional layouts. Using the inventive techniques more than 35 dB of image rejection ratio over a bandwidth of 6 GHz is demonstrated in an outphasing transmitter at 60 GHz in 40 nm CMOS.

Abstract: Time frames (TFs) are allocated for performance of transactions of a low latency data stream (LLDS) and a best effort data stream (BEDS) in Bluetooth®-like equipment, wherein payload carrying packets of the different data streams are equal in size, each occupying multiple TFs. An overrule mechanism enables uncompleted transactions of one data stream to continue as needed into TFs allocated to another data stream. Every TF within an allocation window (AW) is individually allocated to the LLDS or the BEDS, and plural TFs immediately following the AW form a guard space between adjacent AWs, the guard space being allocated to neither the LLDDS or the BEDS. Configuration of the AW and of the guard space guarantees the LLDS a first opportunity to transmit a payload carrying packet and continued opportunities to retransmit the packet until successful, after which the BEDS is given an opportunity for transmission and possible retransmissions.

Abstract: A voltage regulator includes a current bridge and first and second current paths coupling a current mirror to respective first and second voltage-to-current converters. The current mirror controls a second current dependent on a first current. The first voltage-to-current converter controls the first current dependent on either a reference voltage or a feedback voltage derived from the regulator's output voltage, and the second voltage-to-current converter controls the second current dependent on the other of the feedback and reference voltages. Voltage-to-current conversion by the first converter is independent of voltage-to-current conversion by the second converter. An output transistor stage coupled to the second current path controls the output voltage dependent on the voltage in the second current path indicative of a deviation of the second current from a target current value dependent on the reference voltage.
