Parameter

Description

Most Positive Power Supply Potential.

Positive Supply Current.

GND

Ground (0 V) Reference.

INx

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% 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.

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.

Crosstalk

Measure of Unwanted Signal Coupled through from One Channel to Another as a Result of Parasitic Capacitance.

1 dB Compression Point. The RF input power level at which the switch insertion loss increases by 1 dB over its low level

Third-Order Intermodulation Intercept. This is a measure of the power in false tones that occurs 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. VSWR (voltage standing wave ratio) indicates

the degree of matching present at a switch RF port.

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.
