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

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).

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).

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 Ϯ15% for octave models, Ϯ10% for
models with 25% bandwidth, and Ϯ7.5% for models with a 10%
bandwidth.
