US Patent 11979176 Configurable modem architecture for satellite communications

In some implementations, a communication device, includes a printed circuit board comprising conductors routed to support a plurality of different configurations of modulation and/or demodulation functionality. The printed circuit board can have multiple analog output interfaces and one or more analog input interfaces, multiple digital network interfaces, and sockets for components including a controller, multiple processors, digital-to-analog converters (DACs), and an analog-to-digital converter (ADC). Various processor sockets are interconnected to support the processors in different sockets selectively being used for different functions, e.g., as a modulator, burst processor, channelizer, etc.
