A power ramping circuit for use in the transmit path of a radio frequency (RF) circuit. The power ramping circuit includes parallel connected transistors used as logarithmic resistor attenuators for adjusting current to a mixer circuit in the transmit path. The parallel connected transistors can be sized differently, and are sequentially turned off to gradually increase the current provided to the mixer circuit. A ramp control circuit controls the parallel connected transistors in response to either an analog signal or a digital signal.
