This transmitter works, radio frequency range with a wideband frequency of 40 MHz.So you can use this with lots of electrical equipments





The schema is consuming a total of 7 mA of current while the gain is in the measurement of 20 dB. All these values are due to the presence of a 12 V up to 15 V DC supply. The input and the output of the schema are designed to be compatible with coaxial cables with complex resistance of 75 Ohms.
