  • High-dynamic-range ultra wide band transceiver
    Patent number: 7567786
    Abstract: An UWB Transceiver for Multi-Band OFDM communication including an antenna switch (342), a receive front end and down-converter (303), an up-converter and power amplifier (305), and a frequency synthesizer (211). The transceiver achieves high dynamic range by employing a synthesizer (211) with very low spurious components and a receive front end with an efficient receive RF filtering embodiment. The synthesizer (211) may rapidly switch frequencies in a manner that minimizes spurious components outside the band group used for communication. The receiver (200) also achieves high selectivity and sensitivity by dividing the receive signal path into even and odd band groups.
