  • Patent number: 6614837
    Abstract: A low noise transmitting device is disclosed. The transmitting device receives a modulated signal having a modulation bandwidth and an intermediate center frequency and generates a modulated transmit band signal at a carrier frequency. The transmitting device includes a first filter that receives the modulated signal and passes frequencies within the modulation bandwidth, producing a low noise filtered modulated signal, and a low noise frequency source that generates a low noise main synthesizer frequency. The filtered modulated signal and the main synthesizer frequency are then fed into a mixer that mixes the two signals (produces either the sum or difference). The output is a low noise modulated transmit band signal that may be amplified to transmit power levels without the need for power-inefficient post-amplification filtering.

  • Patent number: 6415001
    Abstract: A communication system for communicating RF signals at any one of a plurality of communication standards through a common antenna is disclosed. The communication system comprises a transmitting unit, a receiving unit, an IF LO frequency generator, an RF LO frequency generator, a reference source, and an antenna. The transmitting unit has a transmit RF information signal output, a modulator for transforming a transmit baseband information signal into a modulated transmit IF information signal, and an upconverter for upconverting the transmit IF information signal into a transmit RF information signal.
