SiTune Corp. has introduced a new power radio frequency (RF) transceiver silicon along with reference designs and software platform.

Called IceWings, the RF transceiver can be used by various products including 5G NR gNodeB, small cell, CPE and user equipment.

IceWings contains four integrated transmitters and four integrated receivers that support a wide range of standards with signal frequencies below 7.2 GHz and allows for millimeter wave (mmWave) applications by intermediate to baseband conversion.

The device includes wide-band low noise amplifiers and multi-band capability for high signal quality and low power consumption. The device also provides a diverse range of time division duplex/frequency division duplex (TDD/FDD) applications such as cellular infrastructure designs as well as private networks and access points.

The silicon will be built using GlobalFoundries' 22FDX platform for better performance with digital and RF enhancements for 5G sub-7 GHz and mmWave infrastructure.

"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," said Marzieh Veyseh CTO/CPO at SiTune. "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 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)."
