ThinKom introduces new Q / V-band phased array satellite tv for pc antennas for subsequent era constellations
HAWTHORNE, Calif. – ThinKom Solutions announced the development of a new phased array user terminal specifically designed to operate in the higher millimeter wave (MMW) frequency bands for evolving next generation communications satellites.
The new low-profile antenna, based on ThinKom’s patented VICTS (Variable Inclination Continuous Transverse Stub) technology, operates in the Q and V band frequencies (37.5-42.5 GHz and 47.2-51.4 GHz). These bands have been designated for adoption by major satellite operators in low, medium, geostationary and highly elliptical orbits (LEO, MEO, GEO and HEO).
“This new phased array development is timed to fully enable the upcoming frequency revolution that promises to unlock tremendous new bandwidth available at these higher MMW frequencies for next-generation LEO and MEO satellite constellations,” said Bill Milroy, Chairman and CTO of ThinKom Solutions. “And it uses our proven VICTS architecture to ensure that it delivers the efficiency, instant bandwidth, reliability, resilience, and overall availability that our customers have come to expect from ThinKom.”
Similar Q-band MMW antennas have already been built and tested by ThinKom for use in air and ground mobility in the Q-band.
The full duplex terminal from ThinKom is 75 cm square and less than 10 cm high, weighs less than 23 kg and requires less than 100 watts of primary power; and still offers the same functionality as two separate, stabilized parabolic antenna radome housings with a diameter of 50 cm.
Milroy noted the difficulty of making usable electronically scanned arrays (ESAs) that can operate in these higher MMW bands, particularly in terms of space efficiency, packaging, power density, thermal management, and cost. In contrast, ThinKom’s new antennas offer industry-leading spectral efficiency, low power consumption, high energy efficiency and low heat generation. They are offered in configurations for aeronautical and ground-based fixed and mobile applications.
