Transmit-receive circuitry for an electronic device capable of wireless communication, the circuitry comprising: an antenna input/output, for coupling to an antenna; a transmit path, coupled to the antenna input/output, the transmit path comprising: a power amplifier, for receiving a transmission signal to be transmitted via the antenna; and a transformer; and a receive path, coupled to the antenna input/output, the receive path comprising: a low noise amplifier, for receiving a reception signal from the antenna. In a receive mode, the low noise amplifier is configured to receive reception signals via the antenna input/output, and the transmit path is connected to the antenna input/output such that the reception signals experience gain as a result of the transformer in the transmit path. |
