Overview The MUF V2 module serves as the core radio frequency (RF) engine embedded across all STid UHF RFID reader products. It operates within the 860–930 MHz frequency band, ensuring compatibility with global UHF RFID standards and enabling reliable long-range identification performance. Designed exclusively for internal integration, the MUF V2 is a proprietary module and is not intended for standalone commercialization or external distribution. It is fully optimized to meet the performance, compliance, and robustness requirements of STid’s UHF reader portfolio. The module provides high-efficiency RF signal processing, stable communication capabilities, and seamless integration within STid hardware architectures, making it a critical component in delivering consistent and high-performance RFID reading solutions. 4 III. Composition IMPINJ E710 Tranceiver The reader chip implements direct conversation receiver architecture, and operate in the worldwide UHF industrial band. It contain all RF and baseband blocks to interrogate and receive data from compatible UHF RFID tags, and an integrated microcontroller with embedded firmware providing the GS1 UHF Gen2 RAIN protocol as a pre-integrated feature. The Impinj E710 reader chip contain power detectors connected to the RX and LO pins, allowing measurement of forward (transmit) power on the LO pin and reverse power on the RX pin. These power detectors convert the RF power level at the RX and LO pins into analog voltages, which are measured by the Auxiliary ADC inside the reader chip. Directional coupler Our MUF radio transceiver board use a directional coupler to isolate the transmit (TX) signal and the receive (RX) signal, to reduce self-jammer, and to sample a local oscillator (LO) for use in self-jammer cancellation, for forward power measurement and down sampling of the received signal MMCX Crystal for MCU STM32 Input and output RF signal 5 Host Controller The Host Controller is a microcontroller responsible for managing communication with the Impinj RF reader IC and controlling its operational behavior. It acts as the central interface between the system firmware and the RF front-end, issuing commands and handling data exchange required for RFID operations. Communication between the Host Controller and the Impinj reader chip is implemented via a Serial Peripheral Interface (SPI). In this configuration, the Impinj device operates as an SPI slave, while the Host Controller functions as the master, initiating all transactions and controlling data flow. Additional digital lines are used to synchronize and manage SPI communication, ensuring reliable and deterministic operation. The interface also includes configurable Digital Input/Output (GPIO) pins. These pins can be programmed as inputs or outputs depending on system requirements and are used to support control, status monitoring, and hardware-level signaling between the Host Controller and the RF subsystem. IV. RF Operation (MUF Core Module) All radio frequency (RF) operations within the STid UHF RFID reader products are fully managed and executed by the MUF module, which serves as the core RF engine of the system. Upon power-up, the MUF module automatically performs an internal tuning and calibration procedure within its integrated RF transceiver. This process dynamically adjusts internal capacitive and resistive elements of the RF front-end to optimize impedance matching at the selected carrier frequency. As a result, the MUF ensures optimal receiver sensitivity and consistent bandwidth performance across the entire operating frequency range (typically 902 MHz to 928 MHz, depending on regional configuration). This initial calibration is designed to guarantee proper operation across all frequency hopping channels. In addition, at each RF activation, the MUF continuously monitors matching conditions and autonomously readjusts its internal network if necessary, ensuring stable and reliable RF performance without external intervention. The MUF module integrates a shared local oscillator for both transmission and reception paths, generated by an internal phase-locked loop (PLL) frequency synthesizer. This architecture inherently synchronizes frequency changes during hopping sequences, maintaining coher…
