Rev. C | Page 10 of 16 TERMINOLOGY VDD Most positive power supply potential. IDD Positive supply current. GND Ground (0 V) reference. CTRL Logic control input. V INL Maximum input voltage for Logic 0. VINH Minimum input voltage for Logic 1. I INL (IINH) Input current of the digital input. C IN Digital input capacitance. t ON Delay between applying the digital control input and the output switching on. tOFF Delay between applying the digital control input and the output switching off. tRISE Rise time; time for the RF signal to rise from 10% to 90% of the on level. tFALL Fall time; time for the RF signal to fall from 90% to 10% of the on level. Off Isolation The attenuation between the input and output ports of the switch when the switch control voltage is in the off condition. Insertion Loss The attenuation between the input and output ports of the switch when the switch control voltage is in the on condition. P–1 dB 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. IP3 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 (voltage standing wave ratio) can be calculated from conversion charts. VSWR indicates the 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.
