Abstract

Various aspects of the present disclosure provide an apparatus for wireless communication. The apparatus may include an integrated circuit, an antenna, and a module located adjacent to the antenna. The module may include at least one of a power amplifier or a low-noise amplifier. The power amplifier may be configured to amplify a signal received from the integrated circuit for transmission by the antenna. The low-noise amplifier may be configured to amplify a signal received from the antenna for reception by the integrated circuit. The module may be separate from the integrated circuit. A length of a feed line connecting the antenna and the module may be less than a length of a feed line connecting the module and the integrated circuit. The module may also include a switching mechanism configured to switch operation of the module between transmission and reception.
