FCC ID: LTQJ4TR IC: 3659A-J4TR 1. Mobile MPE Calculation Summary using a 20cm separation distance: Power Density Power Density Mode Output Power (mW/cm2) (µW/cm²) J4TR 76-81 GHz 119.43 dBµV/m 0.05234213 52.34213 Vehicular Short-Range Radar @ 3 meters 2. Mobile MPE Calculation using a 20cm separation distance: Using Power Density formula: PG S= 4πR where: S = power density P = power input to the antenna G = power gain of the antenna in the direction of interest relative to isotropic R = distance to the center of radiation of the antenna Measured Field Strength --Radiated: 119.43 (dBuV/m) Maximum peak output power --Radiated: 263.1002463 (mW) Antenna gain(typical): 0.00 (dBi) Maximum antenna gain: 1 (numeric) Prediction distance: 20.00 (cm) Prediction frequency: 76000 (MHz) Applied Limit: 1 (mW/cm2) Power density at prediction frequency: 0.05234213 (mW/cm2) Margin of Compliance: -12.81 (dB) TÜV SÜD AMERICA INC 10040 Mesa Rim Road San Diego, CA 92121-2912 Phone: 858 678 1400 FAX: 858 546 0364
