Abstract
A wireless LAN RF module uses a low power transistor switchable voltage divider circuit to control the bias input of a GaAs MESFET output power amplifier. This bias control circuit provides stable, high speed on-off switching of the power amplifier stage by applying low power bias voltages to the MESFET gate input, rather than by interrupting the high power MESFET drain to Vdd circuit.
