The ADG918 is an absorptive (matched) switch having50 Ω terminated shunt legs, whereas the ADG919 is a reflectiveswitch. These devices are designed such that the isolation ishigh over the dc to 1 GHz frequency range. They have on-boardCMOS control logic, thus eliminating the need for externalcontrolling circuitry. The control inputs are both CMOS andLVTTL compatible. The low power consumption of theseCMOS devices makes them ideally suited to wireless andgeneral-purpose high frequency switching 0–3.0–40–3.210k–50VDD 2.5VTA 25 C100k1M10M100MFREQUENCY (Hz)1G10G03335-004ISOLATION (dB)VDD 2.5VTA 25 C–0.4INSERTION LOSS (dB)0–10 43 dB off isolation at 1 GHz.0.8 dB insertion loss at 1 GHz.Tiny 8-lead MSOP/LFCSP.Figure 3.

The RF input power level at which theswitch insertion loss increases by 1 dB over the low level value.It is a measure of how much power the on switch can handlebefore the insertion loss increases by 1 dB.VINHMinimum input voltage for Logic 1.IINL (IINH)Input current of the digital input.CINDigital input capacitance.tONDelay between applying the digital control input and the outputswitching on.tOFFDelay between applying the digital control input and the outputswitching off.tRISERise time; time for the RF signal to rise from 10% to 90% of theon level.IP3Third order intermodulation intercept. This is a measure of thepower in false tones that occur when closely spaced tones arepassed through a switch, whereby the nonlinearity of the switchcauses these false tones to be generated.Return LossThe amount of reflected power relative to the incident power ata port. Large return loss indicates good matching. By measuringreturn loss, the VSWR (voltage standing wave ratio) can becalculated from conversion charts. VSWR indicates the degreeof matching present at a switch RF port.Video FeedthroughSpurious signals present at the RF ports of the switch when thecontrol voltage is switched from high to low or low to highwithout an RF signal present.Rev.
