Digitally Controlled Analog Phase Shifter
Data Sheet Revision Date: 12/19/2015
The most important thing we build is trust
DESCRIPTION:
Cobham Signal & Control Solutions’ digitally controlled Phase Shifters vary the
phase of a Microwave signal in responce to a TTL compatible logic input signal.
The unit consists of an analog phase shifter, series PQ, plus a digital to analog
converter. A balanced Strip line 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.

Digitally Contolled Analog Phase Shifter
NOTES:
ELECTRICAL SPECIFICATION:
1. The voltages required are ±15V @ 50mA.
DC Supply:
+15 V ± 0.5 V @ +50 mA
-15 V ± 0.5 V @ -50 mA
Control:
8 Bits command
Logic Control:
TTL/HMOS
2. The Phase shift varies with frequency at any voltage
setting. This variation, referenced to 0° at logic 0 for
each frequency, is approximately ±15% for octave
models, 10% for models with 25% bandwidth, and
±7.5% for models with 10% bandwidth.
3. Switching speed on all models is 200 nS.
ENVIRONMENTAL SPECIFICATIONS*:
MIL-E-5400, MIL-STD-202, MIL-E-16400
4. Monotonicity is Guaranteed.
5. Least Significant BIT = Total Phase Shift divided by
the number of steps. 8 BITS = 256 steps.
