Product details
Overview
RI-MOD-TX8A-00 from Texas Instruments is a 4-channel TX/RX RF multiplexer module for 134.2 kHz RFID systems, enabling dynamic selection of one active antenna channel among four via two digital control inputs (CS_A/CS_B), with 10–24 VDC supply, 350 Vpeak antenna resonance voltage tolerance, and operation from –25°C to +70°C.
For engineers reviewing the RI-MOD-TX8A-00 datasheet, RI-MOD-TX8A-00 pinout, RI-MOD-TX8A-00 application, or RI-MOD-TX8A-00 equivalent, key selection considerations include RF channel switching logic, antenna voltage headroom, compatibility with RI-RFM-008B and RI-ACC-008B, and CE/FCC compliance for industrial RFID deployment.
Technical Context
The RI-MOD-TX8A-00 operates as a passive RF signal routing device-not an active transceiver-switching 134.2 kHz transmit/receive paths between a single Remote Antenna RF Module (RI-RFM-008B) and up to four antennas via a Remote Antenna Tuning Board (RI-ACC-008B). Channel selection uses TTL-compatible CS_A and CS_B inputs with binary encoding (00–11).
It supports symmetrical twin-ax shielded cabling between module and tuning board, imposes ≤4 Ω additional resistance per channel, and maintains RF integrity under humidity cycling (IEC 68-2-30, 21 cycles, <97% non-condensing). No internal amplification or signal conditioning is provided.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency | 134.2 kHz - matches ISO/IEC 18000-2 and EM4100/EM4200 tag protocols; fixed-frequency operation only. |
| Supply Voltage | 10–24 VDC - powers internal logic and relay drivers; no regulation or backup required. |
| Antenna Voltage Rating | Max. 350 Vpeak - defines safe RF voltage swing at antenna terminals during high-Q resonance. |
| Channel Resistance | ≤4 Ω per channel - limits insertion loss and heating in high-current 134 kHz TX bursts. |
| Operating Temp. | –25°C to +70°C - validated for industrial enclosure mounting without forced cooling. |
| Approvals | CE, FCC - confirms electromagnetic compatibility for deployment in EU and US industrial environments. |

FAQ
What is the function of RI-MOD-TX8A-00 in a 134.2 kHz RFID system?
The RI-MOD-TX8A-00 functions as a 4-channel RF multiplexer that routes transmit and receive signals between a single RI-RFM-008B RF module and up to four antennas. It does not generate or decode RF signals-its role is purely passive RF path selection via digital control inputs, enabling spatial coverage expansion without multiple RF modules. RI-MOD-TX8A-00 integrates no active RF components.
Which control signals are used to select channels on RI-MOD-TX8A-00?
RI-MOD-TX8A-00 uses two TTL-compatible digital inputs-CS_A and CS_B-to select one of four antenna channels using binary encoding (00 = Ch1, 01 = Ch2, 10 = Ch3, 11 = Ch4). These signals interface directly with a microcontroller GPIO or FPGA output; no level-shifting or timing constraints beyond standard TTL drive capability are specified for RI-MOD-TX8A-00.
Is RI-MOD-TX8A-00 compatible with RI-RFM-008B and RI-ACC-008B?
Yes-RI-MOD-TX8A-00 is explicitly designed for interoperability with RI-RFM-008B (Remote Antenna RF Module) and RI-ACC-008B (Remote Antenna Tuning Board). The module's mechanical dimensions, connector layout, and RF impedance matching assume use with these companion boards; substitution with non-TI tuning boards may compromise resonance tuning and voltage handling.
What is the maximum allowable antenna resonance voltage for RI-MOD-TX8A-00?
The maximum allowable antenna resonance voltage for RI-MOD-TX8A-00 is 350 Vpeak, measured at the antenna terminals under 134.2 kHz excitation. This rating ensures safe operation during high-Q resonant conditions typical of loop antennas in proximity-based RFID readers. Exceeding this voltage risks internal arcing or long-term dielectric degradation in RI-MOD-TX8A-00.
Does RI-MOD-TX8A-00 require external power regulation or filtering?
No-RI-MOD-TX8A-00 accepts unregulated 10–24 VDC input and contains no sensitive analog circuitry requiring low-noise supply. A standard industrial DC power supply meeting ripple and surge specifications per IEC 61000-4-5 is sufficient. No external capacitors, ferrites, or regulators are required for normal operation of RI-MOD-TX8A-00.
