Abstract
A distributed antenna device includes a plurality of transmit antenna elements, a plurality of receive antenna elements and a plurality of amplifiers. One of the amplifiers is a power amplifier operatively coupled with each of the transmit antenna elements and mounted closely adjacent to the associated transmit antenna element, such that no appreciable power loss occurs between the power amplifier and the associated antenna element. At least one of the amplifiers is a low noise amplifier and is built into the distributed antenna device for receiving and amplifying signals from at least one of the receive antenna elements. Each power amplifier is a relatively low power, relatively low cost per watt linear amplifier chip.
