Mucciardi N.5 86020 Campochiaro - (CB) - Italy 2 RF circuit The core component of the RF circuit is the ST25RU3993 chip. It receives digital base-ban transmit data and commands from the MCU via the SPI interface. ST25RU3993 frames the transmitted data accordingly, and automatically encodes it into PIE symbols. Based on the PIE encoded symbols ST25RU3993 creates a sinusoidal shaped modulation signal. The modulation signal can either be ASK or PR-ASK. ST25RU3993 synthesizes an RF carrier frequency with a VCO / integer-n phase locked loop (PLL). The frequency reference for the PLL is a temperature compensated crystal oscillator (TCXO). The carrier frequency is modulated by the ASK or PR-ASK shaped modulation signal. The ST25RU3993 differential output is connected to a 2:1 balun where the transmit signal is transformed from a 100 differential to a 50 single-ended signal. In order to limit cross channel a SAW filter must be placed on the TX-path of the reader, the selected SAW filter is B3717 which is manufactured by TDK. The signal then proceeds to the external power amplifier to generate a high-power output signal with approximately 30 dBm in the default configuration of the board. The output of external power amplifier is connected to a low-pass filter, which attenuates the second and third harmonic of the carrier frequency. The filtered transmit signal to directional coupler, which has a coupling factor of 10 dB. The purpose of this device is to isolate the transmit signal from the receiving inputs of ST25RU3993 and has a major influence on the sensitivity of the reader. The isolated port of the main directional coupler is connected to a 2:1 balun to transform the incoming tag response signal to a 100 differential signal that is connected to the receiving pins of ST25RU3993

Mucciardi N.5 86020 Campochiaro - (CB) - Italy 3 Antenna matching To maintain the sensitivity of the reader the self-jamming signal reaching the receiving inputs of ST25RU3993 needs to be minimized. The self-jamming signal comprises reflections from the antenna and the leakage across the main directional coupler. To minimize the self-jamming signal a carrier cancellation circuit is connected to the coupled port of the main directional coupler. The antenna matching circuit can change its impedance and hence to reflect a certain amount of the coupled power back into the directional coupler. This reflected signal is combined with the self- jamming signal at the isolated port of the main directional coupler. To find the impedance setting of the antenna matching circuit resulting from a self-

jamming signal cancellation the power of the self-jamming signal needs to be measured. Such a measurement capability is provided by ST25RU3993 and is referred to as reflected power measurement. An optimal impedance setting of the antenna matching circuit results in low reflected power. The main components of the antenna matching circuit are two digital tunable capacitors, which are controlled by the microcontroller via the SPI interface. The fixed lumped components of the antenna matching circuit help to center its impedance to 50 and define the impedance step created by one change of a digital tunable capacitor.
