Abstract
Disclosed herein are various examples of architectures, circuits, devices and methods that provide wireless communication systems that can switch between switch combining and simplex operating modes. The switch combining modes utilize switching to dynamically route transmit and receive signals from a first antenna while the simplex operating modes route transmit signals to the first antenna and route receive signals from a second antenna. A controller is configured to control a duplexer to switch between the switch combining and the simplex operating modes.
Claims20
A communications system comprising:
- a duplexer having a transmit port as input for a transmit signal, a receive port as output for a receive signal, a first antenna port, and a second antenna port, the duplexer configured to route the transmit signal from the transmit port to the first antenna port or to the second antenna port based on an antenna select signal, and to route the receive signal to the receive port from the first antenna port or from the second antenna port based on the antenna select signal;
- and
- a controller configured to provide the antenna select signal to the duplexer and to switch between a switch combining operating mode that causes the duplexer to route the transmit signal from the transmit port to the first antenna port and to route the receive signal from the first antenna port to the receive port, and a simplex operating mode that causes the duplexer to route the transmit signal from the transmit port to the first antenna port and to route the receive signal from the second antenna port to the receive port.
A radio-frequency (RF) module comprising:
- a packaging substrate configured to receive a plurality of components;
- and
- a communications system implemented on the packaging substrate, the communications system including a duplexer having a transmit port as input for a transmit signal, a receive port as output for a receive signal, a first antenna port, and a second antenna port, the duplexer configured to route the transmit signal from the transmit port to the first antenna port or to the second antenna port based on an antenna select signal, and to route the receive signal to the receive port from the first antenna port or from the second antenna port based on the antenna select signal;
- and the communications system including a controller configured to provide the antenna select signal to the duplexer and to switch between a switch combining operating mode that causes the duplexer to route the transmit signal from the transmit port to the first antenna port and to route the receive signal from the first antenna port to the receive port, and a simplex operating mode that causes the duplexer to route the transmit signal from the transmit port to the first antenna port and to route the receive signal from the second antenna port to the receive port.

A wireless device comprising:
- a transceiver configured to generate a transmit radio-frequency (RF) signal and receive a receive RF signal;
- a plurality of antennas;
- and
- a front-end module (FEM) in communication with the first antenna and the second antenna, the FEM including a packaging substrate configured to receive a plurality of components, the FEM further including a communications system implemented on the packaging substrate, the communications system including a duplexer having a transmit port as input for a transmit signal, a receive port as output for a receive signal, a first antenna port, and a second antenna port, the duplexer configured to route the transmit signal from the transmit port to the first antenna port or to the second antenna port based on an antenna select signal, and to route the receive signal to the receive port from the first antenna port or from the second antenna port based on the antenna select signal;
- and the communications system including a controller configured to provide the antenna select signal to the duplexer and to switch between a switch combining operating mode that causes the duplexer to route the transmit signal from the transmit port to the first antenna port and to route the receive signal from the first antenna port to the receive port, and a simplex operating mode that causes the duplexer to route the transmit signal from the transmit port to the first antenna port and to route the receive signal from the second antenna port to the receive port.
