80 Watt FM Stereo Transmitter
2008-08-07 09:23:00 This transmitter circuit was designed from the ground up to provide very high sound quality, coupled with excellent frequency stability, reliability, etc. It can be used as a standalone transmitter to serve a medium-sized town, or as an exciter to drive a kilowatt-class power amplifier to serve a large city. It is designed to work from 13.8V nominal voltage, so that it can be run from a common communications power supply in parallel with a backup battery. In the event of a power cut, the transmitter can keep operating from the battery, at slightly reduced power as the voltage drops. It consists of four modules, the three most important of which are ready, tested, and described below. The fourth module has not yet been built, and might never be built, but I will describe its basic functions so that you can design it, if you want. The audio processor and stereo encoder The textbook way of processing and encoding a stereo signal for FM transmission goes like this: 1) Take both chann...

Crystal-Based FSK Transmitter RF9901
2008-05-24 20:50:00 The RF9901 is an FSK transmitter that can be used to transmit FSK data using an RF carrier frequency in the range of 400MHz to 930MHz. This device is intended for and ideally suited to both European and United States ISM band applications. The RF9901 evaluation board (RFMD Part Number RF9901PCBA) utilizes a Colpitts oscillator to generate the reference frequency for the PLL phase detector. The PLL consists of an integrated voltage controlled oscillator (VCO), a divide by 32 prescalar, and a reference frequency oscillator amplifier. The output carrier frequency is then the reference frequency multiplied by 64.Which Topology?The Colpitts oscillator is only one of many types of oscillators that could have been used and was chosen primarily for its low parts count. Other oscillators have various tradeoffs for the designer which may result in choosing another oscillator type.This article does not delve into oscillator design, but is simply to provide assistance in understanding why the ...

A Small FM Transmitter With Loop Antenna
2008-05-16 22:05:00 This small Low Power FM transmitter with Onboard Magnetic Loop Antenna that designed by Radio Morningstar. It's suitable for home fm broadcasting. As seen on YouTube Page.This is the PCB board layout for a small LPFM transmitter that i'l showed on Youtube. This new design is even more powerfull, using 4 instead of 2 transistors. The range will go up to 2 kilometers or even 4 - 7 km using een external twinlead fed 300 ohm folded dipol antenne. Or use just 2 transistors for less range using a 100 Ohm Emitor resister instead of the 33 Ohm for lower battery consumption.Take good notice by placing the transistors , for the BF 199 the connections are 1 Basis 2 Emittor 3 Collector. One set transistors is placed 180 degrees backward , be sure all the collectors are connected at the antenna loop.

Miniature Telemetry Transmitter Applications
2008-04-20 23:49:00 IntroductionThe goal of this project was to build a small, cheap, light-weight telemetry transmitter to attach to a small bird.Specifically:* Telemetry Tranmission should be tuned to the 2-meter band.* Battery life in the field should exceed 3 months without replacement.* Range should be 500 meters.* Weight less than 10 gramsThe CircuitThis wireless telemetry transmitter circuit shown was originally designed by William Cochran (1), with modifications by Charles Walcott. Physical layout of the circuitA test version of the circuit was constructed in a 5x2 chunk of IDC female header plug so that the crystal and transistor could be easily changed. The tank coil can be seen on the right in either photo below. The brown/white wire to the right is the antenna. Power supply leads extend to the left.The final circuit version of telemetry application was built using the crystal as the physical substrate.Reference1. William W. Cochran; Rexford D.

Telemetry Transmitter
2008-04-20 23:36:00 Telemetry or "remote measurement" is a highly automated communications process by which measurements are made and other data collected at remote, inaccessible or dangerous places, and then relayed by a telemetry transmitter to receiving stations for display, monitoring, and recording. The original telemetry systems were termed "supervisory" because they were used to monitor electric power distribution. Communication channels form a major part of any telemetry system, as it involves measurement of the transmission of data over various mediums.Telemetry transmitter is the instrument used for recording the readings of an instrument and transmitting them by radio or wireless frequencies. Technically, when relaying data, it is necessary for the transmitter to identify the data item corresponding to each segment of the bit stream. This is done by inserting a synchronization bit string into the telemetry stream on a regular basis, usually at the beginning or end of each repeating cycle. Th...
