500mW PLL FM transmitter 88 108MHz

Circuit diagram 500mW FM PLL transmitter 88-108MHz This PLL transmitter is controlled and the frequency is very stable and can be programmed digitally. Transmitter will work 88-108 MHz and output power up to 500mW . With a small change can set the frequency of 50-150 MHz . The output power is often set to several watts with transistors. So therefore I decided to build a simple transmitter with great performances. The frequency of this transmitter can easily be changed by software and space / compress air coil. This transmitter is the oscillator colpitts. Oscillator is a VCO (voltage controlled oscillator) which is set by the PLL circuit and PIC micro controller. This oscillator is called the Colpitts oscillator and voltage controlled to achieve the FM (frequency modulation) and PLL control. T1 must be HF transistors to work well, but in this case I use a cheap and common BC817 transistor. LC tank oscillator needs to oscillate properly. In this case the LC tank consists of L1 with t

TL496 3 to 9 volt converter Circuit Diagram

This is simple Simple TL496 3 to 9 volt converter Circuit Diagram . it uses the TL496 power supply controller, a coil and a electrolytic capacitor. The maximum output voltage is actually 8.6V and current is around 80mA.The input current (the current drawn from the batteries) is 405mA at the maximum output current. Without load the current consumption is 125µA and the batteries life is around 166 days. TL496 3 to 9 volt converter Circuit Diagram

Rechargeable battery backup circuit for Smartphone using MC34063 IC

Hi all, Chip long time no post anything interesting, is to learn the IC mc34063, to earn share posts made redundant charging circuit for Smartphone Post to share your research and learn, how people do How? Do not by Chip circuit design should not ensure stability chay.Chip not resolve complaints when the circuit xoet xoet offline ^^ Illustrations Product I. Charging circuit diagram mc34063 Step up Surely many of you see the status of the battery for Smart Phone. In this symposium to share their phone charger circuit can pocket for your phone. I wish you well done it this circuit .... Summary: Battery power circuit: Lion Battery, cell laptop batteries, or simply your phone. Charging Connectors: USB Compatibility: Android, Windows Phone, iOS devices .... support charging via USB port (in addition to the user terminal connector jack like Nokia ....) Performance: 85% Current consumption: max on 1A (rechargeable good for Tablet) Left Heart: IC mc34063 Circuit pri
