TERMINOLOGY

Most positive power supply potential.

Positive supply current.

GND

Ground (0 V) reference.

CTRL

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.

Off Isolation

The attenuation between input and output ports of the switch

when the switch control voltage is in the off condition.

Insertion Loss

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.

Return Loss

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.

voltage standing wave ratio (VSWR) indicates the degree of

matching present at a switch RF port.

Video Feedthrough

The 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.
