Adaptive radio transceiver with an antenna matching circuit
First Claim
1. A method of wireless communications via at least one antenna of a wireless spread spectrum communications device, comprising:
- continuously coupling operatively, with a substantially constant impedance, at least one output of a transmitter of the wireless spread spectrum communications device to at least one input of a receiver of the wireless spread spectrum communications device through at least one coupling circuit of the wireless spread spectrum communications device, each coupling circuit comprising a first node and a second node;
operatively coupling a transmission signal to the at least one antenna via the at least one output of the transmitter;
operatively coupling one of the at least one output of the transmitter to one of the first node of the at least one coupling circuit;
operatively coupling a receive signal to the at least one input of the receiver via the at least one antenna; and
operatively coupling one of the at least one input of the receiver to one of the second node of the at least one coupling circuit.

Abstract
An exemplary embodiment of the present invention described and shown in the specification and drawings is a transceiver with a receiver, a transmitter, a local oscillator (LO) generator, a controller, and a self-testing unit. All of these components can be packaged for integration into a single IC including components such as filters and inductors. The controller for adaptive programming and calibration of the receiver, transmitter and LO generator. The self-testing unit generates is used to determine the gain, frequency characteristics, selectivity, noise floor, and distortion behavior of the receiver, transmitter and LO generator. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.
