Parallel use of serial controls in improved wireless devices and power amplifier modules

A radio frequency module comprising:

• a first radio frequency component;
• a second radio frequency component;
• a plurality of input signal pins configured to receive at least a data input signal;
• and
• a controller including at least one output terminal, the output terminal connected to the first radio frequency component and to the second radio frequency component, the controller configured to, in a first operating mode of the radio frequency module, implement a synchronous communication protocol on the output terminal, and in a second operating mode of the radio frequency module, implement an asynchronous communication protocol on the output terminal.

A method for controlling one or more components of a radio frequency module in a wireless communication device, the method comprising:

• receiving a plurality of input signals via a serial interface of the radio frequency module;
• determining, based at least on the plurality of input signals, that the radio frequency module is in a first operating mode;
• in response to said determining that the radio frequency module is in the first operating mode, implementing a synchronous communication protocol on at least one output terminal connected to the first radio frequency component of the radio frequency module and connected to the second radio frequency component of the radio frequency module;
• determining, based at least on the plurality of input signals, that the radio frequency module is in a second operating mode;
• and
• in response to said determining that the radio frequency module is in the second operating mode, implementing an asynchronous communication protocol on the output terminal.

A wireless communication device comprising:

• a transceiver;
• an antenna;
• and
• a radio frequency module in communication with the transceiver and the antenna and having a first radio frequency component, a second radio frequency component, a plurality of input signal pins, and a controller, the plurality of input signal pins configured to receive a plurality of input signals, the controller including at least one output terminal, the output terminal connected to the first radio frequency component and to the second radio frequency component, the controller configured to, in a first operating mode, implement a synchronous communication protocol on the output terminal, and in a second operating mode, implement an asynchronous communication protocol on the output terminal.
