Abstract
Abstract A transceiver of a dual-band radio is provided that selectively transmits and receives on either of a first frequency and a second frequency wherein the transceiver includes an integrated circuit having a power amplifier configured to amplify signals for transmission on a first frequency, and a low-noise amplifier configured to amplify signals received on the second frequency. The transceiver may further include a second integrated circuit having a power amplifier configured to amplify signals for transmission on a second frequency, and a low-noise amplifier configured to amplify signals received on the first frequency.
