Abstract
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.
Claims23
A power attenuator, comprising:
- an output connector for enabling the propagation of one or more RF signals along a main RF path through an input connector, a body, and said output connector;
- and
- at least one coupling port, coupled to the main RF path, for sampling the one or more RF signals.
A method of detecting an incipient failure, comprising:
- receiving one or more RF signals;
- sampling the one or more RF signals using at least one coupling port;
- and
- monitoring the samples for the incipient failure.
