CC1121RHBR

The CC1121RHBR from Texas Instruments is a single-chip, high-performance, low-power wireless transceiver designed for Sub-1 GHz applications. It supports a broad range of frequency bands, including 136.7-160, 164-192, 205-240, 273.3-320, 410-480, and 820-960 MHz, making it suitable for various regional requirements.

This transceiver IC boasts excellent receiver sensitivity of -120 dBm at 1.2 kbps and -110 dBm at 50 kbps, along with a maximum transmit power of +16 dBm. It supports multiple modulation schemes such as GMSK, 2(G)FSK, 4(G)FSK, ASK, and OOK, and configurable data rates from 1.2 to 200 kbps. The device operates within a wide supply voltage range of 2.0 V to 3.6 V and features low current consumption in various modes, including a power-down current of 0.12 µA.

Packaged in a 5 mm x 5 mm VQFN (RHB) 32-pin package, the CC1121RHBR is designed for surface mounting. It includes features like separate 128-byte RX and TX FIFOs, advanced digital signal processing for improved sync detection, and support for integration with the CC1190 device for extended range. The device is suitable for systems targeting compliance with regulations such as ETSI EN 300 220 and FCC CFR47 Part 15.

Key electrical characteristics include a blocking performance of 86 dB at 10 MHz and adjacent channel selectivity of 60 dB. The operating temperature range is -40°C to 85°C. The CC1121RHBR is an ideal component for applications requiring robust and efficient wireless communication in the Sub-1 GHz spectrum.
