Analysis of Radio System Components and Different Types of Mixers

This assignment provides a detailed overview of radio system components, including power, oscillator, modulator, amplifier, and antenna at the transmitter end, and antenna, tuner, detector, and audio amplifier at the receiver end. It elaborates on different types of mixers, such as switching mixers, analog mixers, diode ring mixers, frequency mixers, electronic mixers, and RF mixers, explaining their functions and applications in telecommunications. The assignment includes references to support the explanations and provides insights into how these mixers are used in intermediate stages to mix different kinds of signals and modulate the desired output.

Answer to question 2
Different components of a radio system are power, oscillator, modulator, amplifier
and antenna at the transmitter end (Mishra & Alexander, 2018). On the receiver end the
components are antenna, tuner, detector and audio amplifier.
Different types of Mixers are (Algumaei, et. al, 2017):
 Switching mixer- It is used to mix two input signals to produce the output. It focuses
on obtaining a result which has high linearity, no noise and has a good response in
terms of polarity switching.
 Analog Mixer- It is required to produce an analog output using some input signals,
thus analog mixer mixes two signals and produces an output in analogy to emphasise
the digital operation (Shirai, 2017).

 Diode Ring Mixer- It was basically used to implement high performance and also
enables switching operations (Chaturvedi, Kumar & Meena, 2014).

 Frequency mixer- It an electrical circuit that is used to create new frequency from the
existing frequency.

 Electronic mixer- When there are two or more electrical signal in the network,
electronic mixer mixes the signal and form a composite output signal.

Thus there are various mixers available in the telecommunication and basically it is used in
intermediate stages to mix different kind of signals and modulate the desired output.
 RF Mixer- It is a mixer that is used to convert a signal from one frequency to another
frequency mixer. It can be either used to modulate the signal or to demodulate. It
basically has three ports one is local oscillator input and other is radio frequency (RF)
input which in turn produces an intermediate output with the desired frequency.
