<p>Reception levels are measured in respective branches to compare the results of the measurements with one another to select the result of the measurement of a maximum reception level which is the highest reception level. The gains of variable gain amplifiers (6. 7) of all the branches including variable gain amplifiers (6, 7) included in a branch corresponding to the maximum reception level are adjusted to the same value such that output levels of the variable gain amplifiers (6, 7) are set to a preset target level.</p> |
