Most positive power supply potential.
Positive supply current.
Ground (0 V) reference.
Logic control input.
Maximum input voltage for Logic 0.
Minimum input voltage for Logic 1.
Input current of the digital input.
Digital input capacitance.
Delay between applying the digital control input and the output switching on.
Delay between applying the digital control input and the output switching off.
Rise time. Time for the RF signal to rise from 10% to 90% of the ON level.
Fall time. Time for the RF signal to fall from 90% to 10% of the ON level.
The attenuation between input and output ports of the switch when the switch control voltage is in the
OFF condition.
The attenuation between input and output ports of the switch when the switch control voltage is in the
ON condition.
1 dB compression point. The RF input power level at which the switch insertion loss increases by 1 dB over its
low level value. It 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, whereby 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 VSWR can be calculated from conversion charts. VSWR (voltage standing wave ratio)
indicates degree of matching present at a switch RF port.
Video Feedthrough Spurious signals present at the RF ports of the switch when the control voltage is switched from high to low
or low to high without an RF signal present.
