Abstract
A system divides a signal into first and second portions and transmits the first and second portions through different signal paths between a first port and a second port. Each of the signal paths comprises an amplifier arranged in sequence with a passive device. Phase shifters may be included in each of the signal paths to produce cancellation of intermodulation products by destructive interference.
