Abstract:
Disclosed are embodiments of a transceiver front-end configured for a reduced noise figure (NF). Each of the embodiments includes an antenna, a transmitter branch and a receiver branch all connected to an input/output pad. The transmitter branch is coupled to the input/output pad (and thereby the antenna) by an impedance transformer. Only the receiver branch is selectively electrically connected to the input/output pad (and thereby the antenna) by a switch. A common matching network between the input/output pad and the switch provides both impedance matching and electrostatic discharge protection for the switch and the low noise amplifier, thereby reducing NF. Specific embodiments are disclosed for integration into specific technologies (e.g., fully depleted silicon-on-insulator (FDSOI) technology and fin-type field effect transistor (finFET) technology).
