Compensation for a signal damping while transmitting transmission signals of a wireless mobile device

摘要

A circuit arrangement compensates for signal damping while transmitting transmission signals of a wireless mobile device. The circuit arrangement contains an adjustable signal level amplifying device which has a signal amplifier for amplifying the transmission signals with a signal amplification generated by the signal amplifier. The circuit further has an adjusting device for adjusting a resulting signal amplification, and a detector arrangement which detects whether a signal level of the transmission signal of the mobile device has exceeded an upper threshold and whether the signal level has reached a lower threshold. The detector arrangement causes the adjusting device to reduce the resulting signal amplification generated by the signal level amplifying device if the signal level has reached the upper threshold. The detector arrangement causes the adjusting device to reduce the resulting signal amplification generated by the signal level amplifying device if the signal level has fallen below the lower threshold.
