1. PIN diode DC reverse voltage to maintain high resistance in the OFF PIN diode is determined by RF frequency, incident power, and VSWR

as well as by the characteristics of the diode. The minimum reverse bias voltage values are provided in this datasheet. The input signal

level applied for small signal testing is approximately 0 dBm.

2. Switching time (50% TTL - 10/90% RF Voltage) is a function of the PIN diode driver performance as well as the characteristics of the

diode. An RC “current spiking network” is used on the driver output to provide a transient current to rapidly remove stored charge from the

PIN diode. Typical component values are: R = 50 to 220 Ω and C = 470 to 1,000 pF. MACOMs MPD2T28125-700 is the recommended PIN

diode driver to interface with the MSW2000-200, MSW2001-200 SP2T and MSW2002-200 switches. Its data sheet is available.
