摘要： In an apparatus and method for automatically detecting the presence of an external device in a port of a mobile terminal, the external device is automatically enabled without the additional operation of the mobile terminal when plugged into a jack. The mobile terminal may be safeguarded against severe damage being done thereto by mistakenly choosing options to enable an external device while an earphone/microphone set is plugged in the jack of a mobile terminal.

摘要： Disclosed is an apparatus and method for automatically detecting the presence of a strobo in an earphone jack port of a mobile terminal wherein the strobo is automatically enabled without the additional operation of the mobile terminal when the strobo is plugged into an earphone jack while a user uses a built-in digital camera. The present invention safeguards the mobile terminal against severe damage being done thereto by mistakenly choosing options to enable a strobo without knowing that an earphone/microphone set is plugged in the earphone jack of a mobile terminal.

摘要： A radio frequency transmission control apparatus for preventing an oscillation in a wideband wireless local loop terminal has a radio frequency transmitting unit for modulating a baseband transmitting signal to a WLL radio frequency band signal and transmitting the modulated signal via an antenna, and the radio frequency transmitting unit is divided into a radio frequency converting unit and a power amplifier unit in accordance with characteristics of each active element constituting the radio frequency transmitting unit. When a power is supplied to the radio frequency transmitting unit, the power is first supplied to the radio frequency converting unit so as to maintain the same at an operating state. After a predetermined time period has elapsed, the power is supplied to the power amplifier unit. When the radio frequency transmitting unit is cut off from a power, a cutoff of the power amplifier unit is performed prior to a cutoff of the radio frequency converting unit, to thereby prevent generation of an oscillation frequency in W-WLL terminal.
