Overview
The CC1020RSS, produced by Texas Instruments, is a true single-chip UHF RF transceiver designed for very low-power and very low-voltage wireless applications. This device is primarily intended for use in the ISM (Industrial, Scientific, and Medical) and SRD (Short Range Device) frequency bands, covering frequencies from 402 MHz to 470 MHz and 804 MHz to 930 MHz. It is particularly suited for narrow-band systems with channel spacing of 12.5 or 25 kHz, complying with standards such as ARIB STD-T67 and EN 300 220.
