摘要： The present invention relates to a multiple band receiver comprised in a mobile terminal. The receiver is able to receive radio signals in an upper frequency band (FBU) and a lower frequency band (FBL). The multiple band receiver comprises an antenna (ANT), a converting receiver part (R1), a heterodyne receiver part (R2) and a voltage controlled oscillator (VCO). The voltage controlled oscillator generates local oscillator frequencies (fLO) substantially equal to the frequency shift between the two frequency bands. Radio signals (fRF) in the upper frequency band (FBU) are converted in the converting receiver part (R1) to substantially lower frequency band (FBL) by mixing with a local oscillator frequency (fLO). The converted signal is mixed in the heterodyne receiver part (R2) with the same local oscillator frequency (fLO) thus generating the same first intermediate frequency (fIF1) as for signals in the upper frequency band.

摘要： A receiver for receiving reception signals of a first type, for example TV signals, and reception signals of a second type, for example FM-radio signals, is described. The receiver may be used in multimedia applications. In the receiver, a single tuner TUN frequency converts a reception signal RFS into an intermediate frequency signal IFS. For relatively small-size implementations, the following is proposed. The receiver is a single conversion receiver for both types of reception signals, the single conversion being effected in the tuner TUN. Depending on whether a first-type or second-type reception signal is desired, the tuner TUN provides the intermediate frequency signal IFS at a first intermediate frequency IF1 or a second intermediate frequency IF2, respectively. The intermediate frequency signal IFS at intermediate frequency IF1 is processed in a first intermediate frequency signal processor IFSP1. Alternatively, the intermediate frequency signal IFS at the second intermediate frequency IF2 is processed in a second intermediate frequency signal processor IFSP2.

摘要： Biomedical implants in accordance with various embodiments of the invention can be implemented in many different ways. The implants can be configured to receive power and transmit data, both wirelessly and simultaneously. Such devices can be configured to receive power from an external source and transmit data, such as but not limited to recorded neural data and/or other biological data, to outside the body. In many cases, the data is transmitted to the device that delivers power to the implant. For example, the power and data transmission system can be implemented with a pair of transceivers. The implant transceiver can receive power wirelessly though an external transceiver while simultaneously transmitting data to the external transceiver. In several embodiments, both forward (power) and reverse (data) links use the same pair of inductive coils in the transceivers, one coil mounted in the implant and the other in the external unit.

摘要： A MEMS tunable capacitor comprises first and second opposing capacitor electrodes (10,12), wherein the second capacitor electrode (12) is movable by a MEMS switch to vary the capacitor dielectric spacing, and thereby tune the capacitance. A tunable dielectric material (14) and a non- tunable dielectric material are in series between the first and second electrodes. The tunable dielectric material occupies a dimension gd of the electrode spacing, and the non-tunable dielectric material occupies a dimension g of the electrode spacing. A third electrode (20) faces the movable second electrode (12) for electrically controlling tunable dielectric material. A controller is adapted to vary the capacitor dielectric spacing for a first continuous range of adjustment of the capacitance of the MEMS capacitor, and to tune the dielectric material (14) for a second continuous range of adjustment of the capacitance of the MEMS capacitor, thereby to provide a continuous analogue range of adjustment including the first and second ranges. This arrangement provides independent control of the MEMS function and the dielectric tuning function, and enables a continuous adjustability.

摘要： The invention relates to a high frequency input stage comprising a high frequency coupling element (KE), which couples an air interface (ANT) to the inputs of high frequency resonant circuits (HR1, HR2) that are connected in parallel. In order to realize a switchless circuit with a simple design, only one capacitor (C3) that forms a low pass filter is provided in the coupling element (KE), which divides an antenna signal up on the different bands thereby suppressing influences of a band that is other than the selected band. The high frequency input stage can be used, for example, in three-band TV tuners.
