Product details
Overview
RI-RFM-008B-00 from Texas Instruments is a 134.2 kHz low-frequency radio frequency power module designed as the reader-side driver in HDX/FSK RFID systems. It delivers high-power RF output, supports antenna resonance voltage up to 380 Vpeak, operates from 7–24 Vdc, and enables reader-to-antenna distances up to 120 meters via symmetrical twinax cable - deployed in vehicle identification and container tracking systems.
For engineers reviewing the RI-RFM-008B-00 datasheet, RI-RFM-008B-00 pinout, RI-RFM-008B-00 application, or RI-RFM-008B-00 equivalent, key selection criteria include its 134.2 kHz transmit frequency, HDX/FSK transponder compatibility, 7–24 Vdc supply range, –25°C to +70°C operating temperature, and support for remote antenna configurations up to 120 m.
Technical Context
The RI-RFM-008B-00 functions as the RF power source in a two-module architecture: it drives the RI-ACC-008B antenna tuning module, which forms the resonant LC circuit with external antennas (8–80 µH). It does not integrate antenna tuning or digital decoding - those are handled by the companion ACC module and host control unit.
It interfaces exclusively with TI's Series 2000 control modules (e.g., RI-CTL-MB2A or RI-CTL-MB6A) via dedicated power and signal connections, and relies on symmetrical twinax cabling to preserve signal integrity over extended distances without requiring local antenna-side power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Transmit Frequency | 134.2 kHz - precisely matches TI HDX/FSK transponder carrier, enabling reliable energization and bidirectional communication. |
| Power Supply Range | 7–24 Vdc, regulated - accommodates industrial power rails and allows flexible integration with RS232/RS422 control modules. |
| Operating Temperature | –25°C to +70°C - validated for use in outdoor access control and harsh industrial environments including waste management sites. |
| Max Antenna Distance | Up to 120 m - achieved using symmetrical twinax cable, eliminating need for local RF amplification at antenna site. |
| Antenna Resonance Voltage | Up to 380 Vpeak - enables strong magnetic field generation for reliable coupling with passive LF transponders at extended range. |
| Transponder Compatibility | 134.2 kHz HDX/FSK only - supports TI's proprietary high-data-rate and fast-response protocols, not ISO 11784/11785 FDX-B. |
Pinout & Package
Package: 83 mm × 93 mm × 44 mm metal enclosure (±1 mm), 160 g, designed for DIN-rail or panel mounting in industrial enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | DC Power Input | Accepts 7–24 Vdc regulated supply; internal regulation powers RF stage and interface logic. |
| GND | Signal & Power Ground | Common reference for power, control signals, and RF return path; requires low-impedance connection to system ground plane. |
| RF OUT | Differential RF Output | Drives RI-ACC-008B via symmetrical twinax; impedance-matched 100 Ω differential output for minimal EMI over long cable runs. |
| CTRL IN | Control Interface Input | Receives command/data signals from RI-CTL-MB2A or RI-CTL-MB6A; level-shifted for RS232/RS422 compatibility. |
Key Features
| Feature | Design Value |
|---|---|
| HDX Technology Integration | Enables high-data-rate, collision-resistant communication with TI 134.2 kHz transponders - critical for multi-tag vehicle identification. |
| Remote Antenna Architecture | Decouples RF power generation from antenna location, allowing installation of ruggedized antennas in inaccessible or hazardous zones (e.g., landfill gates). |
| Industrial Environmental Rating | Validated per IEC 68-2-30 (21 cycles, <97% non-condensing humidity) - ensures reliability in outdoor, high-moisture waste management deployments. |
| Modular System Interface | Designed exclusively for plug-and-play integration with TI Series 2000 control modules - eliminates custom firmware or protocol translation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LF RFID reader module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-RFM-008B-30 | Same electrical specs and mechanical footprint; differs only in packaging configuration (tape-and-reel vs. tray) and active status per TI's orderable device list. | No functional difference; intended for automated SMT assembly rather than manual or semi-automated integration. | Select RI-RFM-008B-30 for volume production with pick-and-place equipment; RI-RFM-008B-00 remains valid for prototyping and low-volume industrial builds. |
| RI-RFM-009B-00 | Successor model with identical 134.2 kHz operation but enhanced thermal management and updated MSL rating; shares same pinout and control interface. | Offers longer lifetime in continuous-duty applications (e.g., 24/7 container yards); backward-compatible with existing RI-ACC-008B and control modules. | Choose RI-RFM-009B-00 for new designs requiring extended operational life or compliance with newer moisture sensitivity requirements. |
Compared with RI-RFM-008B-30 and RI-RFM-009B-00, the RI-RFM-008B-00 provides identical RF performance and system integration but targets manual or small-batch deployment where tape-and-reel handling is unnecessary - making it optimal for field-upgrade kits and evaluation setups.

FAQ
What is the primary function of the RI-RFM-008B-00 in an RFID system?
The RI-RFM-008B-00 serves as the high-power RF driver module in Texas Instruments' Series 2000 remote antenna architecture. It generates and modulates the 134.2 kHz carrier signal to energize and communicate with HDX/FSK transponders. It does not perform digital decoding or antenna tuning - those functions are handled by the RI-ACC-008B tuning module and host control unit. The RI-RFM-008B-00 must be used in conjunction with these components to form a complete reader system.
Does the RI-RFM-008B-00 support ISO 11784/11785 FDX-B transponders?
No, the RI-RFM-008B-00 is designed exclusively for TI's proprietary 134.2 kHz HDX and FSK transponder protocols. It does not support ISO 11784/11785 FDX-B, nor is it compatible with EM4100, Hitag, or other third-party LF standards. Its modulation scheme, timing, and data framing are specific to TI's transponder family, and interoperability outside that ecosystem is not guaranteed.
What type of cable is required between the RI-RFM-008B-00 and the RI-ACC-008B?
A symmetrical shielded twinax cable is mandatory for connecting the RI-RFM-008B-00 to the RI-ACC-008B. This cable preserves differential signal integrity and minimizes radiated emissions over distances up to 120 meters. Standard coaxial or twisted-pair cables are not supported and will degrade RF performance, cause instability, or prevent resonance - as confirmed in TI's SCBS850 datasheet and application guidance for the Series 2000 platform.
Can the RI-RFM-008B-00 operate independently without a control module?
No, the RI-RFM-008B-00 cannot operate autonomously. It requires a TI Series 2000 control module (e.g., RI-CTL-MB2A or RI-CTL-MB6A) to provide command sequencing, data formatting, power regulation, and host interface (RS232/RS422/485). The RI-RFM-008B-00 has no onboard microcontroller, memory, or protocol stack - it functions solely as an analog RF power amplifier driven by external control logic.
Is the RI-RFM-008B-00 RoHS compliant?
TI's packaging documentation indicates "TBD" for Eco Plan on RI-RFM-008B-00, meaning the Pb-Free/RoHS conversion plan was not defined at time of publication. No RoHS exemption or Green status is assigned. Customers requiring RoHS compliance should verify current status directly with TI or select the actively supported RI-RFM-008B-30 or RI-RFM-009B-00 variants, which have updated environmental certifications documented in TI's product content portal.
