ATV JR TRANSMITTER 440 MHz
This low-power video transmitter is suitable for remote control applications, surveillance, or amateur radio. It employs seven transistors within a crystal oscillator multiplier RF power amplifier chain, along with a high-level video modulator. A supply voltage ranging from 9 to...
tv transmitter circuit
Here is a simple schematic of a TV transmitter circuit, or video transmitter circuit, capable of broadcasting in the VHF range from 60 to 200 MHz. The input video source can be any CCD camera or VCR. The output power...
the design of the intellectual wireless signal transducer of ARM
The intellectual wireless signal transducer is designed for major transducer applications and typical sensor output signal designs. It is essential to first analyze the outgoing signals from the transducer. Typically, the output of the transducer is a standard electric current...
Video to RF Signal Conveter
This circuit is a RF modulator which can be used for modulating of video signals. The P1 controls the Light and the P2 controls the contrast of video signal. The RF modulated output signal can be received on the VHF...
Remote Operated Spy Robot Circuit
A remote-operated spy robot circuit can be controlled using a wireless remote controller. It captures audio and video information from the surroundings and transmits this data to a remote station via RF signals, with a maximum range of 125 meters,...
RF MODULATOR
Two integrated circuit (IC) RF modulators are utilized to convert a suitable baseband video and audio signal into a low VHF modulated carrier, specifically channels 2 through 6 in the U.S. and channels 1 through 3 in Japan. The modulators...
VHF antenna amplifier circuit diagram
This RF antenna amplifier is designed for high frequency and VHF bands (for radio and TV) and provides a gain of 22 dB. The amplifier features very low noise, measured at under 1.6 dB. The L1 coil has a value...
Low Power Wireless Audio Power Amplifier as baby mointor
This appears to be an infrared (IR) transmitter. IR signals do not penetrate walls, and it is assumed that this device is intended for use in a room separate from the one in which the user is located, rendering it...
Wireless am microphone
The transistor Q1 and its associated components form a tunable RF oscillator. The RF signal is directed to transistor Q2, which functions as the modulator. Operational amplifier IC1 amplifies the audio signal and transmits it through resistor R4 to the...
