Abstract:
1. A wireless communications device with at least one antenna, comprising: a wireless transmitter of a wireless transceiver; a wireless receiver of the wireless transceiver; and at least one coupling circuit, wherein the at least one coupling circuit continuously and operatively couples, with a substantially constant impedance, at least one output of the wireless transmitter to at least one input of the wireless receiver, wherein the at least one coupling circuit comprises at least one first node and at least one second node, wherein the at least one output of the wireless transmitter operatively couples a transmission signal to the at least one antenna, wherein one of the at least one output of the wireless transmitter is operatively coupled to one of the at least one first node of the at least one coupling circuit, wherein the at least one input of the wireless receiver operatively couples a receive signal from the at least one antenna, wherein one of the at least one input of the wireless receiver is operatively coupled to one of the at least one second node of the at least one coupling circuit, wherein the wireless communications device supports spread spectrum modulation and supports wireless radio frequency communications, wherein the wireless communications device employs CMOS technology, and wherein the wireless transmitter and the wireless receiver are integrated on an integrated circuit chip.
