Tune-up procedure of Transmitting Power with UTD

Adjustment of the transmitting power in UTD is carrying out the memory of the voltage of TX
AGC Amp which has decided for the transmitting output from below Minimum Transmit Power
(-20dBm) to more than Maximum Transmit Power (+26 dBm) to EEPROM as a transmitting DAC
value table. The temperature sensor also builds in UTD so that a changed part in temperature and
frequency can also be compensated. Including a changed part of temperature and frequency, it is
designed so that UT’s maximum power tolerance may become below +/- 3 dB.
