Liepa Subject: RE: 15.515 / 15.521 Measurements Page 1 of 1 10/12/2004 Question: If the peak detected emissions from a device meet the RMS EIRP limits, with all Spectrum Analyzer settings identical to the requested RMS detected method except with peak detection, is that sufficient to demonstrate compliance with said limits? (Since the peak detected values will always be greater than the RMS detected values for every bin of the spectrum analyzer output.) Our Spectrum Analyzer does not have the built in RMS detector function and, so long as the device meets the EIRP limits with a peak detector, we prefer not to use the alternative method for determining RMS values as it is an exceptionally long and complicated test. Answer: Yes, you can use a peak detector. Use of a peak detector is sufficient to demonstrate compliance with the RMS limits.

Delco Electronics Systems Proprietary Radar System Design ‹ Design Drivers – Small targets at 5 meters distance : Good system detection sensitivity – Precision Ranging capability : MU ST have large radiated bandwidth – Wideband FCC frequency allocations demand very low transmitter power – Low transmit power + good system sensitivity means » Sensitive receiver required » Efficient waveform for detection is necessary ‹ Waveform – Continuous Wave radiation modulated in phase by a high speed pseudo noise code – Phase modulation is binary phase shift key (BPSK) – Code modulated continuous wave provides efficient waveform and good range precision Delco Electronics Systems Proprietary Principles of Operation ‹ Range Bin Definition – As a target range (time delay) varies slightly about the time (range) delay imparted to the receive code, the receiver output (voltage) varies to less than maximum. The range response of the system for a fixed return signal power is as follows R n range receiver output Delco Electronics Systems Proprietary Principles of Operation ‹ The POSITION of the range bin in space is determined by the time delay of the receive code – The entire range is covered by scanning the single range bin in range – Scanning is accomplished by adjusting the time delay value of the receive code ‹ The WIDTH of the range bin (depth of bin in space) is determined by the period of one bit of the pseudo noise code sequence – high speed code clocks = thin range bins Delco Electronics Systems Proprietary Principles of Operation ‹ Achieving Receiver Sensitivity – Direct detection of the LO signal which comes out of the receive phase modulator cannot provide adequate receiver sensitivity – The transmit LO signal is further modulated by a data stream to provide an AC signal after down conversion for detection. ²Ø ²Ø delay unit code generator receive transmit LO receive code transmit code data carrier with "data" sidebands data I Q target Delco Electronics Systems Proprietary Principles of Operation ‹ Diagnostics – There is an “End to End” diagnostic function implemented, which gives very high coverage of detecting failures – This feature is accomplished by positioning the system range bin such that it contains the transmit and receive antennas. – Direct coupling between antennas provides a reliable signal injection into the receiver ²Ø ²Ø delay unit code generator receive transmit LO receive code transmit code data LO with "data" sidebands data I Q direct coupling provides Diagnostic signal range bin positioned over antennas with the proper delay value

Receive Chain Emissions: RBW=1 MHz, VBW>=RBW; measurement distance 0.3 m, peak detection, peak hold. Data compared with FCC Class B limit for reference, Table 6.2. The 8.236 GHz radiated emission is not an emission from the TX chain, but is a spurious emission emanating from the device receive chain LO (the doubler in the RX chain requires the largest portion of the LO power, the reference signal to the transmitter is 14 dB lower). The 8 GHz emission does not radiate at a level above the UWB emission from the transmitter’s antenna, as computed from the theoretical performance of the BPSK digital encoder and both the calculated and measured response of the TX chain Bandpass Filter (-30 dB at 8 GHz). The waveform associated with the particular PN code has the center spectral line reduced by 36 dB relative to the first upper and lower spectral lines of the waveform. Thus, this emission is solely an emission from the receiver portion of the radar. The 16.472 GHz emission is an LO generated for use only in the receive chain of the radar (see block diagram). The 32.944 GHz emission is the 2 nd harmonic of the LO generated for use only in the receive chain of the radar. 6.5 Emission Attenuation Above Horizon (FCC 15.515(c)) Figure 6.11, 6.5.

Total Emission Level Compliance 30 o min -24.0 dB -58.3 dBm @ 24.00 GHz -82.3 dBm < -76.3 dBm beyond 1/1/2014 6.6 Health Hazard EM Radiation Level Health hazard radiation levels are computed from the measured EIRP value following FCC OET Bulletin 65 as follows, where S is power density, Power density is formulated as: S(mW/cm 2 ) = EIRP(mW)/(4π R(cm) 2 ) The highest peak power density in the 10 dB UWB Bandwidth of the DUT recorded with a 1 MHz RBW, as reported in Table 6.1 is -50.8 dBm. Using the UWB bandwidth of the device (1.003 GHz), the maximum EIRP over the emission bandwidth can be computed as: EIRP max = EIRP (dBm) + 10 Log 10 (BW/1MHz) = -41.9 dBm + 30.0 dB = -11.9 dBm = 64.6 uW Thus, the maximum power density at a distance of 20 cm is computed as: S(mW/cm 2 ) = 0.0646 mW / (4π 20(cm) 2 ) = 13 nW/cm 2 6.7 Conducted Emission Measurements Not applicable. 6.8 Effect of Supply Voltage Variation The DUT is designed to operate on 13.4 VDC, originating from a vehicular 12-volt system. The relative radiated emissions and frequency were recorded at the "fundamental" (24.69 GHz) as the supply voltage was varied from 8 to 16 VDC. Figure 6.12 shows the emission power variation. Current at 12.0 VDC was 445 mA.

Brunett Valdis V. Liepa Research Scientist Summary Tests for compliance with FCC Regulations, according to Part 15.515, were performed on Delphi Automotive Systems UWB Radar. In testing completed on October 24, 2005, the device tested met the UWB emission limits at the fundamental by 1.9 dB at f M , and by more than 0.3 dB for all other UWB emissions. With regard to RF exposure, the maximum RF field at a 20 cm distance was calculated to be 13.0 nW/cm 2 . The DUT is designed for vehicular applications, and as such, digital emissions from support circuitry are not subject to FCC Part 15, Subpart B; however, these emissions were recorded in the process of characterizing the device. Radiated digital emissions from circuitry used to enable the operation of the UWB transmitter meet the FCC/IC Class B (15.209) limit by 15.4 dB.

Configuration and Identification of Device Under Test The Device Under Test (DUT) is a 24 GHz UWB Radar. It is a BPSK (Binary Phase Shift Keyed) system with a constant amplitude 24.7 GHz signal modulated at keying frequencies of 625 MHz and 1250 MHz. The size of the DUT is 25(W) x 10(H) x 3(D) cm with a single connector on the backside. The DUT is a complete radar unit; however, additional signal processing and controlling may be performed by other processors on the vehicle.
