Amplifier

The bandwidth of an amplifier is the range of frequencies for which the amplifier gives "satisfactory performance". The definition of "satisfactory performance" may be different for different applications. However, a common and well- accepted metric is the half power points (i.e. frequency where the power goes down by half its peak value) on the output vs Efficiency is a measure of how much of the power source is usefully applied to the amplifiers output.

 

 

Low Noise Amplifier

Low-noise amplifier (LNA) is an electronic amplifier used to amplify very weak signals (for example, captured by an antenna). It is usually located very close to the detection device to reduce losses in the feed line. This active antenna arrangement is frequently used in microwave systems like GPS, because coaxial cable feed line is very Iossy at microwave frequencies, e.g. a loss of 10% coming from few meters of cable would cause a 10% degradation of the signal- to-noise ratio (SNR).

Gain RF Amplifier

The gain or an amplmer IS the ratio to output to input power or Amplitude, and is usually measured in decibels. (When measured in decibels. it is logarithmically related to the power ratio: G(dB)=10 log(P.,m /(P,-,,)). RF amplifiers are often specified in terms of the maximum power gain obtainable, while the voltage gain of audio amplifiers and instrumentation amplifier will be more often specified (since the amplifier's input impedance will often be much higher than the source impedance, and the load impedance higher than the amplifier’s output impedance).

Power Divider & Combiner:

Power Divider

Power dividers are passive devises used in the field of radio technology. They couple part of the transmission power in a transmission line by  a known amount out through another port, often by using two transmission lines set close enough together such that energy passing through
one is coupled to the other.

In the field of microwave engineering and circuit design, the Wilkinson Power Divider is a specific class of power divider circuit that can achieve isolation between the output ports while maintaining a matched condition on all ports.

 

 

Power Combiner

The Wilkinson design can also be used as a power combiner because it is made up of passive components and hence reciprocal. First published by Ernest J. Wilkinson in 19601H. this circuit finds wide use in radio frequency communication systems utilizing multiple channels since the high degree of isolation between the output ports prevents crosstalk between.the individual channels.

GSM Repeaters

The repeater system is a two-way amplifier that receives signals from one antenna, amplifies them and transmits through the other antenna in order to antenna, amplifies them and transmits through the other antenna in order to provide booster performance to extend the coverage of radio communications in buildings, basements and other RF shadow areas. Features such as high linearity amplifier characteristics, and sharp out of bandrejection duplexers, assist in avoiding interfering signals 8 makes it an ideal solution for in-building installation.

 

 

 

 

 

Synthesizer

Here we are using 3 Synthesizer Modules as given below.  

        CTW1690PES
        CTLP4430HFA
        CTLP102.40HDA  

LO-1 is the broad band output frequency from 4520 MHz to 7500MHz.  We cannot generate total band with one PLL module. So we can use VCO from 1130MHz - 1875MHz and it will be connected to X4 multiplexer. It will generate total band.  LO-2 is the single output frequency of 4430 MHz using single VCO. ADC Clock is the single output frequency of 102.4 MHz using single VCO.
