`A'
GENERAL INFORMATION
An analog Phase Shifter continuously changes the
phase of a microwave signal by varying a DC
voltage. Since the DC voltage applied to the diode is
reverse bias, the current drain is negligible (typically
less than 10µA). A balanced stripline configuration
keeps the VSWR and amplitude ripple to a minimum
for all values of phase.

Will vary the phase of any Model
over its minimum phase shift
listed.
Temperature: The unit can be used over a -55°
C to + 85° C range. The Phase
will change either ±5° or ±5%,
whichever is Greater.
Speed: Series PQ Phase shifters can be
driven from any phase value to
any other phase value in 10
nanoseconds.

2) The Phase shift varies with frequency at any
voltage setting. This variation, referenced to 0° at
0 Volts for each frequency, is approximately
± 5% for octave models, ±
1
10% for models with
25% bandwidth, and ±7.5% for models with
10% bandwidth. Phase flatness of the PQ-65 &
PQ-74 is ±25%

3) A Connector, (SMA Female) is available in place
of the bias pin at no extra charge. This will be
placed at the center of the surface marked “H”
on the drawing. This is the .38 x “A” surface. If
an SMA Female is desired, add the suffix C to the
model number (e.g., PQ-45C).
4) Linearization models available, call for outline
and details.
