IPITEK has been designing and building photonic
component solutions for highly demanding
applications for over 20 years. Our engineering staff
is the most experienced photonics team in the
industry and our operation in Carlsbad, California can
assist you in developing an attenuator solution that
can maximize the performance of any application.
Combine this with our high volume, low cost
manufacturing capabilities and you have an ideal
partner to help your programs and business succeed
at any level.
IPITEK in-line attenuators are manufactured using
fused biconical tapered (FBT) technology for superior
performance and reliability. Built to the highest
standards, IPITEK attentuators are 100% tested
across the entire operational passband, not just at
convenient center points. They are bi-directional
with outstanding directivity and very low excess loss.
IPITEK attenuators are field-proven and time-tested.
Available in various packages, IPITEK attenuators
are designed to facilitate a wide range of installation
parameters and environmental conditions.
IPITEK attenuators are available in 1 dB standard
increments, enabling you to balance your signal
