CC1125RHMT

RF Transceiver ICS Overview

The CC1125RHMT is an ultra-high performance RF narrowband transceiver from Texas Instruments, housed in a 32-VQFN package. It operates within frequency ranges of 164–192 MHz, 274–320 MHz, 410–480 MHz, and 820–960 MHz. The device supports data rates up to 200 kb/s with modulation formats including 2-FSK, 2-GFSK, 4-FSK, 4-GFSK, ASK, MSK, and OOK. Powered by a 2 V to 3.6 V supply, it delivers up to +16 dBm output power with 0.4 dB step resolution. Receive current is 17 mA, while transmit current reaches 47 mA. It functions between -40°C and +85°C via an SPI interface.

RF Transceiver ICS Procurement Notes

Verify the specific suffix RHMT against official Texas Instruments documentation to confirm package type and temperature range. Ensure compatibility with your system's voltage levels and SPI interface requirements. Cross-reference the datasheet for moisture sensitivity level and handling precautions during assembly. Confirm that the component meets RoHS compliance standards required for your manufacturing process.

RF Transceiver ICS Selection Notes

Select this component when high sensitivity and strong adjacent channel rejection are critical for narrowband operations. The programmable power amplifier allows optimization for range versus power consumption. Consider the 32-VQFN package for space-constrained designs requiring surface mount technology. Evaluate the supported modulation formats against your protocol stack requirements before finalizing the design.

RF Transceiver ICS Part Context

This part belongs to the CC1125 family of ultra-high performance RF transceivers. It shares core functionality with variants like CC1125RHBR but differs in packaging and potentially tape-and-reel specifications. The series is engineered for ISM band applications below 1 GHz, offering a balance of performance and power efficiency for industrial and commercial wireless solutions.

RF Transceiver ICS Replacement Considerations

Direct substitutes include other CC1125 variants such as CC1125RHBR or CC1125RHMR, provided the package footprint and electrical characteristics match the design requirements. Verify pin-to-pin compatibility and ensure that any alternative suffix does not alter the functional capabilities or operating temperature range defined in the original specification.
