System and method for controlling radio frequency transmissions from an electronic device

An electronic circuit for reducing leakage of radio frequency signals from a power amplifier of a wireless communication device, comprising:

• a printed circuit board (PCB) having the power amplifier mounted on the PCB;
• a first electrical track in the PCB connecting to a high band power input terminal of the power amplifier;
• a first capacitor connected to the first electrical track and a ground reference in the PCB, the first capacitor reducing transmission of radio frequency signals from the high band power input terminal of the power amplifier;
• a first high filter choke having a first connection connecting to the first electrical track and the first capacitor and a second connection connecting to a battery terminal;
• a second capacitor connected to the first electrical track between the input terminal and the first high filter choke;
• a second electrical track connected to a low band power input terminal of the power amplifier;
• a second high filter choke a having a first end connected to the second electrical track and a second end connected to the battery terminal;
• a third capacitor connected to second first electrical track between the low band power input terminal and the second high filter choke;
• and
• a fourth capacitor connected to the first and second high filter chokes and the battery terminal.
