Patent ID: 7280808

Claim:
A wireless communications device comprising: a power amplifier configured to transmit information to a wireless communications network during a first time interval and configured to avoid transmitting information during a second time interval; a circuit substrate coupled to the power amplifier; a power source configured to provide power to the power amplifier; and first and second conductors, coupled to the power amplifier and to the power source, having respective overlapping and non-overlapping portions on the circuit substrate; wherein the first conductor is configured to conduct a first current in a first direction to the power amplifier and the second conductor is configured to accept a second current in a second direction, opposite the first direction, from the power amplifier, wherein the first and second currents comprise first and second Direct Currents (DC) switched on/off at a frequency in a range between about 50 Hz and about 217 Hz responsive to operation of the power amplifier.
