Fast switching radio frequency switch with reduced spurs

A radio frequency module comprising:

• a packaging substrate configured to receive a plurality of components;
• and
• at least one radio frequency switch including at least one field-effect transistor;
• and
• a gate voltage control circuit having a voltage input and a voltage output, the voltage output being coupled to a gate of the at least one radio frequency switch, the gate voltage control circuit being configured to transition a state of the at least one radio frequency switch between an ON state and an OFF state by changing a voltage supplied to a gate of the at least one field-effect transistor in multiple steps.

A wireless device comprising:

• a transceiver configured to generate a radio frequency signal;
• a front-end module in communication with the transceiver and configured to amplify the radio frequency signal to generate an amplified radio frequency signal, the front-end module including at least one radio frequency switch including at least one field-effect transistor, and a gate voltage control circuit having a voltage input and a voltage output, the voltage output being coupled to a gate of the at least one radio frequency switch, the gate voltage control circuit being configured to transition as state of the at least one radio frequency switch between an ON state and an OFF state by changing a voltage supplied to a gate of the at least one field-effect transistor in multiple steps;
• and
• an antenna in communication with the front-end module, the antenna configured to transmit the amplified radio frequency signal.
