ANALOG DIODE
PHASE SHIFTERS
CONTINUOUSLY VARIABLE — 0.1–18 GHz
GENERAL INFORMATION
An analog phase shifter continuously changes 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 microamps). A balanced stripline configuration
keeps the VSWR and amplitude ripple to a minimum for all values of
phase.

D.C. Voltage:
0.1 to 18.0 GHz
50 OHMS.
0 volts to +28 volts (standard), or 0 volts
to –28 volts (optional) will vary the phase
of any of the models over the minimum
phase shift listed
10 mW peak or CW, operating. Destruct
level is 1 W, CW, 100 W peak.
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. If temperature com-
pensation is required, this can be done on
request. With compensation, the variation
can be held to ±1° or ±1%, whichever is
greater, from –55°C to +85°C. The size
remains the same. If compensation is
desired, add a suffix T to the model num-
ber (e.g., PQ-17T).
Series PQ phase shifters can be driven
from any phase value to any other value
in 10 nanoseconds. With linearizers, the
response time is 50 nanoseconds. With
temperature compensation the response
time is 100 nanoseconds.

Notes:
1. LINEARIZATION: For phase shifters with linearizers add a suffix L
to the model number (e.g., PQ-23L). Linearity is ±2.0° for phase
shifters for 150° or less, and ±4° for phase shifters between 150°
and 360°. With linearization, DC voltages of ±15V at ±30mA are
required. The control voltage is 0–10 volts. A control voltage of 0–5
volts can be supplied at no additional cost, by adding a suffix 5 to
the model number (e.g. PQ-23L5). Linearity is measured at f
c
.
2. PHASE FLATNESS: The phase shift varies with frequency at any
voltage setting. This variation, referenced to 0° at 0 volts for each
frequency, is approximately ±15% for octave models, ± 10% for
models with 25% bandwidth, and ±7.5% for models with a 10%
bandwidth.
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 F on the drawing. This is the 0.38
×
A surface. If a SMA
Female is desired, add suffix C to the model number (e.g., PQ-
23C).
4. Monotonicity guaranteed for all models.
