InnoPhase Efficient 5G Small Cells for Inexpensive End Product Design

InnoPhase just announced the Hermes TWO digital radio device to provide more efficient cellular networks. The device incorporates the company’s radio architecture, providing greater system efficiency and performance. InnoPhase claims that it shatters existing levels of integration by incorporating many key radio components onto a single CMOS semiconductor die, including power amplifiers, Tx/Rx chains, digital signal processing with time/frequency conversions (FFT/iFFT), and system control. The result is a highly efficient system implementation for such cellular network radio units as enterprise small cells.

5G implementation for commercial and private networks will depend on cost. Purchase, installation, and operational costs must meet financial, performance, and efficiency targets for widespread adoption.

The “Digital-to-RF” radio architecture within Hermes TWO supports packetized O-RAN symbols over SERDES converted directly to amplified RF power. It incorporates 4G/5G Low-PHY functionality, including digital signal processing, advanced digital pre-distortion (DPD), and crest-factor reduction (CFR). A CMOS digital power amplifier (DPA) provides 3W peak / 500mW average transmit output power. The level of integration is an industry first.

The Hermes TWO devices will be designed into a 4T4R O-RAN 7.2a small cell Radio Development Kit (RDK) to expedite validation and customer product developments. Product samples will be available to lead customers and partners in 2Q2023. The first RDK focusing on 5G CBRS/C-Band is targeted for availability in mid-year 2023.
