发明名称 HIGH FREQUENCY MODULE AND COMMUNICATION DEVICE
摘要 <p>Provided is a high frequency module provided with a plurality of branching filters, wherein generation of IMD is suppressed. A high frequency module (20) is provided with first and second branching filters (22, 21), and a band rejection filter (23). The first and the second branching filters (22, 21) respectively have common terminals (22a, 21a), transmission filters (22d, 21d), and reception filters (22e, 21e). In the band rejection filter (23), a terminal (32) on the branching filter side is connected to the common terminal (22a) of the first branching filter (22). The band rejection filter (23) has a first passband, and a second passband and a rejection band, which are positioned adjacent to each other in the first passband. The band rejection filter (23) is configured such that the second passband includes the passbands of the transmission filter (22d) and the reception filter (22e) of the first branching filter (22), and that the rejection band includes the passband of the transmission filter (21d) of the second branching filter (21).</p>
