See Appendix for MIL-STD-883 screening option.
* All specifications apply with 50 ohm impedance connected to all RF por ts
with 0 and -5 VDC control voltages.
† Faster switching speed can be achieved with enhaned driver waveform.
** For the SW-227 and SW-228 only, when an RF output is ‘OFF’ it is
shorted to case ground.
