fm schematic | Next Electronics

This circuit is a wideband signal strength meter designed to respond to small variations in RF energy within the VHF spectrum. It is capable of detecting AM or FM modulation as well as a simple carrier wave. The circuit measures...

RF Remote Control Encoder and Decoder Chips Explained

Creating a universal remote control system has become quite straightforward. One can acquire the necessary chips, assemble them, and the high-tech remote control device will be operational. This document discusses specific remote control chips designed for this purpose. The IC...

SA2132 AM/FM RADIO RECEIVER

The SA605 is a high-performance monolithic low-power FM intermediate frequency (IF) system that integrates a mixer, oscillator, two limiting intermediate frequency amplifiers, a quadrature detector, muting, a logarithmic received signal strength indicator (RSSI), and a voltage regulator. It combines the...

rf remote control encoder and decoder

This document explains two RF 433kHz remote control chips specifically designed for remote control applications. The IC TWS-434, along with its encoder chip HT-12E from Holtek, forms a high-quality transmitter circuit, while the chip RWS-434, paired with the decoder IC...

Video/Audio Wireless Transmitter

In this fast-paced world, there is little time for inconveniences and a greater need for portability and adaptability. The idea for an Audio/Video transmitter stems from this need. There may have been times when you’ve wanted to hook up your...

10M Dsb Qrp Transmitter With Vfo Circuit

The three schematics illustrate three building blocks for a 10-meter SSB transmitter. These blocks can also be utilized independently as circuit modules for other transmitters. The VFO board incorporates an FET transmission oscillator, with the VFO signal being mixed in...

Visual modulation indicator

The brightness of the indicator lamp changes in accordance with the modulated RF signal. Adjust resistor R2 while the transmitter is on (modulated) until the lamp flashes in sync with the modulation. Cl = 5 pF, C2 = 100 pF, Dl...

Projects

This project was inspired by a desire to create something unique rather than with the expectation of it becoming a practical transmitter. At the time of writing, the project is in the breadboarding phase, and a decision has yet to...
