The first circuit receives the first and second signals, divides the first signal into the third and fourth signals, divides the second signal into the fifth and sixth signals, and adjusts the phase of the fifth signal to obtain the seventh signal, and the seventh and third signals An ...
This is the circuit diagram of aradio transmittersuitable for fitting on radio collars. The circuit transmits a pulse in the FM between band 88MHz to 105Mhz, which can be adjusted. The IC Ne 555 is wired as an astable multivibrator for producing the tone. L1, C3 and Q1 form the modula...
A simple fm radio transmitter circuit which covers frequencies from 88 to 108 MHz. It is built with 3 transistors: BC109, BFR91A and BFR96S. It is quite stable and the output power is around 200 mW. The first stage in a mic amplifier but if you connect this radio transmitter directly...
the 3D irradiation diagram of the dipole Figure 8: The performances of a dipole On air When the circuit is complete and the components are mounted on the PCB, you can switch on the transmitter. With a radio receiver, you can “hear” the swish on the device, at about 7 MHz. Obviously...
