A power attenuator with at least one coupling port. The coupling port may be
provided
to monitor input power levels, out put power levels, or other operations of the
power attenuator. One or more coupling ports may be located on the power attenuator
input part to monitor input power levels and/or on the power attenuator output
part to monitor output power levels. The coupling port(s) may be coupled to the
main RF path by resistive coupling or reactive coupling. The coupling port(s) allow
monitoring of the RF signal passing through the power attenuator to detect for
incipient failures.
