Optimized 6-element UHF Yagi Antenna
The elements diameter of the antenna may vary between 5...8mm and the dipole diameter may vary between 8...12mm (12mm recommended) without the need of changing anything to the length or spacing. All elements except the dipole are electrically connected to...
RF amplifier circuit 1W 2.3GHz MRF2001
RF amplifier circuit diagram, delivering 1W for 2.3GHz, built based on MRF2001. This RF amplifier provides approximately 1 Watt power output with a minimum gain of 8 dB at a 24V voltage supply. The frequency can be tuned from 2.25GHz...
RF Preamplifier Operating in Band 2 VHF Range
The circuit design utilizes a VHF amplifier configured to operate within the frequency range of 88 to 108 MHz, specifically for Band 2 radio applications.
The VHF amplifier circuit is designed to enhance weak radio frequency signals in the specified frequency...
Two-meter preamplifier
This simple, inexpensive, wideband RF amplifier provides 14 dB gain on two meters without the use of tuned circuits.
The RF amplifier described operates within the two-meter band, which typically spans frequencies from 144 to 148 MHz. It is designed to...
VHF TV Signal Amplifier
Many times we needed to strengthen a small signal in the region of VHF or FM. The preamplifier that we propose offers 20dB in all the region of VHF and it still can reach also their 500MHz. The amplifier is...
broadcast band rf amplifier
The circuit features a frequency response from 100 Hz to 3 MHz, with a gain of approximately 30 dB. The field-effect transistor Q1 is configured in a common-source self-biased mode. An optional resistor R1 allows for the adjustment of the...
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...
VHF MODULATOR circuit
Developed as an interface between the General Instruments AY-3-8500-1 TV game chip and the antenna terminal of a TV set. Adjust capacitor C1 to the frequency of an unused channel to which the receiver is set for playing games. The...
RF amplifier and filter for 10.7 MHz
The RF amplifier is similar to the one used in the 2.5 MHz amplifier. At a frequency of 10 MHz, the capacitances of a power MOSFET become significant. Noiseless feedback using transformers is no longer straightforward. Intermodulation and overtones are...
