Abstract
Systems, methods, and devices to transmit and receive wireless signals are described.
Claims20
A transceiver comprising:
- logic configured to:
- generate a first transmission signal;
- generate a second transmission signal that is phase shifted with respect to the first transmission signal;
- send the first transmission signal to a power amplifier module;
- and
- send the second transmission signal to the power amplifier module.
3 more elements
A system comprising:
- a transceiver;
- a power amplifier module coupled to the transceiver, the power amplifier module comprising:
- a hybrid circuit coupled to an input port of the power amplifier module;
- a first power amplifier unit coupled to a first output port of the hybrid circuit;
- a second power amplifier unit coupled to a second output port of the hybrid circuit;
- a first duplex filter coupled to a first output port of the power amplifier module;
- a second duplex filter coupled to a second output port of the power amplifier module;
- a first antenna coupled to the first duplex filter;
- and
- a second antenna coupled to the second duplex filter.
7 more elements
A method comprising:
- generating a first transmission signal and a second transmission signal at a transceiver, wherein the second transmission signal is phase shifted with respect to the first transmission signal;
- forwarding the first transmission signal to a first antenna via a first duplex filter;
- and
- forwarding the second transmission signal to a second antenna via a second duplex filter.
