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.

SPACE

Out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space or airborne platforms.

One Ka-band tile with 64 receive and transmit elements and two steerable beams.

Shown here is an application of our Nightingale systems on a 12U satellite operating in low-earth orbit.

See how it works

Six Ku-band tiles, each with 64 receive and 64 transmit elements, provide two beams that are electronically steerable to ±60 degrees; the available EIRP is up to 43dBW. A single Ka-band tile provides the gateway link.
