Patent ID: 7865149

Claim:
An integrated circuit transceiver, comprising: baseband processor for generating outgoing data and for processing ingoing data; analog front end for producing an outgoing RF signal from the outgoing data and for producing the ingoing data from a received ingoing RF signal; a power amplifier operably coupled to receive the outgoing RF signal to produce a power amplified outgoing RF signal; a radio frequency port for transmitting the power amplified outgoing RF signal and for receiving the ingoing RF signal; an on chip CMOS transmit-receive module operably coupled between the power amplifier and antenna on a transmit path and between the RF front end and the radio frequency port on a receive path; logic for producing a transmit-receive mode indication to the transmit-receive module to prompt the transmit-receive module to be configured in to a corresponding transmit or receive mode, wherein the transmit-receive module, based upon the mode indication, generates first and second bias signals to first and second wells formed about a MOSFET switch to create reverse biased junction across the boundary between the first and second wells and between the second well and one of a third well or substrate having a common boundary with the second well; and wherein the transmit-receive module further comprises switching circuitry for: during the transmit mode, closing a connection between the power amplifier and the antenna and for creating a high impedance circuit between the analog front end receive path and the radio frequency port; and during the receive mode, opening the connection between the power amplifier and the radio frequency port and for creating a low impedance circuit between the analog front end receive path and the radio frequency port.
