摘要
An RF communications system includes a transmit node for transmitting an RF information signal and a receive node for receiving the transmitted RF information signal. The receive node includes a passive mixer coupled to an amplifier for producing an IF or baseband differential mixer output signal as a function of a LO drive signal. The passive mixer having a first plurality of transistors of a first polarity type arranged in a ring configuration and a second plurality of transistors of a second polarity type, wherein each of second plurality of transistors is coupled to one of said first plurality of transistors.
