TERMINOLOGY
VDD
Most positive power supply potential.
IDD
Positive supply current.
GND
Ground (0 V) reference.
CTRL
Logic control input.
VINL
Maximum input voltage for Logic 0.
VINH
Minimum input voltage for Logic 1.
IINL (IINH)
Input current of the digital input.
CIN
Digital input capacitance.
tON
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 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.
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 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.
