Arctic Semiconductor recently launched its SilverWings low-power all-in-one RF transceiver. Claimed as the industry’s first 4×4 low-power transceiver, the new device offers multi-stage up and down conversion from digital to RF and RF to digital for programmable and flexible system designs, tailored around the operating frequency, bandwidth and required specifications for optimal performance. The quad-channel transceiver supports 5G bands operating from 600 MHz up to 7.2 GHz.

The new chip leverages Arctic’s low-power architecture and expertise in both analog and digital design. SilverWings integrates high-performance analog capabilities with high-bandwidth digital features, incorporating unique digital-IF and high-IF conversion methodologies to improve performance and reduce costs.
The all-in-one capability refers to the transceiver’s suite of functionalities required for full up conversion and down conversion. The receiver end features an RF gain stage, facilitating ultra-fast automatic gain control (AGC) to counter interference. Digital pre-distortion (DPD) is incorporated on the transmit side to mitigate external power amplifier non-linearity. It also integrates DDC and DUC to support multiple intra-band aggregation.
In addition, the unique digital-IF conversion methodology eliminates the need for software calibration steps aimed at compensating for IQ imbalance and LO leakage. By eliminating the need for calibration, it saves significant cost during the development and production stages, the company said.
Another key feature is its ultra-low-power consumption. The SilverWings transceiver offers a more than 60 percent reduction in power consumption, compared to equivalent offerings in the market, according to the company, while also integrating RF gain with gain control within both the receive and transmit paths.
The SilverWings transceiver is available now. The device can be used in a range of applications, including wireless radios, satellite communication, repeaters, fixed-wireless access devices, user equipment, medical devices and instrumentation.
