1. A system for providing linearized operation of a RF circuit, said system comprising:

  • a first transistor differential pair;

    a second transistor differential pair;

    a control signal input port;

    a first control signal output port, wherein said first control signal output port is coupled to said control signal input port through said first transistor differential pair;

    a second attenuator control signal output port, wherein said second control signal output port is coupled to said control signal input port through said second transistor differential pair; and

    a temperature compensation circuit coupled to said control signal input port to provide temperature compensation with respect to a control signal applied thereto.
