CC1125RHBR

RF Transceiver ICS Overview

The CC1125RHBR is an ultra-high performance RF narrowband transceiver manufactured by Texas Instruments. It operates within four frequency bands: 164–192 MHz, 274–320 MHz, 410–480 MHz, and 820–960 MHz. The device supports a maximum data rate of 200 kb/s with modulation formats including 2-FSK, 2-GFSK, 4-FSK, 4-GFSK, ASK, MSK, and OOK. It delivers up to +16 dBm output power and achieves a sensitivity of -129 dBm. Powered by a 2 V to 3.6 V supply, it draws 17 mA during reception and 47 mA during transmission. It features an SPI interface and is housed in a VQFN-32 package.

RF Transceiver ICS Feature Summary

• Supports multiband operation across sub-1 GHz ISM frequencies
• Delivers high transmit power with programmable steps down to 0.4 dB
• Integrates automatic power ramping for regulatory compliance
• Provides configurable data rates up to 200 kbps

RF Transceiver ICS Applications

• Industrial, Scientific, and Medical (ISM) wireless links
• Low-power sensor networks
• Wireless metering systems
• Alarm and security systems

RF Transceiver ICS Procurement Notes

Verify the specific suffix RHBR indicates tape and reel packaging when ordering. Confirm RoHS compliance status through the official datasheet or manufacturer documentation prior to integration. Ensure the design accounts for the specified operating temperature range of -40°C to +85°C. Validate that the VQFN-32 footprint matches the PCB layout requirements. Check for any recent product change notices regarding material or assembly updates.

RF Transceiver ICS Selection Notes

Select this component for applications requiring high sensitivity and strong output power in narrowband scenarios. It is suitable where low current consumption is critical alongside robust link budgets. Consider the SPI interface compatibility with the host microcontroller. Evaluate the need for multiple frequency band support versus single-band optimization. Compare against the CC1200 if higher data rates are required instead of extended range.

RF Transceiver ICS Part Context

The CC1125 belongs to the CC112x family of ultra-high performance RF transceivers from Texas Instruments. It is designed for sub-1 GHz applications requiring long-range communication capabilities. The device integrates a highly tunable radio front-end and a digital baseband processor. It serves as a solution for industrial and utility markets demanding reliable wireless connectivity.

RF Transceiver ICS Replacement Considerations

CC1121RHBR includes an integrated MCU core. CC1200RHBR offers higher data rates but lower output power. CC1175RHBR is a transmitter-only variant.
