Reference No.: PDS-R4274 Rev.: 00-06E Sheet: 2 Scope NJR4274 K-band (24GHz) Doppler Module has been designed for motion sensing applications. Main Structure  Integrated antenna structure, the patch antenna is integrated on the module PCB.  All of electric parts except interface connector are covered with metal cap. Operation Overview  5 V input operation, LDO integrated.  Implemented an internal MCU for RF frequency tuning of RF-IC and intermittent-operation.  Internal MCU controls ON/OFF of Output voltage from LDO which connect to the input voltage terminal of RF IC.  This module is 2-frequencies CW (FSK) type sensor that can simultaneously measure the distance and velocity of the moving target. It operates duty cycle of intermittent-operation has 2-operation- mode (Normal operation mode / Low power operation mode). 2-operation-mode are different duty cycle. (refer Fig.2)  RF frequency is output during ON time.  Internal MCU supplies the tuning voltage to RFIC and the RF frequency is controlled by tuning voltage.  Since the RF frequency is switched every intermittent-operation cycle, the tuning voltage is switched every cycle.  Switched RF frequency is 2-frequencies, and difference of those 2-frequencies is 15 MHz +/- 3 MHz.

FCC ID: 2ACUJR4274 Prüfbericht - Produkte Test Report - Products RF Exposure Statement: JP2125FA 003 Seite 1 von 2 Page 1 of 2 Client: Nisshinbo Micro Devices Inc. (*) 1-1, Fukuoka 2-Chome, Fujimino-City, Saitama, 356-8510 Japan Test item: K-Band Doppler Sensor Module (Movement Sensor) Identification: NJR4274 FCC Requirement According to FCC §2.1093 (d)(1), Portable Devices that transmit at frequencies above 6 GHz must comply with the following applicable limit for maximum permissible exposure (MPE) specified in FCC §1.1310 (e)(1), Table 1: Equipment Use Frequency Range [MHz] Power Density Limit Average Time [min] General Population / Uncontrolled Exposure 1,500 – 100,000 1.0 [mW/cm 2 ] <30 Note: This evaluation was conducted at 2cm test separation distance (variable r in the statement). It was specified by the customer. Measurement Result The maximum measured E-field strength and corresponded estimated EIRP from the transmitter are given in the following table: Freq. [GHz] Wave Length [cm] Measured E-Field Strength E Meas. Distance R [m] Calculated EIRP Test Distance r [cm] Calculated Power Density S [mW/cm 2 ] [dBuV/m] [V/m] [mW] [dBm] 24.17122870 1.2411 80.47 0.0106 3.0 0.033708 -14.723 2.0 0.000671 Note: The EIRP in mW is calculated in conjunction with the following formula: EIRP = (E × R) 2 /30 = (0.0106 × 3.0) 2 / 30 = 0.000033708 [W] = 0.033708 [mW] TÜV Rheinland Japan Ltd. – Global Technology Assessment Center 4-25-2 Kita-Yamata, Tsuzuki-ku, Yokohama 224-0021, Japan FCC ID: 2ACUJR4274 Prüfbericht - Produkte Test Report - Products RF Exposure Statement: JP2125FA 003 Seite 2 von 2 Page 2 of 2 The power density S in mW/cm 2 is calculated in conjunction with the next formula: S = EIRP / (4 × π × r 2 ) = 0.033708 / (4 ×π × 2.0 2 ) = 0.000671 [mW/cm 2 ] Since the shortest wave length λ of transmitter is 1.2411cm, above mentioned calculations are considered in far field condition. Normal mode is the worst case configuration of this transmitter, therefore above mentioned condition is considered as the most severe estimation. For details, refer to the relevant sections that is submitted test report, JP216XYU 002. Conclusion This transmitter module is classified as Portable Devices by the client. SAR evaluation is not required since nominal frequency of the transmitter is higher than 6GHz, therefore, RF exposure evaluation (MPE) was conducted by the above-mentioned calculated method. As a result, calculated Power Density S is below FCC limit at the separation distance of 2cm. Note: This RF Exposure Evaluation (JP2125FA 003) replaces the original evaluation (JP2125FA 001).
