M3000 golden phoenix is a display board for m3000 high frequency module of a mini walkie-talkie from mc devices. With m3000 golden phoenix, main functions of walkie-talkies could be realized.
Main functions
Frequency: any frequency point within 315mhz-385mhz or 390mhz-470mhz
Power: 0.5w--1w(test voltage: 4.2v); 2w(test voltage: 7.4v)
Receiving sensitivity: <-120dbm
Ctcss code: 38 codes
Scanning function(scan)
Automatic squelch function
Lcd indicator, tx, rx indicator
Digital volume regulation (8 scales)
5 calltone for selection
Key beep
Transmission-completed beep
Sound output of speaker and headphone for selection
Sleep mode
External mcu interface (further software assistance is available)
The high-frequency module is used exclusively for uhf wireless mic. With audio circuit, transmitting module (tx) could be made into a complete wireless speaker or belt-pack transmitter. Receiving module (rx) consists of noise amplification, one time frequency mixing, twice mixing, local oscillation, mcu frequency control and other functions. With audio circuit, it could be made into a complete wireless mic receiver. By applying d2008 directly, factories could simplify design and production of uhf wireless mic, and adopt the module easily in mining industry and electronic consumer system equipments.
D2009 may be applied in low-cost uhf and vhf wireless mic. With multiple frequency points pll, it may replace widely used single frequency point crystal in the market, and be easily embedded in wireless voice transmission and amplification in mining industry and electrical consumer systems. Together with audio circuit, transmitting module (tx) may be made into a complete wireless speaker or belt-pack transmitter. The receiving module (rx) is characterized by noise amplification, frequency mixing, local oscillation, mcu frequency control and other functions. Together with audio circuit, it may be made into a complete wireless mic receiver.
M3000 high-frequency module has two types: m3000a and m3000d, with different frequency band. The module consists of transmitting voice signal, modulation, power amplification, noise amplification, voice signal demodulation and signals procession. It begins to work normally by simply adding an external mcu, an audio amplifier, a mic (microphone) and a speaker.
The module is with small volume. It is easy to develop within short period. It could be made into small walkie-talkie, and be used in other mobile handheld devices. It is practical and easy to use, and may be widely used in gifts, catering, tourism and other industries.
M3000 silver phoenix is a mini walkie-talkie module developed by mc devices. Its size is as small as 31.75mm (length)x 20.828mm (width)x 6.5mm (height). A walkie-talkie is made by simply adding external speaker and power. The front side of m3000 silver phoenix is control board equipped with mcu, and its back side is m3000 high frequency module.
M3000 silver phoenix may be easily embedded in a variety of portable devices, and work as walkie-talkies, which are widely used in tourism, hotel service and gifts. The easiest way is to fix a channel directly on the board, and connect a speaker and power. For more complicated application, channels selection and volume regulation may be achieved by simply adding a dip switch.
Main functions
Frequency:: 4-32 frequency points are randomly selected within 315mhz-385mhz or 390mhz-470mhz (occupying 2-5 i/o ports)
Power: selected between 0.5w-1w(test voltage: 4.2v)
Receiving sensitivity: <-120dbm
Ctcss code: 0-8 selectable codes (occupying 0-3 i/o ports)
Volume regulation: 2-4 scales may be set by external dip switch (occupying 1-2 i/o ports), and the default set is the lowest volume.
Automatic squelch function
Tx, rx indicator
Sleep mode
No jarring sound after ptt call (standard function)
Notes:: there are only 5 i/o ports in silver phoenix mcu, so customers should select ports reasonably.
