Revision Matrix Revision Date Description 1 11/28/2018 Cheng Qi updated RF numbers 2 11/30/2018 Cheng Qi updated numbers with tx power margin Reader Transmitter: Transmitter center frequency (MHz) 5800 MHz Does transmitter frequency hop? If so, No describe the pattern and dwell times. Tuning range of transmitter — in other words, The center frequency is fixed. does the center frequency of the transmitter change, if so, over what range? 3-dB bandwidth of transmitter (kHz) BW of CW signal source (PLL) is 20 kHz Peak RF power (W) 0.250 W Peak ERP (W) 1.779W Maximum transmitter field strength 0.08 (volts/meter); assume 1 meter from the source and transmitter radiating with deployed antenna Frequency Upper [MHz] 5801 Frequency Lower [MHz] 5799 Circuit Loss: [dB] Frequency tolerance of center frequency (+/- +/- 0.0017% %) Type of modulation (BPSK, GMSK, etc…) Continuous Wave (No modulation) Antenna Type Antenna gain (dBi) 8.5 dBi Antenna beam width (deg) 86 deg Antenna polarization linear Antenna Axial Ratio: [dB] Antenna pattern:


Reader Receiver: Transmitter center frequency (MHz) 5800 MHz BW of modulated backscatter The front-end filter 3-dB bandwidth is 125 MHz Type of modulation (BPSK, GMSK, etc…) The receiver is designed to receive a BPSK modulated signal from the RF tag Total data rate 125 KHz Antenna gain (dBi) 8.5 dBi Antenna beam width (deg) 86 deg Antenna polarization linear Antenna description Receiver Noise Temp (K) 350 K Receiver Sensitivity (dBW) -85 Necessary Bandwidth per NTIA redbook, MHz 20 dB Bandwidth, MHz 60 dB Bandwidth, MHz Receiver span (MHz) 150 MHz Intermediate Frequency(ies), MHz N/A Local Oscillator frequency, MHz 5800 MHz Transmit Antenna output (EIRP), dBW N/A Receive Antenna Flux Density, dBW/m2 (receiver ON) Receiver Input Damage Threshold, (line loss included), dBm (If Spaceflight is not provided Receiver Input Damage Threshold, Spaceflight will assume -40dBm) Antenna pattern:
