ENGINEERING STATEMENT For Certification of AIRTECH INFORMATION & COMMUNICATION CO., LTD. Model No. ARH-465 FCC ID: ONKARH-465 I am an Electronics Engineer, a principal in the firm of Hyak Laboratories, Inc., Springfield, Virginia. My education and experience are a matter of record with the Federal Communications Commission. Hyak Laboratories, Inc. has been authorized by Airtech Information & Communication Co., Ltd. to make certification measurements on the ARH-465 transceiver. These tests were made by me or under my supervision in our Springfield laboratory. Test data and documentation required by the FCC for certification are included in this report. The data verifies that the above mentioned transceiver meets FCC requirements and certification is requested. _________________________ Rowland S. Johnson Dated: September 21, 2000 A. INTRODUCTION The following data are submitted in connection with this request for type acceptance of the ARH-465 transceiver in accordance with Part 2, Subpart J of the FCC Rules. The ARH-465 is a hand-held, battery operated, UHF, frequency modulated, 2 W (conducted rating) transceiver intended for voice communications applications in the 462.5500 - 462.7250 MHz band under Part 95 in the GMRS service. (ERP (d) was 1.7 W.) B. GENERAL INFORMATION REQUIRED FOR TYPE ACCEPTANCE (Paragraph 2.983 of the Rules) 1. Name of applicant: Airtech Information & Communication Co. 2. Identification of equipment: FCC ID: ONKARH-465 a. The equipment identification label is submitted as a separate exhibit. b. Photographs of the equipment are submitted as separate exhibits. 3. Quantity production is planned. 4. Technical description: a. 16k0F3E emission b. Frequency range: 462.5500-462.7250 MHz. c. Operating power of transmitter is fixed at the factory at 2 watts (conducted). d. Maximum power permitted under FCC Part 95 (interstitial) is 5 watts ERP. The ARH-465 fully complied with that power limitation. d. The dc voltage and dc currents at final amplifier: Collector voltage: 6.9 Vdc Collector current: 0.61 A f. Function of each active semiconductor device: See Appendix 1. g. Complete circuit diagram is submitted as a separate exhibit. h. A draft instruction book is submitted as a separate exhibit. i. The transmitter tune-up procedure is submitted as a separate exhibit. 2 B. GENERAL INFORMATION (continuted) j. A description of circuits for stabilizing frequency is included in Appendix 2. k. A description of circuits and devices employed for suppression of spurious radiation and for limiting modulation is included in Appendix 2. l. Not applicable. 5. Data for 2.985 through 2.997 follow this section. C. RF POWER OUTPUT (Paragraph 2.985(a) of the Rules) RF power output was measured with a Bird 4421 RF power meter and a Narda 765-20 attenuator as a 50 ohm dummy load. Maximum power was 2.0 watts. (The transmitter was tuned by the factory.) For ERP (d) computation see Table 2. D. MODULATION CHARACTERISTICS 1. A curve showing frequency response of the transmitter is shown in Figure 1. Reference level was audio signal output from a Boonton 8220 modulation meter with one kHz deviation. Audio output was measured with an Audio Precision System One TRMS voltmeter and tracking generator. 2. Modulation limiting curves are shown in Figure 2, using a Boonton 8220 modulation meter. Signal level was established with an Audio Precision System One. The curves show compliance with paragraphs 2.987(b) and 95.633(b). 3. Figure 3 is a graph of the post-limiter low pass filter which meets the requirements of paragraph 95.633(b) in providing a roll-off of 60Logf/3 dB where f is audio frequency in kHz. Measurements were made following EIA RS-152B with an Audio Precision System One on the Boonton 8220 modulation meter audio output. 4. Occupied_Bandwidth (Paragraphs 2.989(c), 90.209(b)(4), and 95.629(a) of the Rules) Figure 4 is a plot of the sideband envelope of the transmitter output taken with a Tektronix 494P spectrum analyzer. Modulation corresponded to conditions of 2.989(c)(1) and consisted of a 2500 Hz tone at an input level 16 dB greater than that necessary to produce 50% modulation at 2186 Hz, the frequency of maximum response. Measured modulation at 2186 was 5 kHz. 3 C. MODULATION CHARACTERISTICS (continued) The plot is within the limits imposed by Paragraph 90.211(h) for frequency modulation. The horizontal scale (frequency) is 10 kHz per division and the vertical scale (amplitude) is a logarithmic presentation equal to 10 dB per division. 5. Emission Designator Calculation: (2D + 2F) 2x5.0 + 2x3.0 = 16k0F3E 4 FIGURE 1 MODULATION FREQUENCY RESPONSE MODULATION FREQUENCY RESPONSE FCC ID: ONKARH-465 FIGURE 1 5 FIGURE 2 AUDIO LIMITER CHARACTERISTICS AUDIO LIMITER CHARACTERISTICS FCC ID: ONKARH-465 FIGURE 2 6 FIGURE 3 AUDIO LOW PASS FILTER RESPONSE AUDIO LOW PASS FILTER RESPONSE FCC ID: ONKARH-465 FIGURE 3 7 FIGURE 4 OCCUPIED BANDWIDTH ATTENUATION IN dB BELOW MEAN OUTPUT POWER Required On any frequency more than 50% up to and including 100% of the 25 authorized bandwidth, 20 kHz (10-20 kHz) On any frequency more than 100%, up to and including 250% of the 35 authorized bandwidth (20-50 kHz) On any frequency removed from the assigned frequency by more 43+10LogP = 46 than 250% of the authorized (P = 2.0W) bandwidth (over 50 kHz) OCCUPIED BANDWIDTH FCC ID: ONKARH-465 FIGURE 4 8 E. SPURIOUS EMISSIONS AT THE ANTENNA TERMINALS (Paragraph 2.991 of the Rules) The ARH-465 transmitter was tested for spurious emissions at the antenna terminals while the equipment was modulated with a 2500 Hz signal, 16 dB above minimum input signal for 50% (2.5 kHz deviation) modulation at 2186 Hz, the frequency of highest sensitivity. Measurements were made with Tektronix 494P spectrum analyzer coupled to the transmitter output terminal through Narda 765-20 microwave power attenuator. During the tests, the transmitter was terminated in the 50 ohm attenuator. Power was monitored on a Bird 43 Thru-Line wattmeter; dc supply was 7.5 …
