Off Isolation
Rise Time. Time for the RF signal to rise from 10% of the on level to 90% of the on level.
Fall Time. Time for the RF signal to fall from 90% of the on level to 10% of the on level.
Transition Time. Delay between applying the digital control input and the output switching on.
The Attenuation between Input and Output Ports of the Switch when the Switch Control Voltage is in the Off Condition.
Insertion Loss
Crosstalk
The Attenuation between Input and Output Ports of the Switch when the Switch Control Voltage is in the On Condition.
Measure of Unwanted Signal Coupled through from One Channel to Another as a Result of Parasitic Capacitance.
P–1 dB
IP3
Return Loss
1 dB Compression Point. The RF input power level at which the switch insertion loss increases by 1 dB over its low level
value. P–1 dB is a measure of how much power the on switch can handle before the insertion loss increases by 1 dB.
Third-Order Intermodulation Intercept. This is a measure of the power in false tones that occur when closely spaced
tones are passed through a switch, and the nonlinearity of the switch causes these false tones to be generated.
The Amount of Reflected Power Relative to the Incident Power at a Port. Large return loss indicates good matching. By
measuring return loss, the voltage standing wave ratio (VSWR) can be calculated from conversion charts. VSWR indicates
the degree of matching present at a switch RF port.
