The gSSS0013 is a Single Pole Single Throw
Switch with wideband characteristics. It
features good insertion loss and excellent
isolation up into the W-band. The return
loss is also good across the entire band 40 to
+110 GHz.
It may also be used as a voltage variable
attenuator.

Figure 3. (Left) Attenuation vs control voltage at 71 to 86 GHz. (Right) In-band slope at different attenuations
settings from 71 to 86 GHz.
Bias should first be applied to the gates (VG…) followed by the drains (VD…). The gate voltages
must be adjusted within the min/max range indicated in Error! Reference source not found.-5 to
obtain the specified drain currents. The drain currents are stated with all input signals off.
