ATTENUATORS, PIN DIODE
“PHASE-FREE” 0.25–18 GHz
SERIES DF & FF
GENERAL INFORMATION:
KDI/Triangle’s phase free Pin diode attenuators change the amplitude of
a microwave signal with matched (low) VSWR over the full attenuation
range, and with minimum phase shift change.The units are supplied with
either an analog or with a digital control input, with a dynamic attenuation
range of 32 dB minimum. Standard digital units are supplied with 8 TTL
logic inputs (bits) and therefore can produce 256 discrete values of atten-
uation. Units with 10 or 12 bits can be provided as specials.
GENERAL SPECIFICATIONS:
Frequency Range:
0.25 to 18.0 GHz
RF Impedance:
50 OHMS
D.C.Voltage:
± 15 volts at ± 50 mA
Logic (DF Series)
TTL compatible
No. of Bits:
8 L.S.B. = 0.125 dB.
Attentuation:
31.875 dB
Control Range: (FF Series)
0-10 volts produces 0-32 dB. Other control
voltages can be provided on request.
Control Input Impedance
10 K Ohms, 20 pf
Accurac y/Frequenc y Flatness
For octave models, the frequency sensi-
tivity including digital settability is typically ±
0.8 dB to 20 dB; ± 1.25 dB to 32 dB over
the frequency range.Narrow band units are
proportionally more accurate.
RF Power:
100 mW CW 60 watts peak operational.
Units will not be damaged by application of
1 watt CW 100 watts peak.
Temperature In ormation:
Operating temperature from -55°C to +85°C
Temperature Stability:
A) Standard: ±0.3 dB from + 10°C to +40°C
B) ± 0.5 dB to 20 dB and ±0.75 dB to 32 dB
can be provided from -54°C to +85°C.If this
stability is desired, add a suffix TT to model
number.for example, if the DF-74 is desired
with temperature compensation, it is
ordered as DF-74-TT.
Connecto s:
SMA standard. A mating multipin connector
can be supplied with each unit upon request.
ITT Cannon MDB-1-15SSL or equivilent.
Switching Speed:
Response time of all models is 10
microsec. Faster models (to 150
nanosec.) can be quoted on request.
Linearization:
Any of the models “FF” can be supplied
with a linearizer by adding a prefix 2.For
example, if the FF-47 is desired with a
linearizer, it is ordered as a 2-FF-47.The
overall accuracy including linearity and
frequency sensitivity is then ±0.75 dB to
20 dB and ±1.25 dB to 32 dB.

Notes:
1. Harmonic Distortion: Approximately –50 dBc for Pin
0 dBm at a frequen-
cy of 1.0 GHz for most units. This value improves by approximately 10 dB
per octave as the frequency increases; however, since this value is depen-
dent on bandwidth of the unit, power input, and switching speed required,
the factory should be consulted if harmonic content is an important system
requirement.
2. The phase shift over the center half of the frequency range is 1/2 of the
value listed, e.g.: the phase shift of the FF-47 is ±5° from 2.5 to 3.5 GHz
(0–20 dB). See Fig. 2
3. Other configurations (up to 12 Bits) or units with different attenuation
values can be quoted on request.
