Patent ID: 7430442

Claim:
A bi-directional amplifier device that can receive and transmit RF signals compatible with one or more of the IEEE 802.11 standards, the amplifier device comprising: an amplifier circuit having a RF sensor operable to determine whether the amplifier device is receiving an RF signal or transmitting an RF signal; a switch controller operable to generate switch control signals based on the determination of said RF sensor; and an RF switch operable to transmit a transmit RF signal from a first port of the amplifier device or transmit a receive RF signal to the first port depending on a condition of the switch control signals; and an enclosure device operable to house said amplifier circuit, wherein heat generated by said amplifier circuit when in operation is sufficiently dissipated through a smooth cylindrical surface of said enclosure device such that no additional heat dissipation devices are required to ensure proper operation of said amplifier circuit.
