Embodiment Construction

[0031] FIG. 1 shows a receiver 5 of the invention comprising an antenna stage 4 , a first frequency conversion stage 1 , a second frequency conversion stage 2 and a processing stage 3 . The antenna stage 4 comprises an antenna connected to a low noise amplifier 42 via an antenna filter 41 . The first frequency conversion stage 1 comprises a first mixer 11 and a further first mixer 12 , the first inputs of which are connected to the output of a low noise amplifier 42 . The second inputs of the first mixer 11 and of the further first mixer 12 are connected to the output of the first oscillator 19 . The first oscillator 19 provides an in-phase first oscillating signal to the first mixer 11 , and the first oscillator 19 provides a quadrature first oscillating signal to another first mixer 12 . Therefore, the first mixer 11 generates an in-phase first intermediate frequency signal, and another first mixer 12 generates a quadrature first intermediate frequency signal.

Abstract

Receivers (5) for simultaneously receiving different radio frequency signals according to different standards are provided with first frequency translating stages (1) for converting the radio frequency signals into first intermediate frequency signals and second frequency translating stages (2) for converting the first intermediate frequency signals into second intermediate frequency signals and processing stages (3) for retrieving first information from the first intermediate frequency signals and second information from the second intermediate signals. As a result, such receivers (5) have relatively low power consumption. The first frequency translating stages (1) comprise first oscillators (19) and first mixers (11) and further first mixers (12). The second frequency translating stages (2) comprise second oscillators (29) and second mixers (21) and further second mixers (22) and third mixers (23) and further third mixers (24). The processing stages (3) comprise filters (31) for filtering the first intermediate frequency signals for removing the second information and further filters (32) for filtering the second intermediate frequency signals for removing the first information.

Description

field of invention [0001] The invention relates to a receiver for simultaneously receiving a first radio frequency signal and a second radio frequency signal, the first radio frequency signal according to a first standard, the second radio frequency signal according to a second standard, the second standard being different from the first standard, and the invention also relates to frequency Conversion circuit, method thereof and processor program product. Background technique [0002] Such receivers are, for example, wireless receivers, wireless transceivers and wireless interfaces. [0003] WO 01 / 035578 A1 discloses a transceiver comprising a first upconverting / downconverting pair and a second upconverting / downconverting pair. In the transceiver, the down-conversion parts of the two up-conversion / down-conversion pairs form the receiver, and the up-conversion parts of the two up-conversion / down-conversion pairs form the transmitter. These up-conversion / down-conversion pair...
