摘要： A tunable multi-band receiver supporting operation on a plurality of frequency bands is disclosed. In an exemplary design, the tunable multi-band receiver includes an antenna tuning network, a tunable notch filter, and at least one low noise amplifier (LNA). The antenna tuning network tunes an antenna (e.g., a diversity antenna) to a receive band in a plurality of receive bands. The tunable notch filter is tunable to a transmit band in a plurality of transmit bands and attenuates signal components in the transmit band. One LNA among the at least one LNA amplifies an output signal from the tunable notch filter. The tunable multi-band receiver may further include one or more additional tunable notch filters to further attenuate the signal components in the transmit band.

摘要： A circuit receives a first signal (for example, a baseband signal) and mixes it with a local oscillator (LO) signal, and outputs a second signal (for example, an RFOUT signal). The circuit includes multiple identical Mixer and Frequency Divider Pair (MFDP) circuits. Each MFDP can be enabled separately. Each MFDP includes a mixer and a frequency divider that provides the mixer with a local version of the LO signal. The MFDP outputs are coupled together so that the output power of the second signal (RFOUT) is the combined output powers of the various MFDPs. By controlling the number of enabled MFDPs, the output power of the second signal is controlled. Because the MFDPs all have identical layouts, accuracy of output power step size is improved. Because LO signal power within the circuit automatically changes in proportion to the number of enabled MFDPs, local oscillator leakage problems are avoided.

摘要： A bi-polar modulator that can perform quadrature modulation using amplitude modulators is described. In one design, the bi-polar modulator includes first and second amplitude modulators and a summer. The first amplitude modulator amplitude modulates a first carrier signal with a first input signal and provides a first amplitude modulated signal. The second amplitude modulator amplitude modulates a second carrier signal with a second input signal and provides a second amplitude modulated signal. The summer sums the first and second amplitude modulated signals and provides a quadrature modulated signal that is both amplitude and phase modulated. The first and second input signals may be obtained based on absolute values of first and second modulating signals, respectively. The first and second carrier signals have phases determined based on the sign of the first and second modulating signals, respectively. Each amplitude modulator may be implemented with a class-E amplifier.

摘要： A low-cost diversity receiver includes two receiver units for a primary path and a secondary/diversity path. The first receiver unit is compliant with, for example, IS-98D requirements. The second receiver unit is not fully compliant with the IS-98D requirements (e.g., may meet requirements for sensitivity but not for out-of-band rejection). The second receiver unit is wideband and designed with lower power consumption, less area, and lower cost than the first receiver unit. For a multi-antenna receiver, the two receiver units are used to simultaneously process two received signals from two antennas. For a single-antenna receiver, one of the two receiver units is used to process a received signal from one antenna. For a dual-band design, each receiver unit can operate at two frequency bands. Narrowband circuit blocks are used for the first receiver unit, and wideband circuit blocks are used for the second receiver unit.
