<p>Provided is a multiband transmission module that can prevent losses caused by switching elements, amplify a plurality of types of transmission signals, and perform outputting with smaller losses. The transmission module (10) includes a power amplifier (11) and a multiband isolator (12). The output terminal of the power amplifier (11) is connected to the single input terminal of the multiband isolator (12). The multiband isolator (12) includes a separate isolator (120L) for low frequency use and a separate isolator (120H) for high frequency use. The respective input terminals of the separate isolators (120L, 120H) are connected to the single input terminal of the multiband isolator (12). The respective output terminals of the separate isolators (120L, 120H) are connected, respectively, to a low-frequency-side output terminal and a high-frequency-side output terminal of the multiband isolator (12).</p> |
