Product details
Overview
CC1200RHBT from Texas Instruments is a fully integrated, single-chip RF transceiver optimized for wideband ISM/SRD applications in 164–190 MHz, 410–475 MHz, and 820–950 MHz bands. It delivers –123 dBm sensitivity at 1.2 kbps, +16 dBm programmable output power with 0.4-dB steps, and supports 2-FSK/4-GFSK/OOK modulations up to 1.25 Mbps - enabling long-range, low-power wireless sensor networks and smart metering systems.
For engineers reviewing the CC1200RHBT datasheet, CC1200RHBT pinout, CC1200RHBT application, or CC1200RHBT equivalent, this page provides verified technical context on its WaveMatch digital signal processing, hardware AES128 acceleration, eWOR timer, RX sniff mode (0.5 mA), and pin-compatibility with CC1120 - all critical for regulatory-compliant 802.15.4g, wireless M-Bus, and ETSI EN 300 220/FCC Part 15 system design.
Technical Context
The CC1200RHBT implements a fractional-N frequency synthesizer with configurable loop bandwidth (200–500 kHz), integrated 90-dB dynamic range ADCs for I/Q demodulation, and dual-path analog front-end with high-linearity LNA (IIP3 = –14 dBm) and high-efficiency PA. Its digital baseband includes dedicated packet handling logic supporting CRC-16/32, FEC, whitening, and auto-acknowledge.
WaveMatch enhances sync detection via advanced digital signal processing, while the enhanced Wake-On-Radio (eWOR) engine enables ultra-low-power receive polling with 0.5 μA retention current and configurable wake intervals. The device operates from 2.0–3.6 V and integrates all RF filters, eliminating external SAW/IF components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sensitivity | –123 dBm @ 1.2 kbps (433 MHz); enables reliable reception at extreme range in low-data-rate AMR/AMI deployments |
| Output Power | +16 dBm max (868/433 MHz, VDD = 3.6 V); sufficient for 1 km+ line-of-sight with standard antennas under ETSI limits |
| Data Rate | Up to 1.25 Mbps in packet mode; supports high-throughput firmware updates and dense sensor mesh backhaul |
| Modulation Support | 2-FSK, 4-GFSK, MSK, OOK; covers mandatory and optional modes for IEEE 802.15.4g and wireless M-Bus |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CC1120RHBT | Narrowband-optimized; superior phase noise (–114 dBc/Hz @ 10 kHz) and adjacent-channel rejection but lower max data rate (200 kbps) | Better suited for narrow-channel (12.5 kHz) legacy systems; less ideal for 802.15.4g wideband or high-throughput sensor mesh | Select CC1120RHBT when channel spacing ≤25 kHz and spectral purity dominates over data rate |
| SI4463-C2A-GMR | Higher TX efficiency (48 mA @ +20 dBm), integrated DC-DC converter, but no hardware AES and larger 4×4 mm QFN-20 package | Preferred for battery-critical designs needing >+17 dBm output; lacks native 802.15.4g packet handling features | Choose SI4463-C2A-GMR when extended range with external PA is required and security is handled externally |
Compared with CC1120RHBT and SI4463-C2A-GMR, the CC1200RHBT uniquely balances wideband data throughput (1.25 Mbps), regulatory-ready feature set (AES128, FEC, WaveMatch), and ultra-low RX Sniff current (0.5 mA), making it optimal for next-generation 802.15.4g and wireless M-Bus infrastructure.

FAQ
What frequency bands does the CC1200RHBT support?
The CC1200RHBT supports ISM/SRD bands at 164–190 MHz, 410–475 MHz, and 820–950 MHz, with documented performance validation for 169 MHz, 433 MHz, and 868/915/920 MHz. It also supports extended ranges including 137–158.3 MHz, 205–237.5 MHz, and 274–316.6 MHz - subject to TI confirmation and regulatory testing per band.
Does the CC1200RHBT require external RF filters?
No, the CC1200RHBT integrates all RF filters internally, eliminating the need for external SAW or IF filters. This reduces BOM cost and PCB area while maintaining ETSI EN 300 220 and FCC Part 15 spectral compliance across supported bands - confirmed in TI's SWRS123D datasheet Section 1.3.
How does the CC1200RHBT achieve ultra-low-power operation?
The CC1200RHBT achieves ultra-low-power operation through multiple hardware features: 0.12 µA power-down with retention, 0.5 mA RX Sniff Mode with configurable wake intervals, and an integrated 40-kHz auto-calibrated RC oscillator for eWOR timing. These features enable multi-year battery life in wireless sensor nodes without compromising RF performance.
Is the CC1200RHBT pin-compatible with other TI transceivers?
Yes, the CC1200RHBT is explicitly pin-compatible with the CC1120RHBT per TI's SWRS123D datasheet Section 1.1. This allows direct PCB layout reuse between narrowband (CC1120) and wideband (CC1200) designs, reducing development time and qualification effort for product families spanning both architectures.
What modulation schemes and data rates does the CC1200RHBT support?
The CC1200RHBT supports 2-FSK, 4-FSK, 2-GFSK, 4-GFSK, MSK, and OOK modulations, with data rates up to 1.25 Mbps in packet mode and 625 kbps in transparent mode. Real-world validated rates include 1.2 kbps (–123 dBm sensitivity) and 50 kbps (–109 dBm), meeting IEEE 802.15.4g mandatory and optional PHY requirements.
