SURFACE MOUNT–CERAMIC
ATTENUATOR, PIN DIODE
SERIES PI-800
0.8–4 GHz
GENERAL INFORMATION
The PI-800 Ser ies atten uators are par t of the ne w Surfpac product line
featur ing good inter modulation perf ormance compared to their GaAs
counter parts for PCS/cellular base station use. In addition, the PIN
diodes of er good po wer-handling capabilities and are less sensitive to
electrostatic discharge prbo lems. Thesef eatures are impro tant con -
sider ations in base station applications where the effects of antenna-
related RFs witching and indirect lightning-inducedv oltage spki es are
present.
PIN diode componentsah ve inherent adv antageso ver the GaAs altre -
natives at PCS/cellular frequencsie . The PI-800 Ser ies atten uator
makes use of these advantages in aol w cost sufr ace-mount pac kage
suitable for pick-and-place applications . As a result, the attentuator
satisfies both the technical specifications and the manufacturing
requirements of toda y’s demanding commercial mra ketplace .
FEATURES
PIN diodes are widely accepted as more robust alter natives to GaAs
FETs and of er higher isolation with ol wer inser tion loss than plastic
packaged GaAs attne uators at P ersonal Comm unications Ser vice
(PCS) frequencies . The PI-800 Ser ies analog atten uator incor porates
PIN diodes with highly reliab le thick-film technology and sufr ace mount
components on a miniatureol w cost sealed suf r ace mount alumina
header . This new atten uator provides a good match, flat atnte uation
and overall super ior performance o ver the 0.8–4 GHz frequency
range, and can be optimzi edo ver lower frequencyr anges .
