CIRCUITS TO SUPPRESS SPURIOUS RADIATION, LIMIT MODULATION AND CONTROL POWER 1) VCO section The oscillator circuit formed by L303, D305 and D306 generates transmitter frequencies. Then this signal is fed to the 3-stage of amplifiers, buffer amplifier Q302, pre,-ampufler IC301 and post amplifier Q303 and lead to the final amplifier. 2) PLL section Basically, the circuit description is the same as Rx. PLL IC inclusive with pre-scaller IC205 compares the phase between the VCO signal and reference oscillator frequency (12.00NMz) by method of dividing the frequency, and produces VCO control signal. Then this VCO control signal is fed to the charge pump, consisting of Q206, Q207 and Q208, and fed to the LPF. The supply voltage of charge pump is amplified by IC206 (approx. 15V) to achieve greater C/N ratio. 3) Modulator section The modulation signal is fed to both VCO and the reference oscillator (TCVXO), this permits a very flat modulation characteristics against low frequency (DC). This is the advantage when KG510 is used for POCSAG transmitter. 4) Tx younger section The VCO signal is amplified by Q215 and Q216 to achieve 250mW. But VHF bands (136-174MHz) has only stage of amplifier Q215 to achieve l00mW. 5) PA section The signal from younger stage is fed to PM510 and Q510 (VHF bands have no Q501) to achieve 50W output power. Then, signal is fed to the LPF to eliminate the harmonics spurious frequencies. An APC circuit formed by IC502, IC503, Q504 and Q505 stabilizes the output power at the set level. An IC501 protects PM501 and Q501 from the reverse power caused by the unmatched aerials. CIRCUITS TO SUPPRESS SPURIOUS RADIATION, LIMIT MODULATION- AND CONTROL POWER FCC ID: O6E713050B

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 Bird 8325 attenuator as a 50 ohm dummy load. Maximum power measured was 70 watts; and with software programming minimum power was 25 watts. (The transmitter was tuned by the factory.) 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 a Audio Precision System One TRMS voltmeter and tracking generator. 2. Modulation limiting curves are shown in Figures 2a and 2b for wide or narrow channel operation respectively, using a Boonton 8220 modulation meter. Signal level was established with a Audio Precision System One TRMS voltmeter. The curves show compliance with paragraphs 2.987(b), and 90.211(c). 3. Figure 3 is a graph of the post-limiter low pass filter which meets the requirements of paragraph 90.211(d)(1) 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 selective voltmeter on the Boonton 8220 modulation meter audio output. 3 D. MODULATION CHARACTERISTICS 4. Occupied_Bandwidth (Paragraphs 2.989(c), 90.209(b)(4) and 90.210(d) of the Rules) Figures 4a, 4b, 4c and 4d are plots of the sideband envelope of the transmitter for both 70 and 25 watt output taken with a TEK 494P or Advantest R3361A spectrum analyzer. Modulation corresponded to conditions of 2.989(c)(1) and consisted of 2500 Hz tone at an input level 16 dB greater than that necessary to produce 50% modulation at 2379 Hz, the frequency of maximum response. Measured modulation under these conditions was 4.1 kHz, or 1.9 kHz for 25 or 12.5 kHz channelization respectively. For the 12.5 kHz channelization, RBW was 100 Hz, VBW 100 Hz, max hold, multiple scan per 90.210(d)(4). All plots have unmodulated carrier as 0 dBm reference. 4 FIGURE 1 MODULATION FREQUENCY RESPONSE MODULATION FREQUENCY RESPONSE FCC ID: O6E714050B FIGURE 1 5 FIGURE 2a AUDIO LIMITER CHARACTERISTICS AUDIO LIMITER CHARACTERISTICS FCC ID: O6E714050B FIGURE 2a Wideband (5 kHz) 6 FIGURE 2b AUDIO LIMITER CHARACTERISTICS AUDIO LIMITER CHARACTERISTICS FCC ID: O6E714050B FIGURE 2b Narrow band (2.5 kHz) 7 FIGURE 3 AUDIO LOW PASS FILTER RESPONSE AUDIO LOW PASS FILTER RESPONSE FCC ID: O6E714050B FIGURE 3 8 FIGURE 4a 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 = 61 than 250% of the authorized bandwidth (over 50 kHz) OCCUPIED BANDWIDTH (70 W) FCC ID: O6E714050B FIGURE 4a (5 kHz) 9 FIGURE 4b 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 = 57 than 250% of the authorized…
