HUBER+SUHNER phase shifters allow phase change while maintaining constant VSWR and insertion loss values. These passive devices have proven to be successful in aerospace, missile, and satellite programs. The construction of all phase shifters and trimming devices incorporate fine gauge threads for precise tuning. Phase shifters are terminated with precision interfaces per MIL-STD-348 including SMA, TNC, and N (in series and between series). However, custom devices can be manufactured using other interfaces.
