RF Decibel Meter Circuit
A DIY RF decibel (or power) meter is an essential instrument in any radio workshop. However, accurate, wideband models can be quite costly.
A DIY RF decibel meter serves as a valuable tool for measuring the power levels of radio frequency...
RF communication use a sample circuit(example in AVR)
Even including labor, the actual cost of purchasing, stocking, assembly, assembly errors, more expensive PCBs (with additional holes and larger sizes), and the increased difficulty in tuning would likely result in significantly higher expenses.
The analysis of costs associated with electronic...
Jammer circuit
The frequency jammer operates by generating interfering RF noise centered around a 2.45 GHz carrier frequency. As the power of this noise increases, the signal-to-noise ratio of the wireless communication channel decreases, leading to a higher bit error rate until...
Wireless doorbell 300MHz
The operation of a 303MHz circuit has been covered in our project WIRELESS DOORBELL. We are not going over how the circuit works but explain the importance of some of the components and how they affect the range. The most...
RF Signal Attenuator up to 30dB for 1MHz - 500MHz Input
This is a PIN diode-based RF signal attenuator circuit that operates with input frequencies ranging from 1 MHz to 500 MHz. PIN diodes are among the most commonly used components in RF applications.
The RF signal attenuator circuit utilizing PIN diodes...
RF Remote Control With HT12E IC
The following circuit illustrates an RF Remote Control Circuit Diagram. This circuit is based on the HT12E IC. Features include the original data in parallel format, where the decoder IC receives the signal through the RF receiver module, utilizing an...
radio station blocker circuit
This device functions as a reversal of a radio station, sending a null signal to a selected frequency to eliminate the actual broadcast. The radio transmitter operates at a loss of 10,000W; therefore, this circuit is intended for use only...
Modulation monitor
A broad-tuned receiver demodulates the RF signal picked up by a loosely coupled wire placed near the transmitting antenna.
The broad-tuned receiver operates by utilizing a loosely coupled wire antenna, which is strategically positioned in proximity to the transmitting antenna. This...
