Empfänger und Verfahren zum Empfangen eines ersten Nutzfrequenzbandes und eines zweiten Nutzfrequenzbandes

DE 102006029482 A1 UPAB: 20080118 NOVELTY - The receiver (100) has a band-pass filter device (110) filtering a receiving signal (112), and a mixing device (120) transferring combination signals or band pass filter signals with a local oscillator signal (122). A frequency synthesizer produces the oscillator signal. An intermediate frequency filter device (130) filters intermediate frequency signals to receive filtered intermediate frequency signals. An analog-to-digital-converter device (140) converts the filtered analog intermediate frequency signals using an individual sampling rate to receive digitized intermediate frequency signals. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method of receiving of utilizable frequency bands. USE - Broadband low-intermediate frequency-dual-receiver e.g. high-precision such as dual receiver, global positioning system (GPS)-dual receiver, Galileo-dual-receiver, Glonass-dual receiver and global navigation satellite system (GNSS)-dual receiver, and single band-receiver, for receiving utilizable frequency bands in a field of a communication technology, for satellite-supported positioning, a position determining system and a navigation system e.g. GPS-satellite navigation system and Galileo-satellite navigation system. ADVANTAGE - The intermediate frequency filter device filters the intermediate frequency signals that are generated by the mixing device in an efficient manner. The receiver is designed in such a manner that only one frequency synthesizer is required to produce the local oscillator signals, thus enabling simultaneous receiving of the two utilizable frequency bands to save resources regarding switching cost and power consumption, and hence reducing the cost of resources
