摘要： Techniques for generating local oscillator (LO) signals are described. In one design, an apparatus may include a deskew circuit and a divider circuit. The deskew circuit may receive a differential input oscillator signal having timing skew and provide a differential output oscillator signal having reduced timing skew. The differential input oscillator signal may include first and second input oscillator signals, and the differential output oscillator signal may include first and second output oscillator signals. In one design, the deskew circuit may include first and second variable delay circuits that receive the first and second input oscillator signals, respectively, and provide the first and second output oscillator signals, respectively. Each output oscillator signal may have an adjustable delay selected to reduce timing skew. The divider circuit may divide the differential output oscillator signal in frequency and provide differential I and Q divided signals, which may be used to generate LO signals.

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： 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： This disclosure describes techniques for reducing adverse effects of TX signal leakage in a full-duplex, wireless communication device. The techniques make use of a notch filter to reject TX signal leakage in a signal processed in the RX path of the wireless communication device. The notch filter may be constructed as a complex notch filter using passive resistor and capacitor components to produce a notch frequency that attenuates TX signal leakage components in a desired signal. The notch filter may be applied to a down-converted, baseband signal produced by a passive mixer.

摘要： An apparatus, which may be configured as a receiver or transceiver, includes a plurality of super regenerative (SR) amplifiers coupled in parallel, wherein the SR amplifiers are tuned to distinct frequency bands, respectively. The apparatus may further include isolation amplifiers at the respective inputs and outputs of the SR amplifiers to prevent injection locking and reduce power leakage. The apparatus may include a circuit to reduce or substantially eliminate in-band jamming signals. The apparatus may form at least part of a wireless communications device adapted to receive signals from other wireless communications devices, adapted to transmit signal to other wireless communications devices, and adapted to both transmit and receive signals to and from other wireless communications devices.
