A distributed antenna system comprising a plurality of antenna elements, duplexers and amplifiers, each amplifier and duplexer operatively coupled with one of said antenna elements and mounted closely adjacent to the associated antenna element in such a manner as incidences of insertion loss, noise and system failure are reduced.

Distributed active transmit and/or receive antenna

A base station for a wireless communications system having a tower-mounted amplifier system with a low-noise amplifier transistor and a thermoelectric cooler that reduces the operating temperature of the low-noise amplifier transistor. The amplifier system has additional heat-generating components, such as filters, and additional electrical components mounted on a substrate to which the low-noise amplifier transistor is mounted. These heat-generating components are thermally isolated from the cold side of the thermoelectric cooler. As a result, the cooling capacity and electrical power requirement for the thermoelectric cooler is significantly reduced because only the low-noise amplifier transistor is cooled.

Thermoelectric cooling of low-noise amplifier transistors in wireless communications networks

A distributed antenna array comprising a plurality of antenna elements, and a plurality of power amplifiers, each power amplifier being operatively coupled with one of said antenna elements and mounted closely adjacent to the associated antenna element, such that no appreciable power loss occurs between the power amplifier and the associated antenna element, each said power amplifier comprising a relatively low power, linear power amplifier.
