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： Techniques for operating a receiver to achieve good linearity performance and higher receive signal to noise ratio are described. The receiver includes one or more circuit blocks, e.g., a low noise amplifier (LNA), having discrete gain states. The gain states are selected based on switch points, with each switch point indicating a specific received signal level at which to switch from one gain state to another gain state. The switch points may be dynamically selected based on channel conditions, which may be characterized by the presence or absence or strength or frequency of jammers. A first set of switch points may be selected when jammers are detected, and a second set of switch points may be selected when jammers are not detected. The gain states are selected in accordance with the set of switch points selected for use.

摘要： Techniques for operating two receivers to receive data and paging from two systems are described. A primary receiver is associated with better performance than a secondary receiver under poor RF conditions. The two receivers may be operated in either a hybrid mode in which the primary receiver is used to receive paging or a simultaneous mode in which the second receiver is used to receive paging. One of the modes may be selected for use based on RF conditions, received power, demodulation metrics, and/or other criteria. In one design, a mode is selected based on the received power and one or more thresholds. In another design, the hybrid mode is selected for poor RF conditions and, for good RF conditions, the hybrid or simultaneous mode is selected based on received power.

摘要： A low-power diversity receiver includes at least two receive paths, each of which is designated as a primary or secondary receive path. A primary receive path is compliant with system requirements (e.g., IS-98D requirements). A secondary receive path is not fully compliant with the system requirements and is designed for lower power, less area, and lower cost than the primary receive path. For a multi-antenna receiver, the two receive paths may be used to simultaneously process two received signals from two antennas. For a single-antenna receiver, either the primary or secondary receive path is selected, e.g., depending on whether or not large amplitude "jammers" are detected, to process a single input signal from one antenna. The receiver may include additional receive paths for additional frequency bands and/or GPS.

摘要： An integrated circuit for achieving power reduction in a transceiver may include a jammer detector that determines an interference level corresponding to a received signal, and a transmit power detector that determines a required transmit power level for a transmitted signal. The integrated circuit may also include at least one of the following: a process monitor that determines process corners of components within the receiver and/or the transmitter, and a temperature monitor that determines a temperature of the receiver and/or the transmitter. The integrated circuit may also include a state machine. The state machine may transition the receiver from a high linearity mode to a low linearity mode if a set of operating conditions is satisfied. Similarly, the state machine may transition the transmitter from a high power mode to a low power mode if a set of operating conditions is satisfied.

摘要： Within a receiver, the frequency of a comparison reference clock signal supplied to a fractional-N Phase-Locked Loop (PLL) is dynamically changed such that undesirable reciprocal mixing of reference spurs with known jammers (for example, transmit leakage) is minimized. As the transmit channel changes within a band, and as the transmit leakage frequency changes, a circuit changes the frequency of the comparison reference clock signal such that reference spurs generated by the PLL are moved in frequency so that they do not reciprocally mix with transmitter leakage in undesirable ways. In a second aspect, the PLL is operable either as an integer-N PLL or a fractional-N PLL. In low total receive power situations, the PLL operates as an integer-N PLL to reduce receiver susceptibility to fractional-N spurs. In a third aspect, jammer detect information is used to determine the comparison reference clock signal frequency.
摘要翻译：在接收机内，提供给分数N锁相环（PLL）的比较参考时钟信号的频率被动态地改变，使得具有已知干扰的参考杂波（例如，传输泄漏）的不期望的相互混合被最小化。当发射信道在频带内变化时，并且随着发射泄漏频率的变化，电路改变比较参考时钟信号的频率，使得PLL产生的参考杂波频率移动，使得它们不与发射机泄漏相互混合以不良的方式。在第二方面，PLL可以作为整数N个PLL或分数N PLL来操作。在低总接收功率情况下，PLL作为整数N PLL进行操作，以减少接收机对分数N个杂散的敏感性。在第三方面，使用干扰检测信息来确定比较参考时钟信号频率。
