摘要： A receiver with transmit (TX) signal cancellation is disclosed. In an exemplary design, an apparatus includes an adjustment circuit, a transformer (e.g., a balun), and a low noise amplifier (LNA). The adjustment circuit receives a version of a TX signal and provides an adjusted TX signal, which may have adjustable amplitude and/or phase. The transformer receives the adjusted TX signal and a receive (RX) signal including a leaked TX signal, attenuates the leaked TX signal in the RX signal based on the adjusted TX signal, and provides an output RX signal. The TX signal may be transmitted via a primary antenna, and the RX signal may be received via a diversity antenna. The LNA receives the output RX signal and provides an amplified RX signal. The adjustment circuit detects remaining TX signal in the amplified RX signal and adjusts the amplitude and/or phase of the adjusted TX signal to reduce the remaining TX signal.

摘要： A tracking filter for attenuating out-of-band signals and adjacent channel signals in a receiver is described. In one exemplary design, an apparatus includes a tracking filter, an LNA, and a downconverter. The tracking filter includes a summer, a filter, and an upconverter. The summer subtracts a feedback signal from an input signal and provides a first signal. The LNA amplifies the first signal and provides a second signal. The downconverter frequency downconverts the second signal and provides an output signal. The filter filters (e.g., differentiates) the output signal and provides a third signal. The filter blocks a desired signal and passes out-of-band signal components. The upconverter frequency upconverts the third signal and provides a fourth signal from which the feedback signal is derived. The tracking filter has an equivalent bandpass filter response and a variable center frequency determined based on the frequency of the desired signal.

摘要： An apparatus comprising a programmable frequency device adapted to generate a reference clock selected from a set of distinct frequency clocks, wherein the programmable frequency device is further adapted to maintain the same temporal relationship of the triggering edges of the reference clock when switching between the distinct frequency clocks. The apparatus further comprises a phase locked loop (PLL), such as a digital PLL (DPLL), that uses the selected reference clock to establish a predetermined phase relationship between an input signal and an output signal. By maintaining substantially the same temporal relationship of the reference clock when switching between distinct frequency clocks, the continual and effective operation of the phase locked loop (PLL) is not significantly disturbed while changing the reference clock. This may be used to control the power consumption of the apparatus.

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.
摘要翻译：电路接收第一信号（例如，基带信号）并将其与本地振荡器（LO）信号混合，并输出第二信号（例如，RFOUT信号）。该电路包括多个相同的混频器和分频器对（MFDP）电路。每个MFDP可以单独启用。每个MFDP包括混频器和分频器，为混频器提供本地版本的LO信号。 MFDP输出耦合在一起，使得第二信号（RFOUT）的输出功率是各种MFDP的组合输出功率。通过控制使能的MFDP的数量，控制第二信号的输出功率。由于MFDP都具有相同的布局，因此输出功率步长的精度提高。由于电路内的LO信号功率与启用MFDP的数量成比例地自动变化，因此避免了本地振荡器泄漏问题。
