Off course a 555 timer can also be used in a receiver, and building transmitters using only discrete components is quite simple, as demonstrated by the 10-minute transmitter and single transistor ...

When Ub = 3.2 V, freq is 30.4 kHz, the top current through each led is 64 mA and total current consumption is 67mA. At this voltage the distance between receiver and transmitter prototype was 13 ...

This transmitter is basic but allows transmission of audio to an AM radio. It consists of an RF oscillator operating in the AM broadcast band, together with a modulator stage, which mixes the incoming ...

The LTC4125 wireless power transmitter improves upon a basic transmitter by providing three key features: an AutoResonant function that maximises available receiver power, an Optimum Power Search ...
