Abstract
A communication device reduces intermodulation interference in a simultaneous transmitter using a notch diplexing arrangement. The communication device has a radio front-end module with more than one transceiver for simultaneous transmission with opposing transmit (Tx) band notch filters in series with each duplexer output, and phase rotations into and out of the notch filters suitable for diplexing at the notch filter outputs.
