    摘要: Provided is a mobile transmitter and a transmitting method thereof. The mobile transmitter includes a transmission circuit and a control circuit. The transmission circuit selectively operates as a polar transmitter or a direct-conversion transmitter. The control circuit controls an operation of the transmission circuit based on the level of an output signal. The mobile transmitter operates as a direct-conversion transmitter using a linear power amplifier with a high dynamic range when it transmits a low-power signal. Also, the mobile transmitter operates as a polar transmitter using a switching power amplifier with a high power efficiency when it transmits a medium-power or high-power signal. Thus, the mobile transmitter according to the present invention can provide both the high power efficiency (i.e., the advantage of the switching power amplifier) and the high dynamic range (i.e., the advantage of the linear power amplifier). Consequently, it possible to increase the battery lifetime of a personal portable communication terminal and also to implement to a compound terminal that can satisfy a variety of communication standards with a high dynamic range.

    摘要: A display device having a cable card is provided wherein the cable card stores firmware, an interface that receives homing information from a service provider, an update part that updates the cable card firmware according to the homing information, a storage part that stores node information about at least one corresponding node, a message generator that generates a message indicating an update of the firmware of the cable card, and a communication part that transmits the message to the at least one corresponding node. The corresponding node information may be a phone number and the communication part can access a short messenger service center to transmit an SMS text message to the corresponding node. Accordingly, a user can be easily aware of the firmware update.
