Abstract
A transceiver includes a transmitter configured to transmit a first radio frequency signal, a switching device connected to the transmitter and configured to receive and transmit the first radio frequency signal to an antenna, a receiver connected to the switching device via an input and configured to receive a second radio frequency signal from the switching device, the receiver including an electrostatic discharge protection device connected to the input, and a biasing device connected to the electrostatic discharge protection device and configured to forward bias the electrostatic discharge protection device.
Claims20
A transceiver comprising:
- a transmitter configured to transmit a first radio frequency signal;
- a switching device connected to the transmitter and configured to receive and transmit the first radio frequency signal to an antenna;
- a receiver connected to the switching device via an input and configured to receive a second radio frequency signal from the switching device, the receiver including an electrostatic discharge protection device connected to the input;
- and
- a biasing device connected to the electrostatic discharge protection device and configured to forward bias the electrostatic discharge protection device.
A mobile communication device comprising:
- a transceiver including:
- a transmitter configured to transmit a first radio frequency signal;
- a switching device connected to the transmitter and configured to receive and transmit the first radio frequency signal to an antenna;
- a receiver connected to the switching device via an input and configured to receive a second radio frequency signal from the switching device, the receiver including an electrostatic discharge protection device connected to the input;
- and
- a biasing device connected to the electrostatic discharge protection device and configured to forward bias the electrostatic discharge protection device.
A transceiver comprising:
- means for transmitting a first radio frequency signal;
- means for switching the first radio frequency signal to an antenna;
- means for receiving a second radio frequency signal from the means for switching, the means for receiving including means for electrostatic discharge protection of the means for receiving;
- and
- means for forward biasing the means for electrostatic discharge protection.
A method for biasing a transceiver that transmits and receives radio frequency signals, the method comprising:
- transmitting from a transmitter a first radio frequency signal;
- leaking a second radio frequency signal, which is associated with the first radio frequency, to a receiver path, the receiver path including an electrostatic discharge protection device and other receiver circuitry;
- and
- forward biasing the electrostatic discharge protection device with a biasing device to prevent the second radio frequency signal from reaching the other receiver circuitry.
