Rf system for reducing intermodulation (im) products

A mobile terminal comprising:

• an antenna;
• a receiver front end;
• an RF system having a first RF port coupled to the receiver front end and at least one RF port coupled to the antenna, the RF system comprising:
• a first nonlinear element;
• a second nonlinear element, wherein the second nonlinear element generates inherent IM products and the first nonlinear element is adapted to generate compensating IM products, or wherein the first nonlinear element generates inherent IM products and the second nonlinear element is adapted to generate compensating IM products;
• and
• a first phase shifter adapted to provide a phase shift that results in around 180° of phase shift between the inherent IM products and the compensating IM products, the first phase shifter being coupled between the first nonlinear element and the second nonlinear element;
• and
• a control system communicatively coupled to a control terminal for selecting switching modes of the RF system.
