CNN has been popular, but because of the limitations of its lines , so that some users are not always high-quality signal , so that TV image signal less than ideal . I use a small amount of components made ​​of a small, easy to use cable TV amplifier

9800 Series UHF transmitter unit is more commonly used in CATV trunk amplifier module for doubling the output power transmission equipment equipment. Practice has proved that either Motorola or Philips with the module , the effects were just as good

Implemented by the Min-Micro Technology Research MEC002A efficient wireless sound transmission module is small, the RF output power, the sound sensitivity is high, the output frequency is relatively stable, etc., use it to form the FM transmitter cir

First, the principle and function of plant maintenance Diagram as shown below, the figure, K, Kl ~ K10 are small toggle switch. Kl ~ K4 provides power operation of the corresponding analog signal is sampled, the corresponding green indicator light V

This circuit is a simple two transistor (2N2222) FM transmitter. No license is required for this transmitter according to FCC regulations regarding wireless microphones. If powered by a 9 volt battery and used with an antenna no longer than 12 inches

The figure is from the introduction of an electronic magazine on a regular transistor 3DA87C to make use of long-range FM transmitter circuit , the circuit is an ordinary three-point oscillator circuit , the article shows that the long-distance trans

You do not look this amplifier is simple, if you go to test the latter , after you really surprised to find it very effective . Here is the schematic of this amplifier circuit : 图1 From the circuit diagram can understand , this amplifier is the ou

Outline This is a small , but quite powerful FM transmitter , three with better audio modulated RF preamplifier stage . T has 4 watts of output power and 12-18 VDC , which makes it easy to carry . Technical Specifications - Features Modulation type
