摘要： An output circuit with an integrated directional coupler and impedance matching circuit is disclosed. In an exemplary design, an apparatus includes a switchplexer and an output circuit. The switchplexer is coupled to at least one power amplifier. The output circuit is coupled to the switchplexer and a load (e.g., an antenna) and includes a directional coupler and an impedance matching circuit sharing at least one inductor. The output circuit performs impedance matching for the load. The output circuit also acts as a directional coupler and provides an input radio frequency (RF) signal as an output RF signal and further couples a portion of the input RF signal as a coupled RF signal. Reusing the at least one inductor for both the directional coupler and the impedance matching circuit may reduce circuitry, size, and cost of the wireless device and may also improve performance.

摘要： An impedance matching circuit with at least one tunable notch filter for a power amplifier is disclosed. The power amplifier amplifies an input radio frequency (RF) signal and provides an amplified RF signal. The impedance matching circuit performs output impedance matching for the power amplifier and includes at least one tunable notch filter. Each tunable notch filter has a notch that can be varied in frequency to provide better attenuation of an undesired signal. The at least one tunable notch filter attenuates at least one undesired signal in the amplified RF signal. The at least one tunable notch filter may include (i) a first tunable notch filter to attenuate a first undesired signal at a second harmonic of the amplified RF signal and/or (ii) a second tunable notch filter to attenuate a second undesired signal at a third harmonic of the amplified RF signal.

摘要： Techniques for reducing undesired source degeneration inductance are disclosed. In an exemplary design, an apparatus includes first and second connections. The first connection includes a first parasitic inductance acting as a source degeneration inductance of an amplifier. The second connection includes a second parasitic inductance magnetically coupled to the first parasitic inductance to reduce the source degeneration inductance of the amplifier. The amplifier (e.g., a single-ended power amplifier) may be coupled to circuit ground via the first connection. An impedance matching circuit may be coupled to the amplifier and may include a circuit component coupled to circuit ground via the second connection. The first connection may be located sufficiently close to (e.g., within a predetermined distance of) the second connection in order to obtain the desired magnetic coupling between the first and second parasitic inductances.
