    摘要: Devices (1) for exchanging ultra wide band signals comprise frequency translating stages (20,30) for frequency translating signals and oscillating stages (40) for supplying main inphase/quadrature oscillation signals to the frequency translating stages (20,30). By providing the oscillating stages (40) with polyphase filters (43,44) for reducing harmonics in oscillation signals, the main oscillation signals will be sufficiently clean. The oscillating stages (40) comprise mixers (46) for converting first inphase/quadrature oscillation signals and second inphase/quadrature oscillation signals into the main oscillation signals. The polyphase filters (43,44) may be located before and after the mixers (46). Frequency selectors (45) replace prior art multiplexers located after the mixers (46). Such frequency selectors (45) comprise multiplexers (126,127) for supplying the second inphase/quadrature oscillation signals, with a combination of these second oscillation signals corresponding with a positive frequency, a negative frequency or a zero frequency, and comprise coders (125) for controlling the multiplexers (126,127).

    摘要: An oscillation signal with a selectable frequency is generated with a phase locked loop (10, 12, 14). The oscillator (10) of the loop receives a feedback signal, to which an offset is added in order to reduce transient effects when a frequency modification is made. A first and second offset control value are used to control the offset successively. The first offset control value is controlled by a combination of the frequency settings before and after the modification. The second offset control value is controlled by the frequency settings after the modification. The first and second offset control values are used to control an offset of applying to a frequency control signal of an oscillator (10) of the phase locked loop (10, 12, 14). The offset controlled by the first control offset value is applied during a predetermined time interval before the offset controlled by the second control offset value is applied.

    摘要: The invention relates to an antenna diversity comprising a first and a second antenna element one of which is operated in an active mode whereas the other one of which is operated in a parasitic mode. It is the object of the present invention to further minimize the amount of mismatch by still being able to maximize a predetermined signal quality criterion for the electromagnetic signal on the active path between the active antenna and the transceiver. This object is solved by a switching unit 120 for either operating the first antenna element in the parasitic mode and simultaneously operating the second antenna element in the active mode or vice versa and by providing a pre-selection unit 130 as well as a selection unit 140 for selecting an optimal configuration for the antenna diversity ensuring that the amount of said mismatch is below a predetermined threshold value and that simultaneously a predetermined quality criterion for the transceived electromagnetic signal is fulfilled best. The antenna diversity further comprises a control unit 150 for adjusting said selected configuration. The invention further relates to a method for operating such an antenna diversity.
