Introductory Overview

Linear-amplifiers- special purpose are a type of amplifiers that are used to amplify an input signal to a larger output. A linear-amplifier-special purpose often has an added feature which allows for increased functionality and adaptability for different applications. The SY88313BLEY-TR is an example of a linear amplifier with special purpose. This article looks at the application field and working principle of this amplifier.

Application Field

The SY88313BLEY-TR is a low noise, broadband differential low noise amplifier suitable for RF and microwave applications. It has a gain of 20 dB with a maximum output power 80 mW across a wide frequency range from 50 - 4000 MHz. Furthermore, it is designed to operate with a supply voltage of 3.3 V and has a very low supply current of 120 mAx12V SWR less than 1.25. In addition to this, it has high stability over temperature, excellent second harmonic suppression (more than 50 dBc) and good return loss. This makes the SY88313BLEY-TR suitable for many types of applications such as radar, satellite communication, automotive applications, low noise amplifiers, distributed amplifiers, phase array based applications, medical applications, base station applications and many more.

General Working Principle

The SY88313BLEY-TR is composed of three distinct stages. Firstly, the input stage serves to provide amplification and enhanced linearity to a given input signal. This is done by the use of active components like transistors, which allow for the input signal to be amplified with minimal distortion. Secondly, the output stage determines the amount of power generated from the amplifier and also helps improve linearity. Finally, the shunt feedback network, also known as the output isolation network, provides isolation and maintains a specific output impedance in order to optimise the device’s performance. This ensures that the SY88313BLEY-TR operates efficiently and effectively.

Conclusion

In summary, the SY88313BLEY-TR is a low noise, broadband differential low noise amplifier suitable for many different types of applications such as radar, satellite communication, automotive applications and many more. The amplifier is composed of three distinct stages, each of which is responsible for its performance. The input stage provides amplification and enhanced linearity, the output stage determines the output power and the shunt feedback network provides isolation and maintains a specific output impedance. This makes the amplifier an ideal choice for many different applications.
