ABSTRACT:
In the portable telephone of the present invention, a transmission power upper limit value (STEPLIM) in accordance with temperature (T) is found (S1, S2), whether the transmission power set value (STEPn) of the next slot exceeds the upper limit (STEPLIM) or not is determined (S3, S4), and when it does not exceed, a control signal value (Vc) in accordance with the transmission power set value (STEPn) is applied to a variable gain block (11, 13) (S5, S7). When it exceeds the upper limit, a control signal value (Vc) in accordance with the transmission power upper limit value (STEPLIM) is applied to the variable gain block (11, 13) (S6, S7).
