5 Minute Signal
For the past year and a half, a group based in Ann Arbor, Michigan, named GO-Tech has been formed, uniting individuals interested in creating projects using technology, such as hardware, software, metal, and wood. This initiative is referred to as...
understanding fm transmitter circuit
The electret microphone operates with a current of 200 µA, which varies by ±3 µA in response to sound waves. This variation results in a voltage of 2V across resistor R1 and 4V across the microphone. As sound waves impact...
Sensitive FM Transmitter Bug
This simple-to-assemble FM transmitter can effectively transmit voice signals over an impressive range. By adjusting the trimmer, the signal can be heard on a nearby radio. The transmitter operates within a frequency range of 88-108 MHz and has a maximum...
Circuit diagram 500mW FM PLL transmitter 88-108MHz using LMX3206 and PIC16F870
This oscillator is known as the Colpitts oscillator and is voltage-controlled to facilitate frequency modulation (FM) and phase-locked loop (PLL) control. The transistor T1 should be a high-frequency (HF) transistor for optimal performance; however, in this instance, a common and...
500mW Broadcast FM Transmitter
This compact FM transmitter operates with an RF output power of 500mW and can be powered by a 12-15V battery or power supply. The signal is modulated using frequency modulation (FM) techniques and employs four transistors. The transmitter consists of...
