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...
two stage fm transmitter bug more tank circuits
These two tank circuits appear to broaden the operating spectrum. The accompanying information sheet indicates that when both circuit stages oscillate at the same frequency, the power output reaches its maximum. This suggests that if the tunable tank circuit matches...

3 Watt FM transmitter
Connect two 24 V / 3 W bulbs in parallel to the output and set the right frequency on PLL. Now turn on the transmitter. You should tune it on a receiver. Maybe you might stretch coils of the L1....
Coilless FM Transmitter
The RF oscillator employs inverter N2 and a 10.7 MHz ceramic filter to drive the parallel configuration of inverters N4 to N6 via N3. Due to the parallel arrangement of these inverters, the output impedance is low, allowing for direct...
9V FM Radio Transmitter
This is a simple and low-cost FM transmitter circuit. The frequency range of this FM transmitter is approximately 89 MHz to 109 MHz, with an output power of about 9 mW at 9 V. The circuit includes the following components:...
long range stable fm transmitter
This is a long-range stable FM transmitter circuit. The circuit utilizes an LM2950 5V voltage regulator IC in a TO-92 transistor package, which provides a stable 5V to the oscillator until the 9V battery voltage drops to 5.5 volts, ensuring...
