Patent ID: 8476961

Claim:
A switch circuit comprising: a first transistor switch; a second transistor switch; biasing circuitry including a first resistance and a second resistance and configured to receive a high control voltage and a low control voltage and to provide an on-state bias voltage to the first transistor switch and an off-state bias voltage to the second transistor switch, the on-state bias voltage being a difference between a product of the first resistance and the high control voltage and a product of the second resistance and the low control voltage, the off-state bias voltage being a difference between a product of the first resistance and the low control voltage and a product of the second resistance and the high control voltage, the off-state bias voltage having a magnitude that is different than a magnitude of the on-state bias voltage by an amount sufficient to yield at least one of a harmonic emission associated with the switch circuit that is less than a selected emission level and a linearity associated with the switch circuit that is greater than a selected linearity level.
