ADAPTIVE MODE OPTIMIZER AND MODE SHIFTER
First Claim
1. A mode shifter circuit comprising:
- an input port configured to receive a signal from an antenna port of a radio frequency (RF) transceiver;
a port signal analyzer configured to perform operations comprising;
determining whether a power measurement of the transceiver signal exceeds a threshold; and
issuing a transmit command signal to a signal switch to connect the input port to a transmit path when the power measurement exceeds the threshold,wherein the transmit path comprises a transmit signal processor configured to perform operations comprising;
shifting the transceiver signal to a shifted signal band, wherein the shifted signal band is lower or higher that a native frequency band of the transceiver, andcommunicating the shifted transceiver signal to at least one antenna for transmission.

Abstract
A mode shifter connects via an input port to an antenna port of a transceiver. A port signal analyzer monitors the signal at the input port and informs a signal switch whether the signal power exceeds a threshold value. When the signal power does not exceed the threshold value, the signal switch connects the input port (and consequently the antenna port of the transceiver) to a receive path comprising a receive signal processor, an antenna selection processor, and an antenna port. When the signal exceeds the threshold value, the signal switch connects the input port (and consequently the antenna port of the transceiver) to a transmit path comprising a transmit signal processor, the antenna selection processor, and an antenna port.
