SYSTEM FOR AMPLIFYING WAVE SIGNAL LEVEL OF MOBILE TELEPHONE TERMINAL

摘要

PURPOSE: A system for amplifying wave signal level of mobile telephone terminal is provided to keep a call in high quality in spite of the power loss of a transceiving wave signal by amplifying variably the transceiving wave signal level between a base station and the mobile telephone terminal. CONSTITUTION: A signal level detection/control unit(20) and a wave signal variable amplification unit(30) are operated by the driving power of a power supply unit(10). The signal level detection/control unit(20) detects the level of a transceiving wave signal between a base station and the mobile telephone terminal, and outputs a variable gain signal to vary the detected signal level according to the comparison of the DC voltage of the detected signal level and the reference voltage. The wave signal variable amplification unit(30) amplifies variably the transmission wave signal of the base station to transmit to the mobile telephone terminal according to the variable gain signal from the signal level detection/control unit(20), and amplifies variably the transmission wave signal of the mobile telephone terminal to transmit to the base station.
