ACTIVE PHASED ARRAY

ACTIVE PHASED ARRAY

CesiumAstro’s wideband Active Phased Array (APA1701-130), which includes the antenna elements, power and low-noise amplifiers, beamformer, and point-of-load power converters, provides electronic steering in a plug-and-play module. The APA’s low mass and low profile make it well-suited for space-constrained systems, such as LEO satellites, launch vehicles, and other airborne platforms. The wide steerability (+/- 60 degrees) with built-in control module allows for tracking without mechanical movements and low user elevation angles. The APA is constructed in 9 cm by 9 cm tiles, and each tile can act either as a standalone unit or a building block for a larger array.

APA operates in Ku-band with right-(RHCP) and or left-hand circular polarization (LHCP). When paired with Cesium’s SDR and frequency converter, the APA allows for plug-and-play communication system.

UP / DOWN CONVERTER

UDC-1AT1

Mechanical View

A wideband up/down converter designed to operate in Low Earth Orbit (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 Cesium 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 Cesium modules for a complete Ka-band communication solution.
