Patent ID: 6892080

Claim:
A boost system for enhancing communication between a cellular telephone and a network base station comprising: a. a cradle that couples a cellular telephone handset to the power boost system; b. an antenna; and c. a booster amplifier electrically coupled to said cradle and said antenna, said booster amplifier having a receive side, a transmit side and a gain controller, said receive side having a low noise amplifier, a gain circuit and a buffer amplifier through which signals received from the base station are passed to the cradle and a cellular telephone coupled thereto, said transmit side having a first directional coupler and a detector which transmit a signal indicative of the cellular telephone's output power before it is boosted, a variable gain element controlled by said gain controller for controlling the output power, at least one amplifier and a second directional coupler and detector which transmit a signal indicative of the output power after it is boosted to the gain controller, said gain controller capable of processing said signals to control the variable gain element on the receive side and the variable gain element on the transmit side.
