CC1121RHMR

RF Transceiver ICS Overview

The CC1121RHMR is a high-performance, low-power RF transceiver integrated with an MCU, designed for ISM bands below 1GHz. It operates within frequency ranges of 164–192MHz, 274–320MHz, 410–480MHz, and 820–960MHz. The device supports data rates up to 200kbps and delivers excellent receiver sensitivity, achieving -120dBm at 1.2kbps and -110dBm at 50kbps. It features a 16dBm power output and includes 4kB ROM and 256B RAM. Powered by a 2V to 3.6V supply, it utilizes a 32-VQFN package with a bare pad.

RF Transceiver ICS Feature Summary

• Integrates a microcontroller unit with the RF transceiver for enhanced system control.
• Provides exceptional receiver sensitivity for reliable long-range communication.
• Supports multiple modulation schemes including 2FSK, 4FSK, MSK, and OOK.
• Operates across four distinct sub-1GHz ISM frequency bands.

RF Transceiver ICS Applications

RF Transceiver ICS Procurement Notes

Verify component authenticity through authorized Texas Instruments distributors or certified partners. Confirm that the received part matches the specific RHMR suffix and 32-VQFN package details. Review the official datasheet for handling instructions regarding moisture sensitivity level 3 classification. Ensure compliance with RoHS standards as indicated in manufacturer documentation before integration into final products.

RF Transceiver ICS Selection Notes

Select this component when a combined RF and MCU solution is required for sub-1GHz applications. It is suitable for designs needing high sensitivity and moderate data throughput. Consider the 32-VQFN package constraints for PCB layout. Evaluate power consumption requirements against the specified receive and transmit current ranges to ensure battery life targets are met in portable devices.

RF Transceiver ICS Part Context

This part belongs to the CC112x family of high-performance low-power RF transceivers from Texas Instruments. The CC1121 variant specifically integrates an MCU, distinguishing it from standard transceiver models like the CC1120.
