摘要： The present invention relates to a transceiver, receiver module, computer program product and method for compensating a group delay variation in a transceiver, wherein an oscillator frequency used for transmitting a calibration signal is varied, and the calibration signal is transmitted via a transmission antenna (25) of the transceiver circuit and directly received via a receiving antenna (24) of the transceiver circuit. A DC component in 5 the received calibration signal is detected and stored in association with said transmission frequency, and a frequency dependent delay generated in the transceiver is compensated based on the stored DC component.

摘要： At microwave frequencies, the use of transmission lines as a design element becomes interesting due to the small wavelengths. Inductors as part of an on-chip resonator can be made with a shorted stub, which is a transmission line, shorted at the end. Placing a MIM-capacitor (40) at the beginning of the shorted stub can make a resonator (100). Shielding this kind of resonator by means of vias (20) or stacked vias enables very compact filter designs.

摘要： An integrated variable capacitance with low losses comprises an array (1) of switched capacitors (2-8). When using an array (1) of switched capacitors (2-8) to form a quasi continuously variable capacitor, a continuity of capacitance as function of the digital control signal to the array (1) leads to overall behavior of the series resistance of the array (1) as function of the capacitance that for some applications may be undesirable. Therefore a topology for a switched array (1) is proposed that allows to set series resistance relatively independent from capacitance. The array (1) may be fully or partially integrated in tunable LC filters, also in TV tuners.

摘要： The invention relates to an integrated tuner circuit, preferably to a TV-tuner circuit using double conversion. It is a major purpose of the invention to modify a prior art tuner circuit in a way such that a high degree of integration is achieved. This is contrary to the state of the art in which tuners comprise many discrete components and comprise a lot of adjusting and alignment points. A high degree of integration will substantially reduce the costs, not only production costs but also costs accompanying the complex adjusting procedure. Also, by increasing the degree of integration dimensions may be substantially reduced. In view of the above purpose the invention provides an integrated tuner circuit having a first polyphase filter (10) at the input side of a fully complex mixer (13), and a second polyphase filter (15) at the output of the fully complex mixer (13).

摘要： A signal processing arrangement (REC) comprises a filter (PPF) with variable filter elements (FE). A switching circuit (SWCT) switches a filter element (FE1) and, subsequently, another filter element (FE3) from a filter state to an adjustment state and back again to the filter state. A filter element that is in the filter state contributes to a suppression of unwanted signals. A filter element that is in the adjustment state affects a characteristic of a measurement signal (Sm). An adjustment circuit (ADCT) adjusts the filter element that is in the adjustment state so that the characteristic of the measurement signal is substantially equal to a target value (TV).
