MD0105
Switch Capacitance
TON and TOFF Time
The typical switch On capacitance (CSW(ON)) is 21pF. This is The TON and TOFF of the MD0105 are less than 20ns, which
measured from A to B when the switch is ON. The switch provide a fast switch between the transmit mode and the re-
OFF capacitance is a function of the voltage across the T/R ceive mode. The TON and TOFF are input rise/fall time depen-
switch. The CSW(OFF) is about 12 to 19 pF for 10V to 130V of dent. The T/R switch turns ON and OFF faster when the rise
the transmit voltage.
and fall times of the transmit pulse are faster. On the other
hand, the switch turns ON and OFF slower if the rise and fall
times of the transmit pulse are slower.
