Specification: * Launch distance: 50-300 meters * Modulation mode: double track FM stereo (factory default is set at 107.9 MHZ) * Stereo degrees of separation: 45 db * Frequency stability: PLL phase-locked loop (no frequency drift) * Dimensions: length 6.5 CM 3.9 CM high 1.3 CM wide * Working voltage: DC 5-6 v (mobile power supply noise big, it is recommended that the battery) * Working current: about 200 ma * The power output: a maximum of 500 mw * Transmission frequency: 87.7 to 107.9 Mhz * Frequency adjust: dial the code switch * Audio response: 40-1500 hz * Signal-to-noise ratio: 50 db or higher * Antenna connection mode: wire welding * Rf output impedance: 50 euro * Carrier frequency deviation: allowed + 500 hz * Modulation capacity: > + 100 KHZ * The parasitic amplitude modulation noise: 50 or less * Harmonic distortion: + 75 Hz frequency offset < 1% plus or minus 100 Hz frequency < 1% * Rated frequency deviation: + 75 KHZ modulation (100%) * Ambient temperature: - 10 to + 40 * Direct manufacturers, to avoid the difference * The module using traditional PLL BH1417 PLL chip production, so the work is very stable, even if the human touch antenna will not cause the change of frequency module, can be used safely for a long time.
