Passive intermodulation (PIM)

From HUBER+SUHNER AG

Intermodulation is a system characteristic, where new frequencies
in the output are created. A common technical realisation for intermodulation
is to use non-linear components, such as diodes.
While intermodulation is important for certain applications, it is not
in every case. One important example is a communication system,
where transmission and reception paths are combined. In this case,
no distortion of the received signal by the transmission signal is
expected. Unfortunately, perfect linear components do not exist.
Even passive components do not behave perfectly linearly. In this
case, the term Passive Intermodulation (PIM) is used.

Products & Services
Delay Lines
Delay lines are devices used to slow down a signal by a time interval in an electrical network. There are two basic delay line technologies: passive and active. 
RF Power Dividers and RF Power Combiners
RF power dividers and RF power combiners are circuits that accept input signals and deliver multiple outputs that are equal in phase and amplitude. There are two basic product categories: passive and active.
RF Adapters
RF adapters are used to connect different waveguides and/or coaxial cables. They are passive devices that direct radio frequency (RF) signals with minimal return loss.
Antennas
Antennas are structures or devices used to collect or radiate electromagnetic waves.
RF Attenuators
RF attenuators are circuits that reduce the power level of a signal by a certain amount (gain), with little or no reflection. They reduce the output signal with respect to the input and measure the power reduction in decibels (dB).
