UHF TV Antenna Booster
This is the circuit diagram of a UHF band TV antenna booster with a 15dB gain power. This low-cost antenna booster is simple and easy to build. This circuit is based on the BF180 UHF transistor. The first stage is...
RF wireless allarm magnetic switch PIC16F84
This circuit was formed to create a wireless alarm from a normal magnetic contact. By fixing the magnet to the leaf of a door, or swing of a drawer, it is easy to reveal the opening. To transmit the signal...
RF circuits
A field strength meter utilizing a biased Schottky detector employs a temperature-compensated Schottky diode within an amplified, untuned field strength indicator powered by two AA cells. This device indicates the relative field strength of RF fields ranging from a few...
UHF Antenna Booster
The UHF antenna booster is designed to enhance signal reception, particularly in areas that are distant from TV stations or relay transmitters. This booster operates within the frequency range of 400 to 850 MHz.
The UHF antenna booster functions by amplifying...
Uhf Motion Detector
The UHF motion detector operates on the Doppler radar principle. Q1 is an oscillator that creates a radiated signal. An object in the radiated field reflects some of this energy back to the detector. If the object is moving, the...
High Frequency Colpitts Crystal Oscillator
Op-amps have been widely used in low-frequency oscillators.
Op-amps, or operational amplifiers, are versatile components frequently utilized in the design of low-frequency oscillators. These devices are capable of generating periodic waveforms, such as sine, square, or triangular waves, which are essential...
Basic RF Oscillator
Create a basic RF oscillator. The circuit is very simple, so complex calculations will be omitted, and component selection will be simplified using calculators. For this example, the target frequency is 7 MHz. The circuit includes a transistor (TR1) on...
