PLL FM Transmitter using LMX1601 ATtiny2313 AT90S2313
This document describes a PLL FM transmitter utilizing the LMX1601 and either the ATtiny2313 or AT90S2313 microcontrollers. A common feature of previous low-power FM transmitters developed over the years is that their operating frequency is determined by an LC resonant...
MAX2620 10mhz To 1050mhz Integrated Rf Oscillator With Buffered Outputs
The MAX2620 integrates a low-noise oscillator with two output buffers in a cost-effective, plastic surface-mount, ultra-small uMAX package. This device combines functions that are typically achieved with discrete components.
The MAX2620 is designed for applications requiring precise frequency generation with minimal...
Simple TV Transmitter circuit diagram (VHF)
Many individuals inquire about TV transmitters. This document provides a useful circuit diagram that enables signal transmission over distances of 75 to 100 meters. The circuit diagram is not original but was provided by a colleague. Contributions of circuit diagrams...
Metal detector 8
This example describes a metal detector that employs a PLL (phase-locked loop) digital integrated circuit, the MCl4046. It emits an alarm signal upon detecting metal objects and can identify the type of detected material based on the current meter's readings....
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...
Frequency signal tracking circuit (PLL circuit) composed of CD4046
A frequency signal tracking circuit is implemented using a phase-locked loop (PLL) configuration, which is a fundamental application of the CD4046 integrated circuit. The circuit, illustrated in the accompanying chart, utilizes the CD4046 to form a PLL that effectively captures...
pll fm demodulator
This circuit is a Phase-Locked Loop (PLL) system designed to function as an FM demodulator. The output of the Voltage-Controlled Oscillator (VCO) tracks the FM signal, and since the input voltage of the VCO is proportional to its output frequency,...
4-18Mhz-converter
The unit consists of an RF amplifier Q1, a local oscillator Q2, and a mixer Q3. The two frequency bands are covered without a band switch by utilizing an intermediate frequency (IF) of 3.5 MHz. The oscillator operates within a...
Test Signal Generator
This signal generator uses a three channel DAC to generate Composite video signal (CVBS) and S video signal (Y/C separated) at the same time, left one channel is not used in NTSC format. It is assigned for one of the...
