Wireless microphone circuit description 电路说明 AUDIO CIRCUIT 音频部分 The audio signal is injected via the microphone sensor into the electronic switch (U5 CD4066). Then the audio signal is amplified (U3 4558) and via pre-weight circuit composed of R79, R99, C77, C78，C68 with a compress circuit (U4 NE571). The level of the output signal is controlled by the resistor VR2 to modulation part. MODULATOR CIRCUIT 调制部分 The modulator circuit is direct FM type built around the local oscillator (VCO) composed of Q29, Q32, VD1, VD2, VC2 and a resonator DR1 and controlled by PLL (U3 E035L) with 4MHz Crystal as its clock to generate a set carrier needed. The audio signal can be piloted by a 45kHz crystal oscillate circuit and be delivered to modulation transistor Q29 (BFP420) after VR1, the output signal from Q32 is sent to RF pre-amp. RF PRE-AMPLIFIER & FINAL AMPLIFIER 放大部分 Three transistor amplifier stages, using Q3/Q7(BFR520), & Q9(BF998R), culminating with a normal transmitter output of <1mW. The output filter comprised of L56, L3, L4 and VC1, C21, C14, C5, C4, C8 and filter FL1(DF915) suppresses the output harmonics and matches the output to the integrate antenna. Operation and Display (操作和显示部分) A MCU (U9 89S52) with a 12MHz crystal as its clock and accessory (U11, U1, U4) controlled operation interface and U13 HT1621 driving LCD display. POWER CIRCUIT 电源部分 The power is controlled by U6 and Q33, 37 for analysis circuit part, and U7 and Q14, Q19, Q26, Q28 for digital circuit part. Operation frequency range: 614.2-697.8 MHz; Modulation Type: 80kF3E Antenna type: Whip Antenna
