Abstract
System and methods are provided for processing time-division signals and frequency-division signals using a multi-mode transceiver. The example system includes a power amplifier, a switching component, and a duplexer. The power amplifier is configured to receive a first time-division signal from the transceiver and to generate an amplified time-division signal based on the first time-division signal if the transceiver is in a time-division mode. The power amplifier is further configured to receive a first frequency-division signal from the transceiver and to generate an amplified frequency-division signal based on the first frequency-division signal if the transceiver is in a frequency-division mode. The switching component is configured to receive the amplified time-division signal from the power amplifier, and to output the amplified time-division signal for transmission. The duplexer configured to receive the amplified frequency-division signal from the switching component, and to output a transmission signal for transmission.
