An article written by Junko Yoshida for EETIMES – STMicroelectronics, not among the “usual suspects” indulging in 5G chips, is nonetheless making its move into this nascent market.
ST’s approach to 5G opportunities is cautious but methodical. First up, it’s going to advance its collaboration with Macom (Lowell, Massachusetts) on GaN-on-silicon, focusing initially on the telecom base-station market. Separately, ST is also angling to develop solutions for repeaters and small cells, which are sorely needed in 5G mmWave networks.
The newly announced agreement with Macom calls for ST to expand its 150-mm GaN-on-silicon production capacity this year at fabs in Catania, Sicily, and possibly move to 200 mm as demand picks up. GaN-on-silicon — instead of the GaN-on-SiC promoted by competitors — will be critical for OEMs to build out a new generation of high-performance 5G networks, according to Macom. It can offer “better performance and cost,” and now that a deal with ST is in place, GaN-on-silicon can provide a “high-volume supply chain,” according to the company… Full article
