Abstract: An up conversion mixer has a Gilbert cell arrangement including an input amplification part (BB) for producing an amplified signal coupled to a multiplication part (RF), the multiplication part being arranged to multiply the amplified signal by a local oscillator signal (LO) and output a mixed signal, the mixer also having a capacitor (90,100,15) coupled from a node between the input amplification part and the multiplication part, to a power supply line, for suppressing unwanted high frequency signal components of the output signal of the multiplication part. The linearity of such mixers can be improved considerably by this impedance on the source node of the switch transistors. This capacitance can be placed to either VSS or to VDD. Notably this improvement can be achieved with low power consumption since no additional power is needed for the increased performance.

Abstract: A radio transmission method and a radio transmitter device for radio transmission of an audio signal from an audio device to a radio receiver is described, wherein an audio signal is received from the audio device; and an RF signal is transmitted simultaneously which is modulated with the audio signal on each of a set of at least two different RF channels. Within each of the transmitted RF signals, information identifying at least the other RF channels in the set of RF channels is included.

Abstract: Methods and devices for the compensation for variations in the frequency drift of a free-running VCO/DCO (voltage/digital controlled oscillator), e.g. inside a frequency synthesizer, are described. In one aspect, the frequency drift of the high-frequency synthesizer is compensated by adjusting the frequency of the baseband signal.
A counter unit is used to determine the frequency offset between the frequency of the free-running oscillator and a reference clock. A difference signal is used to correct the upstream or downstream signal.

Abstract: An RF transmitter suitable for ISM band transmissions has an IF modulator (120) and an RF modulator (150), the IF modulator being arranged to use a very-low-IF-frequency f IF , smaller than half the channel bandwidth, such that spurious unwanted modulation components fall in other channels having a channel number within one or two of a channel being transmitted. This can reduce the VCO pulling problem and reduce adjacent channel power degradation compared to using higher IF frequencies. The local oscillator PLL's fractionality is used in order to optimize the adjacent power frequency plan by selecting the most appropriate IF frequency. For the "Bluetooth ® Wireless Technology" application, the IF frequency is

Abstract: A low noise differential amplifier has a pair of single ended common-gate or common-base circuits and cross coupling of an input of one of the pair to the gate or base of the other one of the pair. This cross-coupling puts the differential input voltage over the Gate-Source of the common-gate transistor (or Base-Emitter of the common base transistor). This means that the same input impedance and gain can be made with half the current compared to a basic common-gate topology. The cross-coupling means the noise generated by the positive side of the common-gate structure ends up partly on the negative output and vice versa, and so the Noise Figure can be less than 3dB.
