The switch operation “wake’s up” the encoder, and the internal clock circuit turns on. The encoder generates data internally based on the timing of the clock oscillator. The data is outputted from the encoder to the 315 MHz, SAWR (Surface Acoustic Wave Resonator) stabilized oscillator. This oscillator is then turned on and off at the data rate outputted from the encoder. The oscillator radiates out through a PCB trace antenna. 315 315 MHz SAWR oscillator Encoder With integratedclock ill t Buttons PCB trace Antenna

Operational Description

5200 Auto Club Dr. Dearborn, Michigan 48126-9982 (313) 593-9000 Re: Certification for Lear Corporation Transmitter, Model RLC-X, RLC-C+ FCC ID: KOBLEAR1XT CANADA: DESCRIPTION OF OPERATION GENERAL DESCRIPTION The product for which certification is pursued will be manufactured for GM Motor Company by Lear Corporation (formerly United Technologies Automotive) for automotive applications. This 315 MHz transmitter works in conjunction with a receiver that is mounted in the vehicle. The transmitter is a 3 volt, single cell battery operated fob type that is carried by the user. It is part of a keyless entry system and can be used to perform certain functions such as lock and unlock the driver and passenger doors, open the trunk, etc... depending on how the receiver module in the vehicle is programmed. There are seven versions of this transmitter. The only difference between these seven units are the number of buttons used, the printing on the buttons, and the GM/UTA part number stamped on the back. Electrically, all seven units are identical. The transmitter fob contains one 3 volt battery and a printed circuit board assembly. The two piece exterior housing is injection molded plastic, with the GM/UTA #, FCC ID #, and CANADA # stamped into the plastic. TECHNICAL DESCRIPTION When the buttons are depressed, the encoder IC will power up and generate the proper data code which can only be recognized by a matched receiver. The code is carried by 315 MHz carrier with AM OOK (on-off keying) modulation and radiated by a printed circuit board antenna. The data code is of a pulse width modulation format to express bits “0” and “1”. The data code period is controlled by the encoder clock, which is an RC oscillator type that is integrated into the encoder. The antenna is a PCB trace and is a mono-pole type. The 315 MHz transmit frequency is generated by a SAWR (Surface Acoustic Wave Resonator) stabilized, Colpits oscillator. Frequency tolerance is better than 315 MHz, +/- 150 kHz.

In addition, the requirements of section 15.35 for averaging pulsed emissions and for limiting peak emissions were met. The field strength of harmonic and spurious emissions did not exceed 604 μV/M (AVERAGE). 15.231 (c) -The device operates at 315 MHz. The bandwidth of emissions did not exceed 0.25% of the operating frequency (787.5 kHz). DETERMINATION OF FIELD STRENGTH LIMITS The field strength limits shown below are found in Section 15.231. Frequency Limit F1=2603750 =L1 Fo=315Lo F2=47012500 =L2 The formula below was utilized to determine the limits: Limit = L1 + [(Fo-F1)(L2-L1)/(F2-F1)] Solving yields: Fundamental Limit= 6,040 μV/M (AVERAGE) @ 3 Meters Harmonic Limit= 604 μV/M (AVERAGE) @ 3 Meters Test Report No. R-8284-1 FCC ID: KOBLEAR1XT REPORT OF MEASUREMENTS (continued) DETERMINATION OF DUTY CYCLE The following information was supplied by Lear Corp. Transmitter On Time=31.6 milliseconds (maximum- worst case in 100 ms) Transmitter Cycle Time => 110.0 milliseconds Transmitter Duty Cycle=31.6 % Duty Cycle=31.6 % Correction Factor = 20 log(0.316) =-10.0 dB SPECTRUM ANALYZER DESENSITIZATION CONSIDERATIONS Due to the nature of the emissions being measured, care was taken to ensure that the resolution bandwidth of the spectrum analyzer was adequate to provide accurate measurements. The following formula was utilized: Setting pulse desensitization equal to zero and utilizing the minimum observed pulse width of 200μs yields a minimum required bandwidth of 3333.3 Hz. FCC specified bandwidths of 100kHz and 1 MHz were utilized below and above 1 GHz, respectively. Test Report No. R-8284-1 FCC ID: KOBLEAR1XT REPORT OF MEASUREMENTS (continued) GENERAL NOTES 1. All readings were taken utilizing a peak detector function at a test distance of 3 meters. 2. The duty cycle was applied to the peak readings in order to determine the average value of the emissions. 3. All measurements were made with 3 VDC derived from a new CR2032 battery. 4. The frequency range was scanned from 30 MHz to 3.15 GHz. All emissions not reported were more than 20 dB below the specified limit.
