MINIATURE ANALOG DIODE
PHASE SHIFTERS
0.1–8.0 GHz
GENERAL INFORMATION
The MQ Series are miniature analog phase shifters that continuously
change the phase of a microwave signal by varying a D.C. voltage. Since
the D.C. voltage applied to the diode is a reverse bias, the current drain
is negligible (typically less than 10 microamperes). A balanced stripline
configuration keeps the VSWR and amplitude ripple to a minimum for all
values of phase shift.

Temperature Information:
The units can be used over a –55°C to
+85°C temperature range. However, the
phase will change either 5° or 5%,
whichever is greater.
Switching Speed:
Series MQ phase shifters can be driven
from any phase value to any other value
in 10 nanoseconds.
