Attenuators are linear, passive transmission line compo-
nents designed to reduce the input power in a matched
system by a predetermined amount. M/A-COM offers a
complete line of 鏗亁ed coaxial attenuators designed for
laboratory, production, testing and system use. Typical
applications include VSWR reduction at the insertion
point of measurement setups, range extension of power
meters, RF path loss simulation, and isolation or power
level reduction of signal sources. The attenuator charac-
teristics of primary concern are:
a. frequency range
b. attenuation
c. average and peak power handling capability
d. operating temperature range
e. size
f. weight

All attenuators are production tested to ensure proper
operation within published speci鏗乧ations. Therefore, over
speci鏗乧ation by the user is unnecessary and reduces cost-
effectiveness. For example, if the frequency range
requirements are 2 to 4 GHz, over-specifying 鏗俛t perfor-
mance to 12.4 GHz will increase component cost with no
performance advantage.
Catalog attenuators are available in a variety of package
sizes and connector con鏗乬urations as shown on the fol-
lowing pages. The attenuator elements are designed to
provide broadband operation with low frequency sensi-
tivity and extremely stable operation at temperature
extremes.
