摘要： A down-converter for receiving a multiband radio frequency signal (RF) and a local oscillator signal comprises a frequency divider and a heterodyne receive chain. The frequency divider is configured to divide the local oscillator signal and provide different divided local oscillator signals. The heterodyne receive chain comprises a first stage mixer and second stage mixers. The first stage mixer is configured to mix the multiband radio frequency signal and either the local oscillator signal or a divided local oscillator signal to generate a first intermediate frequency signal. Each second stage mixer is configured to mix the first intermediate signal and a divided local oscillator signal to generate second intermediate frequency signals that each represent a band from the multiband radio frequency signal. The frequency divider is configured to provide a different divided local oscillator signal to each of the second stage mixers.

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： A frequency-hopping arrangement comprises a basic-frequency branch (DIV1), an offset-frequency branch (DIV2, DIV3, SCC), and a controllable frequency converter (SBM, FSC). The basic-frequency branch (DIV1) receives an oscillator signal (OS) having an oscillator-signal frequency (7920 MHz). The basic-frequency branch has a frequency-division factor (/2) so as to provide a basic-frequency signal (BF) having a basic frequency (+3960 MHz) that is the oscillator-signal frequency divided by the frequency-division factor. The offset-frequency branch (DIV2, DIV3, SCC) receives the same oscillator signal (OS). The offset-frequency branch has a different frequency-division factor (/3, /5) so as to provide an offset-frequency signal (OF) having an offset frequency (+528 MHz) that is the oscillator-signal frequency divided by the different frequency-division factor. The controllable frequency converter (SBM, FSC) provides a frequency-hopping signal (FHS) having a frequency (cl*+3960+c2*+528 MHz) that is a linear combination of the basic frequency and the offset frequency with at least one coefficient (c2) that varies as a function of a hopping-control signal (HCS).

摘要： The present invention relates to a polar modulation apparatus and method, in which an in-phase and a quadrature-phase signal are processed in the analog domain to generate an analog signal corresponding to a derivative of a phase component of said polar-modulated signal. The analog signal is then input to a control input of a controlled oscillator (40). As an example, the processing may be based on a differentiate-and-multiply algorithm in the analog domain. Thereby, phase and envelope signals are generated in the analog domain and bandwidth enlargement due to the processing of the polar signals and corresponding aliasing can be prevented to obtain a highly accurate polar-modulated output signal.
