This unique synergy allows our system to integrate seamlessly into  and significantly increase productivity for  a wide range of applications and environments. These systems consist of Dura-labels that are designed to store information under extremely harsh environments without requiring a battery and scanners capable of reading the Dura-labels. Communications between the scanner and Dura-label are conducted using a revolutionary two-way technology that provides superior advantages over conventional communication methods. The specific data being communicated, and the amount of interaction you have with the scanner and Dura-label, may be determined by your application. T Page 2 Advantages Data-gathering systems such as bar code readers and conventional Radio Frequency Identification products use one-way communication: a sensor reads information from a device, without any interaction between the two devices. Moreover, bar code systems are subject to line-of-sight limitations. As a result, airborne contaminants such as dust, dirt, oil, and mist, as well as label damage and objects residing outside the line of sight, result in inefficient and erroneous results. The SCS Interactive Identification System overcomes these restrictions by using state-of-th…

Single Chip Systems Corporation MODEL MKRS556 SCANNER Operational Description Purpose: This device is intended for applications in the areas of identification, verification, and inventory control. The system consists of two main parts, a reader and ID tags. The reader is operated by the user to interrogate the tags which are attached to objects in the field. Tags are small in size and have read/write capability. Theory of Operation: The ID tags derive their power from the RF energy of the reader signal, and are not internally powered. Signaling from reader to tag is accomplished by momentarily switching off the RF transmitter in a predetermined pattern. Signaling from tag to reader is accomplished though antenna backscatter. The tag momentarily shorts its antenna terminals together, which causes the transmitted power that was being absorbed into the tag to reflect back off its antenna. This reflected signal sensed by the receiver. Transmitter: The transmitter produces a phase locked CW signal, which is modulated by momentarily switching off the output power. In the transmitter, the phase locked loop output is amplified and then modulated by an RF sw itch w hich is also controlled by the microprocessor. It then passes through the final amplifier, low pass filter, SP6T switch, and ultimately is transmitted from the antenna. Re ce ive r: The received signal from the antenna, comes through the SP6T sw itch, to a pow er divider. The tw o signals from the power divider are quadrature downconverted (to baseband) using an LO derived from the transmitter. The two baseband signals are amplified and filtered, the absolute values are taken, and the two resultant signals are summed. This composite baseband signal goes to a comparitor circuit which provides an input signal to the microprocessor. Ante nna: The model MKRS556 scanner can use up to 6 transmit and receive antennas. Power: Antenna port power is less than 37 dBm. The typical antenna gain will be 7.5 dBi. Modulated Signal Bandwidth: The 20 dB bandwidth of the modulated signal power is less than 1 MHz.

Section 2.1033(c)(10) - Circuit Diagrams and Descriptions The top level circuit diagram for the entire system is shown below in Figure 1. Figure 1. MKRS556 Top Level Schematic Diagram A. Description of frequency determining circuitry The RF frequency is generated using a phase locked loop (PLL) circuit. The licensed frequency data is burned into flash memory. At startup the microprocessor sends the PLL integrated circuit (National Semiconductor’s LMX2325TM) the serial information for the set frequency. The PLL IC uses a 20 MHz crystal oscillator as a reference frequency. The PLL IC generates a voltage for the voltage controlled oscillator (VCO). The VCO generates the RF signal, which is fed back to the PLL IC. The PLL IC divides this signal down, and compares it to the 20 MHz reference. In the closed control loop, the PLL IC’s output voltage is adjusted to precisely maintain the set frequency. B. Description of circuitry used for spurious, modulation and power limiting The MKR S556 RF output is on/off modulated. This modulation is accomplished using the analog gain control pin of an RF amplifier (RF Micro Devices RF2126). This gain control is set with a discrete signal from the field programmable gate array (FPGA). An RC filter on this line provides transmission bandwidth limiting. Spurious emissions are limited by a 3 section, low-pass filter located at the output of the final RF amplifier. The RF output power level is set using an analog control voltage in the amplification stage prior to the final amplifier. During final assembly, a digital potentiometer is adjusted to provide a desired output power at the RF output port. The digital potentiometer value that corresponds to the desired output power is then burned into flash memory. C. Description of Modulation technique and circuitry The MKR S556 Transceiver uses an RF on/off modulation scheme. The RF signal powers the ID tag in the field, and then communicates with the tag by briefly turning off the RF power at the proper time. The waveform timing and duty cycle depend on the transmitted symbol. There are 3 transmitter waveforms. The transceiver is either sending just a clock, sending a logic “0”, or sending a logic “1”. Figure 2 shows the timing for each of these waveforms. The range of time for the next frame of data or clock varies as a function of the interrupt latency of the microprocessor. The modulation either has the RF at full strength in the “on” state, or attenuated by at least 20 dB in the off state. Any time the scanner is normally operating, the RF signal is continuously being modulated. The system is operating CW (unmodulated) only when the transceiver is instructed to operate as such, via operator command. The sequence of clock, logic “0” and logic “1” information being transmitted is completely dependent on the commands issued by the processor, and by the tag responses. The modulation of the signal is controlled with a digital pulse sequence from the FPGA. This signal is RC filtered to limit the transmission bandwidth, and then is sent to the analog gain control of an RF amplifier. The RF amplifier attenuates the RF signal by a minimum of 20 dB when in the “off” state.

This application is for a transceiver, or scanner, which is part of an RF ID system, to be used in licensed sites under 47 CFR 90.35. The scanner generates an RF signal between 2.453 and 2.481 GHz. This signal is used to power and communicate with a passive label. The scanner uses externally connected antennas to radiate and receive RF energy. The scanner can selectively multiplex between 1 to 6 antennae. The number of antennae is user configurable depending on the application requirements. The scanner connects to the antennae using 2 flexible coaxial cables. One cable connects to the transmit side of the antenna, and the other connects to the receive side. Single Chip Systems intends to sell 2 types of antennae which have either 7.5 dBi or 8.5 dBi of gain. Again, the number and type of antennae used will depend on the user’s application requirements. 1.
