Description: Fixed 144/100/76/74/72/50/36/27 MHz frequency Transmitter with FM Modulation Device is Built on Motorola IC MC2833 and packed in Alluminum Case For frequency stability a high quality Quartz Resonator is used To increase the frequency of deviations to +/- 8 kHz a frequency multiplication is used The 7th order Bandpass filter is used to suppress Spurs and Harmonics High quality components are also used to ensure a clean Spectrum up to -60dBc Device is suitable for Ttransmitting Analog Signals as well as Digital FSK Transmitter can be used in conjunction with external Antenna Main Features: - Carrier Frequency - 144/100/76/74/72/50/36/27 MHz (optional) - Input Modulation Signal level (maximum) - 10 mVrms - Deviation Frequency - +/- 8 kHz - Frequency Range of the Modulation Signal - 20-10000 Hz - Power Supply Voltage - 3-9 V - Power Connector dimensions - 5.5x2.1 mm jack - Output Power (at 9 V) - 0dBm - Transmitter dimensions - 50x50x15 mm - Case material - Alluminum - External Antenna - mountable (not included) Frequency multiplication: We produce our FM Transmitters using multiplication of the Frequency method. This allows to achive quiet wide deviation with Frequency. For example for output Frequency of 144 MHz we multiply 12 MHz Crystal for 12.
