SENSITIVE RF VOLTMETER
This schematic illustrates a peak-reading diode voltmeter that is powered by two amplification stages. A 100 µF capacitor is utilized to create a substantial time constant, which ensures effective damping of the meter. The restricted differential output voltage, combined with...
Wireless Headphones Transmitter Circuit
This wireless headphones transmitter ensures quality reception over a distance of 2 meters. The oscillator frequency ranges from 1750 kHz to 3500 kHz, and for the antenna, it...
The wireless headphones transmitter operates within a frequency range of 1750 kHz to...
Remote control transmitter circuit
The circuit composition of a specific remote control transmitter is illustrated in a diagram. The transmitter primarily consists of a large-scale integrated circuit chip (D1, THBT-T01), a 4.5 kHz crystal oscillator, a 32 kHz crystal oscillator, a liquid crystal display...
All Transmitter & Receiver schematics
This website was developed to assist students in discovering ideas for their projects or final year projects (FYP). All content presented here is sourced from reliable blogs, websites, and forums. The owner of this website assumes no responsibility for any...
Rf-Type Battery Charger Circuit
This type of charger transfers RF energy from an inductor (L2) to an external pickup coil. The pickup coil is connected to a rectifier and a battery that requires charging. This design is advantageous as it eliminates the need for...
Simple Rf Test Oscillator Circuit
A simple oscillator for intermediate frequency (IF) alignment at 455 kHz can be useful in field testing or in scenarios where a standard signal generator is available. The inductor (L1) should resonate at the desired output frequency with the series...
active short wave antenna
The circuit presented illustrates that despite the availability of various new components and technologies, it remains feasible to design useful and interesting circuits. The circuit utilizes two well-established transistors, the BF256C and the BF494. Along with the necessary resistors and...
The ATL-3 Loop Antenna
All ATL-3 loop windings are centre tapped and balanced w.r.t. their amplifier/receiver chassis ground, and therefore electric field interference pick up tends to self cancel. Magnetic noise fields, e.g. televisions and the electric meter box, or electromagnetically radiated interferences, may...
Transmitter Negative Key Line Keyer
Using an NTE288 (or ECG288, GE223, or SK3434), this circuit can key a negative line up to -300 V maximum. Do not use this circuit to key a vacuum-tube amplifier that draws grid current because the keying transistor might be...
