Additional Details:

The SWD-109's key specifications typically include frequency range, insertion loss, isolation, switching speed, input power handling, and control voltage. The insertion loss is the signal attenuation through the switch when it is in the ON state, while isolation is the signal attenuation between the input port and the OFF port. Switching speed is the time it takes for the switch to change state from ON to OFF or OFF to ON. The control voltage is the voltage required to switch the device. The device is often controlled via a positive voltage for one path and 0V for the other path. Its high performance characteristics make it well-suited for demanding applications requiring precise signal control.
