RF Pulse generation with RF switch

Remember the previous post where we generated PWM? We are going to use the PWM output from the TivaC microcontroller and drive an RF switch. I will be using the Minicircuits HSWA2-63DR+ SP2T switch to generate pulsed RF output. Correspondingly, A simple SP1T switch would
