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 615 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 615% for octave models, 610% for
models with 25% bandwidth, and 67.5% 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.
