| 1. An insertion loss control limit circuit operable to supply an insertion loss limit to a coupled power feed circuit, the
insertion loss control limit circuit comprising:
a first amplifier operably coupled to a pair of network power signals, wherein the amplifier is operable to generate a power
estimate signal associated with the network power signals;
a rectifier operable to convert the power estimate signal into a single ended rectified power estimate; and
a loop filter operable to produce an insertion loss control limit, wherein the insertion loss control limit is based on the
received pair of network power signals.
