| 摘要 |
<p>The present invention relates to a transmission device of a portable terminal, which enables an amplifier to obtain amplification information directly from a processor and to perform amplification instead of obtaining the amplification information from the processor through a DC/DC converter when amplifying a transmission signal for a specific frequency band among a plurality of frequency bands supported by the portable terminal. The transmission device of a portable terminal includes: a processor module to generate a transmission signal; a first amplification module to amplify the transmission signal for a first frequency band among a plurality of frequency bands; a switching module to guide the amplified transmission signal to a signal path for the first frequency band; and a first antenna to transmit the transmission signal received through the signal path.</p> |
