Abstract
A communication module includes: a first substrate having a first surface; a second substrate having a second surface, the second surface facing the first surface across an air gap; a first filter located on the first surface, a passband of the first filter being either one of a transmit band and a receive band of a first band, the first band being a frequency division duplex band; and a second filter located on the second surface, at least a part of the second filter overlapping with at least a part of the first filter in a stacking direction in which the first substrate and the second substrate are stacked, a passband of the second filter being at least one of a transmit band and a receive band of a second band, the second band differing from the first band.

A communication module comprising:
- a first substrate having a first surface;
- a second substrate having a second surface, the second surface facing the first surface across an air gap;
- a first filter located on the first surface, a passband of the first filter being either one of a transmit band and a receive band of a first band, the first band being a frequency division duplex band;
- and
- a second filter located on the second surface, at least a part of the second filter overlapping with at least a part of the first filter in a stacking direction in which the first substrate and the second substrate are stacked, a passband of the second filter being at least one of a transmit band and a receive band of a second band, the second band differing from the first band.
A communication module comprising:
- a first filter located on a first surface;
- and
- a second filter located on a second surface, the second surface facing the first surface across an air gap, at least a part of the second filter overlapping with at least a part of the first filter in a stacking direction in which the first surface and the second surface are stacked, the second filter being not used for communication at the same time as the first filter.
