    Abstract: Exemplary embodiments are directed to a transmitter with a power amplifier and a switched output matching circuit implementing a plurality of output paths for a plurality of operating modes is described. The power amplifier receives an input RF signal and provides an amplified RF signal. An output matching network performs impedance transformation from low impedance at the power amplifier output to higher impedance at the matching network output. The plurality of output paths are coupled to the output matching network. Each output path provides a different target output impedance for the power amplifier and routes the amplified RF signal from the power amplifier to an antenna when that output path is selected. Each output path may include a matching network coupled in series with a switch. The matching network provides the target output impedance for the power amplifier when the output path is selected. The switch couples or decouples the output path to/from the power amplifier.

    Abstract: Techniques for providing adjustable gain in an amplifier. In an aspect, a composite amplifier having adjustable gain includes a plurality of amplifiers coupled in parallel, wherein each of the amplifiers may be turned on or off to adjust the overall gain of the composite amplifier. Each amplifier may include an input transistor and at least two cascode transistors. To turn each amplifier off, the gate voltage of a second or lowermost cascode transistor coupled to the input transistor may be grounded, and the gate voltage of a first cascode transistor coupled to the output voltage may be coupled to a first turn-off voltage to reduce the drain-to-gate voltage drop across the first cascode transistor. Further aspects provide for decoupling a capacitor coupled to the gates of the cascode transistors from AC ground when the amplifier is turned off.

In an exemplary design, an apparatus includes first, second, and third circuits (580a, 580b, 560a). The first circuit (580a) passes a first radio frequency (RF) signal to an antenna (598) when a first signal path (522a) is selected. The second circuit (580b) passes a second RF signal to the antenna (598) when a second signal path (522b) is selected. The third circuit (560a) is selectively coupled to the first circuit (580a), e.g., via a switch (562a). The first and third circuits (580a, 560a) form a filter for the second RF signal (e.g., to attenuate a harmonic of the second RF signal) when the second signal path (522b) is selected and the first signal path (522a) is unselected.
