Abstract
Radio frequency transmitters and transmitting methods control amplification of a radio frequency power amplifier, attenuation of a voltage standing wave ratio (VSWR) attenuator, and attenuation of a power control attenuator, in response to power control signals. Wide ranges of power control, for example up to 60 dB or more, may thereby be provided without unduly increasing transmitter complexity or power consumption.
