Modular satellite transceiver
First Claim
1. A modular satellite transceiver comprising:
- an RF module operating in a first band, the RF module including one or more antennas, an RF front end module, a band converter, an analog-to-digital converter, and a digital-to-analog converter; and
a back end module that includes a digital processing module;
wherein the RF module is removably coupled with the back end module such that the RF module may be replaced with another RF module operating in a second band different from the first band;
wherein during transmission the back end module is configured to provide at least one digital representation of a modulated analog transmit signal to the RF module for digital-to-analog conversion and transmission; and
wherein during reception the RF module is configured to analog-to-digital convert at least one analog receive signal into at least one digital representation of a modulated analog receive signal, and provide the at least one digital representation of the modulated analog receive signal to the back end module for demodulation.

Abstract
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.
