Aethertek will be participating in the upcoming 2022 IMS (International Microwave Symposium) in Denver, USA. They will be showcasing their Open RAN RU, mmWave AiM (Antenna-in-Module) and OTA test solutions supporting FR1 and FR2 mmWave bands at a workshop that they will be conducting during the event.
Aethertek are accelerating FR1 & FR2 frequency bands technology development and applications in the global market with their mmWave product offering. Their offering includes:
Open RAN Radio Unit
Aethertek’s O-RU supports FR1 and FR2 mmWave frequency bands, and it is developed according to ORAN standard Option 7.2, using the eCPRI interface to connect with DU. In addition to the built-in FR1 antenna, it is also integrated with Aethertek’s mmWave module, IRIS to achieve ultra-high-speed transmission with dual-polarization and 400 MHz of bandwidth. Through this seminar, they hope to cooperate with more O-RAN Alliance members with a focus on system integration.
Phased Array Antenna
IRIS is a highly integrated phased array antenna module (AiM, Antenna in Module), which combines a beamforming IC with a 64-element (8x8) antenna array. It performs precise calibration and optimization for each antenna element. To meet the requirements of mmWave high directivity performance, Aethertek’s IRIS provides excellent output power, outstanding directivity accuracy and exceptional transmission quality in the FR2 bands of n257 and n261. Not only does IRIS effectively diminish the difficulty for existing FR1 manufacturers to develop FR2 products, but it also helps design FR2 related products in a more economical and efficient way with the IRIS module.
OTA Test Solution
Aethertek provides a series of UE test solutions for customers who are look for economical OTA testing solutions. In addition to the common FR1 OTA test, users are allowed to extend the traditional FR1 test range to FR2 mmWave frequency with the integration of Aethertek’s RF up down converter, makes it more cost-effective to perform mmWave OTA testing in production.
