Abstract: Methods and devices are disclosed driving one or more P-Intrinsic-N (PIN) diodes by receiving an input and generating a plurality of pulses based on the input, a first pulse of the plurality of pulses controls a rise time of an RF envelope generated by an RF interface and a second pulse of the plurality of pulses controls a fall time of the RF envelope generated by the RF interface. The methods and devices may further be disclosed combining the plurality of pulses to generate a drive signal, delivering the drive signal to the RF interface including one or more PIN diodes, and generating the RF envelope by driving the one or more PIN diodes with the drive signal, and the amplitude or a pulse width of the first pulse is independently adjustable from the amplitude or the pulse width of the second pulse.
