DIGITAL DIODE
PHASE SHIFTERS
0.25–5.1 GHz
GENERAL INFORMATION
KDI/Triangle’s switched line digital phase shifters are controllable by
binary logic. If a 360° phase shifter having sixteen discrete steps is
required, then four logic lines are employed. The smallest phase incre-
ment will be 22.5°. This type of phase is illustrated below.

DESCRIPTION
Two advantages of the switched line phase shifter, Series DP, over the
digitally controlled analog phase shifter, Series QQ, are faster switching
speed, and less change with temperature. The disadvantage is that
phase increments smaller than 5.63° are impractical, while the digitally
controlled analog device can have increments as small as 0.088°
(12 bits) and maintain monotonicity.
ELECTRICAL SPECIFICATIONS
All performance characteristics, especially insertion loss, can be
improved over narrower frequency bands.

+5 volts at 70 mA, and –5 volts at 70 mA per
bit. For each logic line at logic 0, +70 mA is
drawn from the +5 V supply and 10 mA from
the –5V supply. For each logic line at
logic, 1 –70 mA is drawn from the 5V

supply and 10 mA from the +5 V supply

Temperature Information:
Operating temperature from –55°C to
+85°C.
Switching Speed:
The switching speed of all models in 500
nanoseconds (750 nanoseconds includ-
ing storage and delay time). Any model
can be switched in 15 nanoseconds (35
nanosec. including storage and delay
time) if required. However, the insertion
loss will increase by 30%. If 15 nanosec-
onds is required add-1 to the model no.
