摘要： A direct conversion satellite tuner is fully integrated on a common substrate. The integrated tuner receives an RF signal having a plurality of channels and down-converts a selected channel directly to baseband for further processing. The integrated tuner includes on-chip local oscillator generation, tunable baseband filters, and DC Offset cancellation. The integrated tuner can be implemented in a completely differential I/Q configuration for improved electrical performance. The entire direct conversion satellite tuner can be fabricated on a single semiconductor substrate using standard CMOS processing, with minimal off-chip components. The tuner configuration described herein is not limited to processing TV signals, and can be utilized to down-convert other RF signals to an IF frequency or baseband.

摘要： A communication system for communicating CDMA and GSM transmit and receive RF information signals through one or more antennas is disclosed. The communication system is comprised of a transmitting unit, a receiving unit, and at least one antenna. The transmitting unit modulates and upconverts a transmit baseband information signal to generate a CDMA transmit RF information signal and a GSM transmit RF information signal. The receiving unit downconverts and demodulates a CDMA receive RF information signal and a GSM receive RF information signal to generate a receive baseband information signal. One or more antennas are coupled to the transmitting unit and receiving unit for transmitting the CDMA transmit RF information signal and the GSM transmit RF information signal, and receiving the CDMA receive RF information signal and the GSM receive RF information signal. The transmitting unit comprises a modulator for modulating a transmit IF LO frequency with the transmit baseband information signal to generate a transmit IF information signal. It also includes a plurality of upconverters for upconverting the transmit IF information signal with a GSM transmit RF LO frequency to generate a GSM transmit RF information signal, and for upconverting the transmit IF information signal with a CDMA transmit RF LO frequency to generate at least one CDMA transmit RF information signal. The receiving unit comprises a downconverter for downconverting a CDMA receive RF information signal with a receive RF LO frequency to generate a receive IF information signal, and for downconverting at least one GSM receive RF information signal with the receive RF LO frequency to generate a receive IF information signal.

摘要： A modulated signal is translated to a broadcast frequency by a translation phase lock loop. In the translation phase lock loop the output frequency, which is the broadcast frequency, is mixed with a translation frequency, and the resulting translated frequency is compared to the modulated signal. If an amplitude modulator is inserted into the translation loop, the phase comparison/feedback nature of the phase lock loop will tend to cancel the phase noise introduced in the amplitude modulation process. Any other circuits placed within the loop will tend to have any phase noise they introduce, which is in the phase lock loop bandwidth, canceled by the loop.

摘要： The present invention includes a Voltage Controlled Oscillator (VCO) having a resonant circuit capable of being quickly switched between two resonant frequencies in order to generate two different LO frequencies. In a preferred embodiment, the present invention includes a VCO having a dual-frequency resonant circuit attached to the VCO's resonant circuit input leads. The dual-frequency resonant circuit is constructed in a differential architecture in order to create a number "virtual ground" points within the circuit that nearly eliminate any ground currents, and thus minimize the time required to switch the resonant circuit between the two LO frequencies. The switching between two resonant frequencies is achieved by creating a short circuit across certain components within the circuit to eliminate them from the resonant circuit. The combination of the differential architecture dual-frequency resonant circuit with a single VCO provides for the power efficient and space-saving generation of both LO frequencies needed for a wireless transceiver. Moreover, by requiring only one resonant circuit, the area on the circuit board within the wireless transceiver is greatly reduced, resulting in a smaller transceiver circuit.
