UHF amplifying circuit diagram
The circuit depicted in the figure operates within a frequency range of 400 to 850 MHz, designed as a UHF amplifying circuit. For optimal performance and results, it is recommended that the circuit be manufactured using silver-tin processing techniques.
The UHF...
loop antennas
A loop antenna is a radio antenna made up of a loop (or loops) of wire, tubing, or other electrical conductor with its ends connected to a balanced transmission line. This design includes two distinct types of antennas: the small...
ATL-3 Loop Antenna
This antenna is the result of long term development and user feedback. 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,...
ATA5423 ATA5423 UHF Transceiver For ASK And FSK Systems 315 MHz
The ATA5743 is a multi-chip PLL receiver device housed in an SSO20 package. It has been specifically designed to meet the requirements of low-cost RF data transmission systems, supporting data rates ranging from 1 kBaud to 10 kBaud using Manchester...
Simple UHF oscillator
This oscillator is typical for operation between 350 to 500 MHz. The microstrip inductor is implemented as a printed circuit board (PCB) trace. The output power ranges from 55 to 100 mW into a 50-ohm load, with frequency stability typically...
DIY 100mw TV Transmitter Printed Circuit Board (PCB)
The circuit design philosophy allows for debugging without any RF instruments. Although its performance may not match that of professional equipment, it should be adequate for hobbyists, with audio-visual transmission effects comparable to general-purpose machines. The transmitter consists of two...
The K9AY receiving loop antenna
A K9AY antenna system and controller has been designed with the intention of creating a more effective unit at a lower cost compared to commercially available versions. The K9AY antenna features a steerable null, maintaining a gain close to unity,...
TV Video Transmitter
This device is a TV transmitter designed to transmit video signals from various sources, including video cameras, satellite receivers, DVD players, and game consoles. The TV transmitter operates within the frequency range of 470-580 MHz and can be received on...
Two Homing type Direction-Finding
The antenna consists of two vertical dipoles. Diodes in each dipole allow the circuit to select which antenna is active at any given time. When a positive voltage is sent up the coax feedline, diode D1 conducts and D2 blocks,...
