CC1120RHBT

RF Transceiver ICS Overview

The Texas Instruments CC1120RHBT is a high-performance sub-1 GHz wireless transceiver designed for narrowband systems. It operates within frequency ranges of 164 MHz to 192 MHz, 410 MHz to 480 MHz, and 820 MHz to 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, MSK, and OOK. It functions on a supply voltage between 2 V and 3.6 V, drawing 17 mA during reception and 45 mA during transmission. The transceiver delivers an output power of 16 dBm and achieves a sensitivity of -123 dBm. It utilizes an SPI interface and is housed in a VQFN-32 package.

RF Transceiver ICS Procurement Notes

Verify the specific suffix RHBT corresponds to the required tape-and-reel packaging configuration when ordering. Confirm that the operating temperature range meets the environmental requirements of the target application. Ensure compatibility with the host microcontroller's SPI interface timing specifications. Check for RoHS compliance status if restricted substances are a concern for the final product assembly.

RF Transceiver ICS Selection Notes

Select this component for applications requiring high sensitivity and robust performance in narrowband sub-1 GHz bands. Compare against the CC1121 variant if lower power consumption is prioritized over maximum RF performance. Evaluate the VQFN-32 package size constraints against the PCB layout requirements. Consider the supported modulation schemes to ensure alignment with the desired communication protocol standards.

RF Transceiver ICS Part Context

The CC1120RHBT belongs to the CC1120 family of high-performance RF transceivers from Texas Instruments. This series is engineered specifically for narrowband wireless applications where reliability and range are critical. The RHBT suffix indicates a specific reel-based packaging format intended for automated surface-mount assembly processes.

RF Transceiver ICS Replacement Considerations

CC1120RHBR is a pin-compatible alternative available in different packaging options. CC1121RHBT offers similar functionality with potentially different power characteristics. Verify electrical parameter equivalence before substituting these parts in existing designs.
