Fm
Product description:

Shape size: 2 cm x 1cm

Working voltage: 2v-9v (Recommended electricity from batteries, there will be acoustic sounds in stabilizing power sources)

Voltage impact distance, the lower the voltage, the closer the distance

Working current: 9ma (3v voltage test, saving electricity)

Reference distance: Open 100 m, indoor barrier environment 10-30 m (3v voltage test, increase voltage distance greatly)

Frequency of work: 85mhz-115mhz (The onset default frequency is usually between 99 and 101)

Mode of receipt: As long as 88-108 mhz fm fm radio can be received, with fm functional mobile phone.

Frequency regulation: Adjustable capacitance

Output impedance: 50 ohm

Scope of application: High sensitivity wireless microphone, wireless recordings, wireless listening, maternal and child care、 patient care, etc. Strictly prohibited for wiretapping purposes, it 's illegal!!

This module is a new miniature patch fm launch module, better pcb process production, small size, easy to load in coarse barrel、 inside lighters, etc. The frequency stability generated by the module can be received on radio, use of digital radios in particular, it works better. All components use brand devices

Please reassure buyers of quality, buyers need to weld power and antennas themselves.

The mode frequency stability of local vibration circuit with high frequency head of black and white tv set is adopted in the module internal vibration circuit, not the ordinary capacitance three-point oscillator can be compared to the one that can be compared with that of the ordinary capacitance three-point oscillator circuit., there will be no frequency drifting even if the antenna of the hand grab module is tested by myself. 200 mhz, the rf output impedance of the module is 50 ohm convenient module directly and amplifier matching is more suitable for the needs of diy

Module power supply voltage at 3v, launch distance is about 100 m in an open environment, the average indoor environment is about 20 meters away, the higher the voltage, the farther the distance, the 9v voltage can be emitted up to 300 meters, antennas can be used in the average conductor antenna of about 75 centimeters long and must be straightened when used, the test results are better using pull rod antennas Of course, a shorter antenna can also be used as a reference to specific recommenda
