A modular satellite transceiver is provided according to some embodiments of the disclosure. The modular transceiver may include an RF module and a back end module. The RF module may operate in a first band, and may include, for example, one or more antennas, an RF front end module, an up converter, a down converter, an analog-to-digital converter, and a digital-to-analog converter. The back end module may include various digital processing components and/or modules. The RF module may be removably coupled with the back end module such that the RF module may be replaced with another RF module operating in a second band. During transmission the back end module may provide at least one digital signal to the RF module; and during reception the RF module provides at least one digital signal to the back end module.
