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.
