We have been designing
& manufacturing precision, passive,
mechanical Phase Shifters and Phase Trimming
devices since 1974:
-
In Series and Between Series
-
Precision MIL-STD-348 compliant
interfaces - SMA, TNC & Type N
-
3.5mm, 7mm and TK interfaces
also available
-
Proven successful in military,
commercial and space applications up
to 18GHz

In
1974, Astrolab was contracted to design a device that would
allow phase change while maintaining constant VSWR Loss values.
From this successful contract, the first in-line phase shifter
was integrated in an experimental phased array antenna system.
Since that time, Astrolab has been designing and manufacturing
these passive devices which 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. Using the materials listed
below, 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. |
