SiTune samples low power 5G RF transceiver
SiTune is sampling its IceWings programmable 5G RF transceiver built in the 22FDX FD-SOI process from Global Foundries

US chip designer SiTune is sampling a 5G RF transceiver silicon and reference board that it says has the lowest power available.

The IceWings transceiver includes support for 5G NR gNodeB, small cell, CPE, and User Equipment with 4 integrated transmitters and 4 integrated receivers that supports a wide range of standards with signal frequencies below 7.2GHz and enables mmWave applications by intermediate to baseband conversion.

SiTune is working with MixComm, being acquired by Sivers Semiconductor in Sweden, on a 5G mmWave reference design.

The wide-band low noise amplifiers and multi-band capability enable the low power consumption for TDD/FDD applications including cellular infrastructure designs as well as private networks and access points using the OpenRAN specification.

The  silicon is based on GlobalFoundries 22FDX silicon on insulator process for the lower static power consumption with digital and RF enhancements for 5G Sub-7GHz and mmWave infrastructure. With accelerated investment in the newly opened C-band, or n77/ n78/n79 as the world's most popular 5G band, the integrated low power programmable transceiver supports any band and various bandwidths.

"IceWings not only supports more than 300MHz 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," said Dr. Marzieh Veyseh CTO at SiTune. "All frequency bands below 6GHz as well as 6GHz to 7.2GHz are supported with excellent wide-bandwidth performance. We have been partnering with GF to fabricate IceWings based on their leading FDSOI solution, 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.  "The combination of SiTune's leading technology and GF's innovative solutions, will unlock a new wave of immersive user experiences and make industry transformation a reality."

"To be true beneficiaries of 5G, we need to navigate the market through all the multiplicities and complexities of 5G, intuitively and seamlessly.  IceWings™ uniquely addresses the pluralities of 5G in an elegant manner.  By collapsing multiple spectrums, multiple bands, and multiple protocols into a compact footprint that is efficient, intelligent, and low power, we can distill 5G into a simple construct, ideal for wireless infrastructure," said Hari Gangadharan, Head of Silicon Engineering of EdgeQ.

"5G's transformative power will be realized by the broad deployment of the infrastructure in the mid-band. This requires best-in-class RF transceivers, where IceWings™ is a clear technology leader with the highest integration at the lowest power dissipation," said Hossein Moiin, Operating partner at Cota Capital and former CTO of Nokia.
