Arralis launches K- and Ka-band analog bare die phase shifters
Arralis Technologies of Limerick, Ireland – which has a design center in Belfast and manufactures RF, microwave and millimeter-wave devices, modules and antennas up to and beyond 110GHz (the W-band) for aerospace/satellite and security markets – says that its K- and Ka-band analog bare die phase shifters are now in stock and available to order. Operating at 17-21GHz or 25-33GHz, the phase shifters enable up to 350º and >360º smooth phase variation across the band, respectively.
Arralis’ analog phase shifters are an alternative to digital phase shifters where any required phase delay is achievable, with the phase set by varying the control voltage in the range of -0.5V to 0.7V. This smooth phase variation is vitally important for the development of beam-steering antenna systems, says the firm.
The phase shifters have several key applications, including the following: frequency translation; beam-steering antenna; phased arrays; 5G networks; satellite downlinks; Internet of Things (IoT); and security.
“Electronically steerable antennas are becoming an ever-increasing necessity for the next generation of LEO [low Earth orbit] satellite constellations,” says engineer Dr Geoffrey Barigye. “These antenna have the ability to simultaneously steer multiple beams and allow beams to be rapidly re-positioned at speeds that are not possible with mechanically steered antenna,” he adds. “To help antenna designers to achieve this, Arralis have launched our new K & Ka-band phase shifters.”
