摘要： An amplifier circuit includes a gain controller, a first amplifier, and a second amplifier which is coupled in series to the first amplifier, the second amplifier comprising a plurality of amplifying units. The gain controller is configured to receive a desired gain value and provide, based on the received desired gain value, a gain adjust signal to the first amplifier, and activate, based on the received desired gain value, a certain combination of amplifying units of the plurality of amplifying units of the second amplifier, such that a combined gain of the first amplifier and the active amplifying units of the second amplifier corresponds to the received desired gain value

摘要： A transmitter includes a transformer that is configured to transform a baseband signal into an amplitude information signal and a phase information signal. The transmitter includes a ramping control unit configured to generate a power control signal. The transmitter includes a mixer that is configured to combine the amplitude information signal with the power control signal and produce a second amplitude information signal. The transmitter includes a modulator that is configured to modulate the second amplitude information signal on the phase information signal and produce an output signal.
