  • RADIO FREQUENCY SWITCH ELECTROSTATIC DISCHARGE PROTECTION CIRCUIT
    Publication number: 20100002345
    Abstract: An electrostatic discharge (ESD)-protected radio frequency (RF) transceiver switching circuit includes two or more switchable RF transmit and receive port circuits, a diode-based ESD-protection circuit, and a voltage-dividing circuit. The voltage-dividing circuit, which can be a switching circuit, minimizes the number of diode devices needed to protect against ESD by dividing the voltage at the antenna node down to a lower voltage across the diode devices.
