Title:
HYBRID FILTER, MULTIPLEXER, HIGH-FREQUENCY MODULE, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/123823
Kind Code:
A1
Abstract:
This hybrid filter (10) comprises: a module substrate (80) having a main surface (80a) and a main surface (80b) facing each other; elastic wave resonators (P1, P2) disposed on the module substrate (80); inductors (L1 to L3) disposed on the module substrate (80); and a capacitor (C3) disposed on the module substrate (80), wherein the passband of the hybrid filter (10) is larger than the resonance bandwidth of the elastic wave resonators (P1, P2), a first circuit element, which is one of the elastic wave resonators (P1, P2), the inductors (L1 to L3), and the capacitor (C3), is disposed on the main surface (80a), and a second circuit element, which is another one of the elastic wave resonators (P1, P2), the inductors (L1 to L3), and the capacitor (C3), is disposed on the main surface (80b).
