AEKA2192727 MHz Remote Control TX

Circuit Description for Taiyo Kogyo Co., LTD. AEKA21927 Q2 is the crystal oscillator. This feeds the RF amp Q3. L3, L4, and C7 through C9 are the harmonic suppression and antenna matching network. IC 1 supplies the modulation which is base modulated onto the base of Q3. Energy is supplied by a 9V primary cell battery and regulated down to 5.1 Volts by Zener diode D11. This unit uses a fixed antenna of a 6 inch long spring wire. No external ground is available and the only ground is that of the printed circuit board. TAIYO KOGYO CO., LTD.

FCC ID: AEKA21927 REPORT #: T\TAIYO\68JT2\68JT2RPT.doc PAGE #: 1 TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of TIMCO ENGINEERING, INC. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100 kHz and the video bandwidth was 300 kHz. The ambient temperature of the UUT was 72º with a humidity of 75%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was estab- lished by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor sup- plied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m APPLICANT: TAIYO KOGYO CO., LTD.

TEST PROCEDURE: The procedure used was ANSI STANDARD C63.4-1992. The spectrum was scanned from 30 MHz to 1000 MHz. When an emission was found, the table was rotated to produce the maximum signal strength. The antenna was placed in both the horizontal and vertical planes and the worse case emissions were reported. The UUT was tested in 3 orthogonal planes. TEST RESULTS: THE UNIT DOES MEET THE FCC REQUIREMENTS. PERFORMED BY: JOE SCOGLIO DATE: FEBRUARY 1, 2002 APPLICANT: TAIYO KOGYO CO., LTD.

FCC ID: AEKA21927 NAME OF TEST: Occupied Bandwidth RULES PART NO.: 15.227 REQUIREMENTS: The field strength of any emissions appearing outside the 26.96-27.28 MHz band shall not exceed the general radiated emission limits in (15.209). THE GRAPH ON PAGE 5 OF THIS REPORT REPRESENTS THE WORSE CASE OCCUPIED BANDWIDTH EMISSIONS FOR THIS DEVICE. METHOD OF MEASUREMENT: A small sample of the transmitter output was fed into the spectrum analyzer and the attached plot was taken. The vertical scale is set to 10 dB per division. The horizontal scale is set to 10 kHz per division. TEST RESULTS: The unit DOES meet the FCC requirements. PERFORMED BY: JOE SCOGLIO APPLICANT: TAIYO KOGYO CO., LTD.
