V2 - Modify the switch HMC239AS8 driver circuitry
Speed up the switch (HMC239AS8) control inputs by reducing the resistor (4.7k and 10k) values in the switch driver circuitry. Reducing the resistor values increases the rise and fall times of the switch control signals but it creates more noise/distortion to the spectrum. Find a trade-off between the distortion and switching time.
