摘要： A balanced oscillator comprises a frequency selective circuit and a balanced active circuit coupled with the frequency selective circuit. The frequency selective circuit includes a short circuited quarter-wave paired line. A cost effective short circuited quarter-wave paired line can be U-shaped to take up only a small space and can be integrated easily on a dielectric, especially glass. The balanced active circuit comprises a cross coupled differential pair of transistors. The balanced oscillator can be tuned in a number of different ways.

摘要： A radio transmission system is disclosed for operating in a multipath transmission environment having improved reception, and in the case of bi-directional systems, also improved transmission. This is achieved by using at least two reception beams, corresponding to one fixed reception beam and one scanning reception beam, and by continuously evaluating the quality of these beams as to their signal-to-noise-and-interference ratios or bit-error-rates (BERs). The best beam is dynamically chosen to be the fixed beam. Alternatively, the fixed beam is updated with the best beam acquired by the scanning beam as compared to the current fixed beam. In a bi-directional system, the receiving radio apparatus applies the direction of the best reception beam for transmission to the opposite radio apparatus.

摘要： A radio transmission system comprises a phased-array radio apparatus for optimizing reception in a multipath transmission environment. In the phased-array radio apparatus, phase shifting is performed after down-conversion of received RF signals. Phase control and beam-forming are simple. By applying a zero-IF or low-IF receiver structure, the complete structure can easily be fully integrated.

摘要： A transceiver comprises transmitter means and receiver means, mode means coupled to the transmitter means and the receiver means for simultaneously performing a receiving and transmitting of signals, oscillator means coupled to each of the transmitter means and the receiver means respectively, and frequency divider means coupled between the oscillator means on the one hand and the transmitter means, and receiver means respectively on the other hand. Such a transceiver is capable of operating in full duplex mode without the necessity to adding extra oscillator means to achieve such an operational mode, while in addition this saves components, costs, chip area, power dissipation and weight, which is important for in particular mobile communication applications.
