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.
摘要翻译：描述了用于操作接收机以获得良好线性性能和较高接收信噪比的技术。接收机包括一个或多个具有离散增益状态的电路块，例如低噪声放大器（LNA）。根据切换点选择增益状态，每个切换点表示从一个增益状态切换到另一增益状态的特定接收信号电平。可以基于信道条件动态地选择切换点，其可以由干扰的存在或不存在或强度或频率来表征。当检测到干扰时，可以选择第一组切换点，并且当没有检测到干扰时可以选择第二组切换点。增益状态根据所选择的切换点集合进行选择。

摘要： Techniques for controlling operation of control loops in a receiver are described. The operation of at least one control loop is modified in conjunction with a change in operating state, which may correspond to a change in linearity state, gain state, operating frequency, antenna configuration, etc. A change in linearity state may occur when jammers are detected and may cause bias current of analog circuit blocks to be adjusted. The at least one control loop to be modified may include a DC loop, an AGC loop, etc. The operation of a control loop may be modified by disabling the control loop or changing its time constant prior to changing operating state, waiting a predetermined amount of time to allow the receiver to settle, and enabling the control loop or restoring its time constant after waiting the predetermined amount of time.
摘要翻译：描述了用于控制接收机中的控制环路的操作的技术。结合操作状态的改变来修改至少一个控制回路的操作，其可以对应于线性状态，增益状态，操作频率，天线配置等的改变。线性状态的变化可能发生在干扰器并且可能导致模拟电路块的偏置电流被调整。要修改的至少一个控制环路可以包括DC环路，AGC环路等。可以通过在改变操作状态之前禁用控制环路或改变其时间常数来修改控制环路的操作，等待预定量的时间以允许接收机安定，并且在等待预定时间量之后启用控制环路或恢复其时间常数。

摘要： Although the duplexer in a full-duplex transceiver circuit may only be guaranteed by the duplexer manufacturer to have a transmit band rejection from its TX port to its RX port of a certain amount, and may only be guaranteed to have a receive band rejection of another amount, the actual transmit band rejection and the actual receive band rejection of a particular instance of the duplexer may be better than specified. Rather than consuming excess power in the receiver and/or transmitter in order to meet performance requirements assuming the duplexer only performs as well as specified, the duplexer's in-circuit performance is measured as part of a transmitter-to-receiver isolation determination. Transmitter and/or receiver power settings are reduced where possible to take advantage of the measured better-than-specified in-circuit duplexer performance, while still meeting transceiver performance requirements. Power settings are not changed during normal transmit and receive mode operation.
摘要翻译：虽然全双工收发器电路中的双工器可能只能由双工器制造商保证从其TX端口到其一定数量的RX端口的发射波段抑制，并且只能保证具有另一个的接收频带抑制数量，双工器的特定实例的实际发射频带抑制和实际接收频带抑制可能优于指定的。假设双工器仅执行指定，而不是在接收机和/或发射机中消耗多余的功率，以满足性能要求，则双工器的在线性能是作为发射机到接收机隔离确定的一部分进行测量的。发射机和/或接收机功率设置在可能的情况下可以减少，以便在仍然满足收发器性能要求的同时利用测得的优于指定的在线双工器性能。在正常的发送和接收模式操作期间，电源设置不会改变。

摘要： System(s) and method(s) are provided for dynamically scaling switching frequencies and clock sources of switched mode power supplies (SMPSs) in a mobile station. Switching frequency is scaled to an optimal value in response to at least one of (i) a change in mode of operation for wireless communication employed by the mobile station, an additional mode of operation is triggered, (ii) a change in operation conditions of a set of loads associated with functionality of the mobile is determined, or (iii) an LO spur set-off by a SMPS in the presence of an interference signal with a frequency splitting from an operational band that matches the SMPS frequency or at least one of its harmonics. Switching frequencies can be selected from a lookup table, or through an analysis of switching frequencies available to the mobile and operational criteria. A set of clock sources can provide an ensemble of switching frequencies.
