Two 60-GHz V-band transceivers, the ST60A3H0 and ST60A3H1 from ST, offer short-range cable-free connectivity at up to 480 Mbps. Operating in half-duplex mode, these compact devices enable embedded USB2 (eUSB2), I2C, SPI, UART, and GPIO RF tunneling.

The ST60A3H0 and ST60A3H1 can be used in personal electronics like digital cameras, wearables, portable hard drives, and small gaming terminals. They also afford data transfer in industrial applications, such as rotating machinery. As cost-effective cable replacements, the transceivers allow designers to create products with slim, aperture-free cases.
Self-discovery with instant mating eliminates pairing, while low power consumption preserves battery runtime. The parts consume 130 mW in eUSB Rx/Tx mode and 90 mW in UART, GPIO, and I2C modes. Shutdown mode reduces power consumption to just 23 µW.
Housed in VFBGA packages, the ST60A3H0 connects to an external antenna, while the ST60A3H1 has an integrated antenna. Samples of the transceivers are available now and cost $5. Detailed technical data, evaluation kits, and production pricing are subject to a non-disclosure agreement.
