Abstract
A radio-frequency module includes a first transmitter-and-receiver that transmits and receives a signal in a first band, and a second transmitter-and-receiver that transmits and receives a signal in a second band higher than the first band. The first transmitter-and-receiver includes a first amplifier circuit and a first separator circuit and the second transmitter-and-receiver includes a second amplifier circuit and a second separator circuit. The first separator is located on a substrate between the first amplifier circuit and the second separator circuit, such that the first separator circuit is spatially interposed between the first amplifier circuit and the second separator circuit.
Claims19
A radio-frequency module comprising:
- a first transmitter-and-receiver that transmits a first transmitting signal and receives a first received signal in a first band;
- and
- a second transmitter-and-receiver that transmits a second transmitting signal and receives a second received signal in a second band higher than the first band;
- wherein
- the first transmitter-and-receiver and the second transmitter-and-receiver are mounted on a substrate;
- the first transmitter-and-receiver includes:
- a first antenna terminal connected to a first antenna;
- a first receive terminal connected to a first receive circuit;
- a first amplifier circuit that amplifies the first transmitting signal;
- and
- a first separator circuit that causes the first transmitting signal in the first band amplified by the first amplifier circuit to pass through the first separator circuit and transmits the first transmitting signal to the first antenna terminal and that causes the first received signal in the first band input from the first antenna terminal to pass through the first separator circuit and transmits the first received signal to the first receive terminal;
- the second transmitter-and-receiver includes:
- a second antenna terminal connected to a second antenna;
- a second receive terminal connected to a second receive circuit;
- a second amplifier circuit that amplifies the second transmitting signal;
- and
- a second separator circuit that causes the second transmitting signal in the second band amplified by the second amplifier circuit to pass through the second separator circuit and transmits the second transmitting signal to the second antenna terminal and that causes the second received signal in the second band input from the second antenna terminal to pass through the second separator circuit and transmits the second received signal to the second receive terminal;
- and
- the first separator circuit is located on the substrate between the first amplifier circuit and the second separator circuit.
