AT1846S Description

Short technical summary and product information.

The AT1846S from Auctus Solutions Inc. is a highly integrated single-chip transceiver specifically designed for walkie-talkie applications. This CMOS transceiver simplifies design by requiring minimal external components and eliminating complex RF circuit design on the PCB.

Key electrical features include support for worldwide frequency bands from 134MHz to 520MHz, with selectable channel spacing of 12.5KHz or 25KHz. It boasts a digital signal processor for optimum voice quality and robust performance. The device includes an 8 dBm PA on-chip, digital auto frequency control (AFC), digital auto gain control (AGC), and selectable pre/de-emphasis. It operates within a supply voltage range of 3.3V to 4.8V and offers analog and digital volume control.

For enhanced functionality, the AT1846S integrates CTCSS/CDCSS generation and judgment, DTMF capabilities, and an auto RX/TX/SLEEP state switching feature. It provides 8 GPIOs for flexible interfacing and supports 3-wire, 4-wire, and I2C serial control bus interfaces. The transceiver is housed in a compact 5x5mm, 32-pin QFN package, suitable for surface mount applications.

This transceiver is ideal for applications requiring efficient voice and RF carrier translation, such as family radio services and professional walkie-talkies.
