1. A radio frequency trimmer circuit comprising:
an input terminal configured to receive a radio frequency signal;
an output terminal configured to output the radio frequency signal;
a control input configured to receive a control signal;
at least one impedance element; and
at least one transistor configured to control at least one of a magnitude trim and a phase trim of the radio frequency signal to selectively connect the impedance element onto a path between the input and output terminals.
