GENERAL INFORM TION
A
KDI/Triangle Pin Diode attenuators continuously change the amplitude of
a microwave signal by applying a varying DC current, voltage, or digital
signal, depending upon the Model type selected. The basic current con-
trolled models do not have thermal compensation included, the voltage
controlled & digital models have linearization and/or temperature com-
pensation options.
A matched configuration of diodes keeps the VSWR low through all
values of attenuation and frequency.
Linearization is provided in some models, which produces an output
signal that is linearly proportional to the control voltage.
Temperature compensation is also provided in some models, over either
the –55 to +85 degree C range, 10–40 degree C range, or 0-70 degree C
range depending upon the Model type selected. Digitally controlled ana-
log attenuators, Model series “GA”, require an TTL binary logic input.
Standard units in the GA series have an 8 bit input producing 256 dis-
crete values of attenuation. Optional 10–12 bit logic is readily available
simply by specifying in the model number with a dash number.

Control Input Impedance:
Switching Period:
10 K ohms, 20 pf.
Standard models can be changed from any
value of attenuation to any other value in 10
microsec. Units can be provided with switch-
ing speed to 300 nanosec. on request. Speed
is related to maximum attenuation required.
That is, 32 dB models are faster than 64 dB
models. Insertion Loss will increase by a fac-
tor of 1.6 on higher speed models.
SMA standard, others on request.
GENERAL SPECIFICATIONS
R.F. Power:
To prevent self-biasing, the attenuators
should be operated at less than 100
mW CW, and 60 watts peak. Units will
not be damaged by application of 1 watt
CW or 100 watts peak.
50 OHMS.
+10 mA, maximum attenuation. 0 mA,
zero attenuation for all current controlled
models.
±15 volts at ±50 mA maximum. For all
models. 1GT, 2GT, GA (except GT)
0–10 volts produces 0–32 dB for 32 dB
models and 0–64 dB for 64 dB models.
Other values of control voltage can be
provided on request.

How to prevent WINCE 5.0 multi-image address space overlap?
In config.bib, the CE image is divided into 4 parts, for example: KERNEL.BIN, DRIVER.BIN, APP.BIN, NK.BIN. This is done so that a single image file can be upgraded later. Now the problem is that the a...
