PARAMETER DESCRIPTION (continued)
SYMBOL DESCRIPTION
C
COM(ON)
Capacitance at the COM port when the corresponding channel (COM to NC or COM to NO) is ON
C
COM(OFF)
Capacitance at the COM port when the corresponding channel (COM to NC or COM to NO) is OFF
C
I
Capacitance of control input (IN)
OFF isolation of the switch is a measurement of OFF-state switch impedance. This is measured in dB in a specific
O
ISO
frequency, with the corresponding channel (NC to COM or NO to COM) in the OFF state.
Crosstalk is a measurement of unwanted signal coupling from an ON channel to an OFF channel (NC to NO or NO to
X
TALK
NC). This is measured in a specific frequency and in dB.
BW Bandwidth of the switch. This is the frequency where the gain of an ON channel is – 3 dB below the DC gain.
Total harmonic distortion describes the signal distortion caused by the analog switch. This is defined as the ratio of root
THD
mean square (RMS) value of the second, third, and higher harmonic to the absolute magnitude of fundamental harmonic.
