Abstract
An apparatus comprising a plurality of switchable full step mixer unit cells, wherein each switchable full step unit cell is configured to, when the full step transceiver mixer unit cell is turned on, increase the gain experienced by an electronic signal by a full step increment, and wherein the step increment is substantially constant regardless of temperature; and at least one switchable partial step mixer unit cell configured to, when the partial step transceiver mixer unit is turned on, increase the gain experienced by the electronic signal by a predetermined step increment less than that of a full step, and wherein the partial step increment is substantially constant regardless of temperature.
