Abstract
A system for amplifying output transmitted power of a mobile battery powered radio transceiver includes a secondary voltage source, multiple power amplifiers, a central processing unit to control the amplification of the output transmitted signal, and a switch to detect the presence of the radio transceiver. The system includes a method for compensating for the signal loses associated with cabling used in the installation of the amplifying circuitry in an automobile application. According to the first preferred embodiment of the present invention, the method for compensating for signal losses is a manually configured bank of switches. When the amplifying circuitry is installed in the automobile application, the bank of switches is set to specify the amount of loss compensation needed. Multiple amplifiers are used for amplification of the output transmitted signal when the radio transceiver is operating at different frequencies. Gain of the amplifying circuitry remains fixed and the central processing unit will control the output of the portable transceiver, therefore changing the input level into the amplifying circuitry and hence the output level of the amplifying circuitry.
