DIGITALLY CONTROLLED ANALOG
PHASE SHIFTERS SERIES QQ
8, 10, OR 12 BITS
GENERAL INFORMATION
KDI/Triangle Corp. digitally controlled phase shifters vary the phase of
a microwave signal in response to a TTL compatible logic input signal.
The unit consists of an analog phase shifter, Series PQ, plus a digital
to analog converter. (See Figure 1)
A balanced stripline configuration keeps the VSWR and amplitude
change to a minimum for all values of phase.
Standard units operate with 8 bits allowing 256 discrete values of
phase. If 10 bits are required add 10 to Model No. (e.g., QQ-12-10). If
12 bits are required add 12 to Model No. (e.g., QQ-12-12).
GENERAL SPECIFICATIONS
Frequency Coverage: 0.1 to 18.0 GHz
RF Impedance: 50 OHMS.
RF Power: 10 mW peak or CW, operating. Destruct
level is 1 W, CW, 100 W peak.
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. If temperature com-
pensation is required, this can be done
on request. With compensation, the vari-
ation can be held to ±1° or ±1%,
whichever is greater, from 55°C to
+85°C. Compensation increases the cost
by 10%. The size remains the same. If
compensation is desired, add a suffix T
to the model number, e.g. (QQ-17T).
Connectors: SMA. Mating multipin connector is sup-
plied with each unit; ITT Cannon DA-15S
or equiv.
Notes:
1. The voltages required are 15 volts at 50 mA.
2. Switching speed of all models is 200 nanosec. Higher speeds on
request. For 12 bits speed is 2 microsec.
3. Monotonicity is guaranteed for all models.
4. Phase Flatness: The phase shift varies with frequency at any volt-
age setting. This variation, referred to 0° at logic 0 for each fre-
quency, is approximately 15% for octave models, 10% for
models with 25% bandwidth, and 7.5% for models with a 10%
bandwidth.
5. In order to determine the step size (least significant bit) of any
phase shifter, divide the listed value of phase shift by the number
of steps.
