Title:
HIGH-FREQUENCY MODULE
Document Type and Number:
WIPO Patent Application WO/2016/010063
Kind Code:
A1
Abstract:
The present invention improves isolation characteristics between transmission and reception terminals of a high-frequency module that uses transmission/reception signals of multiple different frequency bands. This high-frequency module (1a) is equipped with: a circuit board (2) having a rectangular shape in a plan view; a first branching filter (5a) for separating a transmission signal and a reception signal of a Band17 frequency band from each other; and a second branching filter (5b) for separating a transmission signal and a reception signal of a Band4 frequency band from each other, the reception-side frequency band of Band4 partially overlapping with the third-harmonic frequency band of the Band17 transmission signals. The first branching filter (5a) is disposed in proximity to a predetermined side of one main surface of the circuit board (2), and the second branching filter (5b) is disposed in proximity to the opposite side facing the predetermined side. In addition, lead-out wiring from a first transmission terminal (Tx1) of the first branching filter (5a) and lead-out wiring from a second reception terminal (Rx2) of the second branching filter (5b) are drawn out in directions away from each other.
