A wideband up/down converter designed to operate in LEO environments with an on-board frequency synthesizer and low power consumption all in a credit-card-sized footprint. The module supports time-division up/down-conversion with 1GHz of instantaneous bandwidth and offers the ability to combine IF channels for further flexibility.

The CesiumAstro UDC-1AT1 includes a high-precision clock for LO generation; the module can provide this clock as a reference for other modules, or lock to an external system reference.

Use as a stand-alone up/down converter or combine with other CesiumAstro modules for a complete Ka-band communications solution.

The CesiumAstro UDC-1AT1 includes a fixed-frequency converter with integrated filters and protections, as well as a digital interface for telemetry in a credit-card-sized footprint.
