UHF PLL Diversity Wireless Receiver Wireless Microphone Systems User Guide 12 PAW-1000 System Frequency Band Selection Congratulations! Welcome to the PAW-1000 wireless system. To users who need to build an advanced UHF radio system, PAW-1000 provides an excellent solution. With 160 frequency bands, PAW-1000 is applicable for various occasions of radio-cast such as live shows, broadcast, meetings, instrument pickups etc. Touch buttons and liquid crystal displays are equipped within all the components for fast and simple system setup. Most countries closely regulate the radio frequencies used in the transmission of wireless information. These regulations state which devises can use which frequencies, and help to limit the amount of RF (radio frequency) interference in all wireless communications. To be flexible enough to operate worldwide, PAW-1000 system offers a number of frequency ranges. You can choose an appreciate one according to the wireless regulation in your area.Available bands are: UA: 518-548MHz UB: 630-660z UC: 740-770z UD: 800-822z UE: 838-865 MH MH MH MHz To facilitate system setup and protect against RF interference, each system comes with multiple predefined frequency groups and channels. When using a single PAW-1000 system, the operating frequency will generally not have to be changed. In an installation with multiple receiver/transmitter systems, each system must operate on a separate channel. The group and channel system provides an optimum frequency spread when using multiple receiver/transmitter systems. Within a single frequency band, up to 16 individual receiver/transmitter systems may be used in a single installation.

Operational Description

Wireless microphone circuit description of U25PAH-1000 AUDIO CIRCUIT The audio signal is injected via the microphone sensor into the audio circuit composed of the op. amp IC4 （MC4558）, & compandor IC3 （SA571）. The signal is compressed via the compandor circuit at a 2:1 ratio and is pre-emphasized by U2. The level of the output signal is controlled by the resistors R45 (10K VR) and R37, R47 to VCO. MODULATOR CIRCUIT The modulator circuit is a direct FM type built around the local oscillator controlled by Crystal X301(10MHz), VCO(IC302 MCD8825B), PLL(IC301 MB15E03). The modulated output from the oscillator is sent to the RF pre-amp. Frequency Set: The frequency can be chosen by setting switch (AN1) or by an IR sensor and the CPU(IC1 16F73 clock 4MHz). And the signal from CPU to PLL can control the carrier frequency. RF PRE-AMPLIFIER & FINAL AMPLIFIER The 2-stage amplifier, using two transistors Q303(Y7) and Q304(R37), culminating with a normal transmitter output of <1mW. The precious LC output filter (L310-314, C333-342) suppress the output harmonics and matches the output to the integrate antenna. LCD DISPLAY CIRCUIT The LCD display (LCD T4036) is driven by IC5(HT1621) and showing the frequency etc. signals output by CPU. POWER STEADY CIRCUIT Use 2xAA batteries as power supply, Q4 (2SC4081) and Q3 (2SD2098) rise the voltage to 7.5V for audio part, and to U1(7805 5V) for CPU also the LCD, PLL and RF AMP. ANT TYPE: Whip ant Modulation Type： 100KF3E Operational frequency range： 655M—679M Hz
