Abstract
Some demonstrative embodiments include devices, systems and/or methods of selectively connecting between a transmit chain and an antenna. For example, a device may include a transmit chain and a non-active connector module configured to electrically connect the transmit chain to at least one antenna when the transmit chain generates a wireless communication signal, and to electrically disconnect the antenna from the transmit chain when a wireless communication signal is received via the antenna.
Claims18
A wireless communication device comprising:
- a transmit chain including a power amplifier;
- a non-active connector module configured to electrically connect the transmit chain to at least one antenna when the transmit chain generates an outgoing wireless communication signal, and to electrically disconnect the antenna from the transmit chain when an incoming wireless communication signal is received via the antenna, said antenna is directly connected to a receive chain;
- and
- a switchable connector to electrically connect the power amplifier to a supply voltage when the outgoing wireless communication signal is transmitted by the transmit chain, and to electrically disconnect the power amplifier from the supply voltage when the incoming wireless communication signal is received via the antenna.

A wireless communication system comprising:
- a wireless communication device including:
- at least one antenna directly connected to a receive chain;
- at least one transmit chain including at least one power amplifier;
- and
- a switchable connector to electrically connect the power amplifier to a supply voltage when the transmit chain is to transmit an outgoing wireless communication signal via the antenna, and to electrically disconnect the power amplifier from the supply voltage when an incoming wireless communication signal is received via the antenna.
2 more elements
A method comprising:
- activating a power amplifier of a transmit chain to amplify an outgoing wireless communication signal to be transmitted via at least one antenna, which is connected to the transmit chain, said antenna is directly connected to a receive chain;
- electrically connecting the power amplifier to a supply voltage when the outgoing wireless communication signal is transmitted via the antenna;
- and
- when an incoming wireless communication signal is received via the antenna, grounding the power amplifier and disconnecting the power amplifier from the supply voltage.
