Amplifiers: Amplifier is a device that accepts a small signal and outputs a larger signal that generally matches the waveform characteristics of the input. Amplifiers are available to boost electrical and optical signals. Device that responds to a small input signal (voltage, current, or power) and delivers a larger output signal with the same waveform features. Amplifiers are used in radio and television receivers, high-fidelity audio equipment, and computers. Amplification can be provided by electromechanical devices. We are exporting Amplifier, RF and an extensive range of both commercial and military rf and microwave amplifiers. People usually talk about stereo components or musical equipments. But this is only a small representation of the spectrum of audio amplifiers. But we have amplifiers all around us in electronic devices.
 
Connectors and Adapters: Connector is a device for joining electrical circuits together. There are various types of connector such as
1. Electrical connector-A device for joining electrical circuits together
2. Audio and video connector
3. Power connector
A connector or switch, which finds the telephone line being called as a result of digits being dialed, it also causes interrupted ringing voltage to be placed on the called line or of returning a busy tone to the calling party, if the line is busy. Our miniature size connectors provides a high density package. The connectors snap together to reduce assembly time. An electronic device, such as a printed circuit board, that enables a personal computer to use additional peripheral devices or hardware.
 
Adapter is a device for matching and properly connecting items, tubing, or devices (especially electric) which are of different size, operating characteristics, or design. It device that enables different sizes or types of plugs, pipes, etc., to be joined.
 
Duplexers: A switching device used in radar to permit alternate use of the same antenna for both transmitting and receiving;. Other forms of duplexers serve for two-way radio communication using a single antenna at lower frequencies. It is a device that combines two or more signals into a common channel or medium to increase its transmission efficiency. Also known as duplexing assembly. A duplexer is also an add on accessory for printers, and it allows one to print on both sides of the paper automatically. An electronic device using sharply tuned resonate circuits to isolate a transmitter from a receiver. Duplexer allows both of them to operate on the same antenna at the same time without the transmitter RF frying the receiver. The common application of a duplexer is to connect a dual band mobile radio’s two antenna connections to a common feed line and antenna. Duplexers are completely different and much simpler to build devices than a repeater duplexer.
 
Modulators: Any device or circuit by means of which a desired signal is impressed upon a higher-frequency periodic wave known as a carrier. The process is called modulation. The modulator may vary the amplitude, frequency, or phase of the carrier. An electronic device used to modulate an electromagnetic wave also offers several high-performance quadrates modulators and demodulators for operation at various frequencies.
