1. A radio frequency (RF) circuit comprising:
a transistor element comprising an input transistor having a gate terminal coupled to an input terminal, and a drain terminal coupled to an output terminal; the transistor being configured to receive an input RF signal at the input terminal;
wherein
an effective width of the transistor element is configured to be selectively adjusted based on a detected bandwidth of the input RF signal to improve handling of the input RF signal.
