Abstract

A wireless transceiver includes: a switching amplifier having first, second and power ports; and a current provider. The current provider provides a current to the power port, and further provides an impedance to the power port such that an impedance of the switching amplifier at the second port matches an impedance of an antenna coupled to the second port. The switching amplifier simultaneously amplifies a transmit signal input received at the first port to generate an output signal at the second port for receipt by the antenna, and mixes a receive signal received at the second port from the antenna with the transmit signal input to generate, at the power port, another output signal having a frequency lower than that of the receive signal.

Dependent claims

A wireless transceiver comprising:

a switching amplifier having a first port, a second port that is used to be coupled to an antenna, and a power port;
and
a current provider coupled to said power port of said switching amplifier, providing a current to said switching amplifier, and further providing an impedance to said switching amplifier such that an impedance of said switching amplifier at said second port matches an impedance of the antenna;
said switching amplifier being for receiving a transmit signal input at the first port thereof, and being further for receiving a receive signal from the antenna at the second port thereof;
said switching amplifier simultaneously
amplifying the transmit signal input to generate a first output signal at said second port thereof for receipt by the antenna, and
mixing the receive signal with the transmit signal input to generate, at said power port thereof, a second output signal having a frequency lower than that of the receive signal.
