SiTune 5G RF transceiver targets low power Sub-7-GHz
The IceWings™ RF transceiver is raising the bar with superior performance, lowest power consumption, and most frequency band coverage.

SiTune Corporation is sampling IceWings™ as the lowest power RF transceiver silicon along with reference designs and complete software platform to Tier-1 customers and partners worldwide. IceWings™ feature sets and versatile architecture will be leveraged by multiple global customers in various products including 5G NR gNodeB, small cell, CPE, and User Equipment.

IceWings™ is an innovative RF transceiver with 4 integrated transmitters and 4 integrated receivers that supports a wide range of standards with signal frequencies below 7.2 GHz and enables mmWave applications by intermediate to baseband conversion. This unique product with wide-band low noise amplifiers and one-of-a-kind multi-band capability offers the highest signal quality and the lowest power consumption in the industry. IceWings™ is enabling a diverse range of TDD/FDD applications including cellular infrastructure designs as well as private networks and access points. The new silicon is based on the GlobalFoundries® (GF®) 22FDX™ platform, providing superior performance with digital and RF enhancements for 5G Sub-7-GHz and mmWave infrastructure.

With accelerated investment in the newly opened C-band, or n77/ n78/n79 as the world's most popular 5G band, equipment manufacturers and network operators are looking for the best-in-class RF products supporting the wider available bandwidth in various frequencies. Contrary to traditional products with costly BOM that require multiple high-power chips, IceWings™ offers an integrated low power programmable transceiver for any band and various bandwidths.

"IceWings™ not only supports more than 300 MHz of bandwidth for multi-carrier applications in C-band, it's also the lowest power solution in the market enabling operation in the sweet spot of mid-band in terms of bandwidth and signal range," says Dr. Marzieh Veyseh SiTune CTO/CPO. "All frequency bands below 6 GHz as well as 6 GHz to 7.2 GHz are supported with excellent wide-bandwidth performance. We have been partnering with GF to fabricate IceWings™ based on their leading FDSOI platform, and we are currently sampling IceWings™ to a wide range of enterprise and telco customers including EdgeQ, targeting use cases from enhanced mobile broadband (eMBB) to critical IoT and ultra-reliable low-latency communications (URLLC)"

"GF has been helping customers overcome 5G complexity challenges and rollout pressures, while minimizing CAPEX and OPEX expenditures, through a combination of feature-rich solutions and specialized RF post-fab turnkey services that build on our decades of RF expertise," said Peter Rabbeni, vice president, wireless infrastructure, and SATCOM business line at GF.
