The EUT is A frequency modulation Wireless Microphone with following features: 1. Operation Frequency Range:630 - 660MHz; 740 - 770MHz. 2. Type of Modulation:FM, 161KF3E. 3. The emission designator is 161KF3E. The calculation is (2M+2DK), K=1 and (2 x 32.768 + 2 x 48) = 161.5kHz, so the emission designator is 161KF3E. 4. This Wireless Microphone operates within UHF band with PLL synthesized.

UF-9 TRANSMITTER PROCEDURE 1. Audio from the microphone is coupled through IC BA4510 applied to Audio amplifier and buffer stage. Adjust VR R4 to control audio amplify level. 2. (Variable Capacitance Diode) of the VCO modulate the audio signal into RF signal 3. The RF signal of 630MHz to 660MHz is generated from VCO and is locked via PLL IC U4 when selected. Adjust VC C31 to correct the exact frequency.. 4. The locked RF signal is coupled to bufferQ13and amplifiers Q12 & Q11. 5. After RF pre-amplify and final amplify, L7,L8,C41 & L9,L10,C50 to filter the spurious and harmonics and have the correct frequency pass through the maximum pass-point of the filter to transmit out. At this stage, the RF level is about 7dBm. MASCOT ELECTRIC CO, LTD DATE APR 15 2004 UF-9 TRANSMITTER PROCEDURE 1.
