An FET RF signal detector circuit comprising two unbalanced differential transistor pair circuits is disclosed. A current mirror output circuit is included for generating an output current derived from currents flowing in the differential transistor pair circuits. The first unbalanced differential transistor pair circuit comprises two branches, each with a respective tail, and a first variable resistor between the branch tails. The first unbalanced differential transistor pair circuit connects to a first current source tail arrangement. The second unbalanced differential transistor pair circuit comprises two branches, each with a respective tail, and a second variable resistor between the branch tails. The second unbalanced differential transistor pair circuit connects to a second current source tail arrangement.

FET RF power detector

A Lange coupler comprises an unbroken peripheral ground conductor surrounding input, through, coupled and isolated conductor strips coupled to input, through, coupled and isolated ports of the Lange coupler respectively, wherein the peripheral ground conductor and input and through conductor strips are arranged on a first metal layer.
