Fixed Coaxial Attenuators
Overview
V2.00
Attenuation
The term attenuation is generally used rather loosely and
often means
insertion loss
or, to be even more specific
characteristic insertion loss.
Insertion loss is the ratio of
the power delivered to a matched load by a matched
generator before and after the insertion of a component
in the line. Insertion loss is actually a combination of two
losses: mismatch loss (reflective) and attenuation
(dissipative). Mismatch loss is the ratio of power that
would be absorbed by the device if it were perfectly
matched to the actual power absorbed by the device
with its mismatch in impedance. Attenuation is the ratio
of power into a component to the power out under
perfectly matched conditions and represents the actual
power dissipated within the component. Where a
component is perfectly matched to the line and the load,
the mismatch loss is zero, and the attenuation and
insertion loss are the same.
Average Power
The maximum average power is the maximum specified
input power applied for a minimum of one hour at a
specified operating temperature (25°C for OSM fixed
coaxial attenuators) with the output terminated in the
characteristic impedance which will not permanently
change the specified properties of the attenuator after
return to ambient temperature at a power level 20 dB
below the maximum specified input power.
Derating is necessary if the attenuator is operated at
higher temperatures. See derating curve and
specifications.
Peak Power
The maximum peak power at a specified pulse width
and average power which when applied for a minimum
of one hour while the output is terminated in the
characteristic impedance will not permanently change
the specified properties of the attenuator. The pulse
width used to test OSM attenuators is 5 microseconds.
Temperature Coefficient
The maximum change of insertion loss in dB per °C
from 20°C over the maximum operating temperature
range. To obtain
dB, multiply the temperature
coefficient by the value in dB and by the temperature
change from 20°C in °C.

section, M/A-COM can supply special attenuators to suit
your particular needs. Some typical specials are listed
below. Complete facilities are maintained for the testing
and documentation requirements of high reliability
aerospace applications.
