RF amplifiers fall into the category of devices used to control electrical signal amplification in radio frequency (RF) systems. The MGA-83563-TR2G is one of the most popular RF amplifiers on the market today. In this article, we’ll take a closer look at the application field and working principle of the MGA-83563-TR2G.

Overview of the MGA-83563-TR2G

The MGA-83563-TR2G is an RF amplifier from Avago Technologies that is commonly used to boost RF signals in wireless communications networks. It is a high-gain amplifier designed for use in a wide array of applications, including cellular base station infrastructure, repeaters, mobile and portable applications, global positioning, and satellite communications systems. The amplifier can also be used for cable TV and general-purpose broadband operations. It features very low noise figures, with a maximum gain of 33 dB. Additionally, the amplifier operates over a wide temperature range from -40°C to 90°C and has an integrated negative temperature coefficient (NTC) thermistor for temperature protection.

The Working Principle of the MGA-83563-TR2G

The MGA-83563-TR2G operates according to the differential amplifier circuit which is one of the most common RF amplifier topologies. A differential amplifier is an arrangement of two transistors (or more) connected in such a way that the output current is determined by the voltage difference between two input signals. In the case of this RF amplifier, it is the input current which is determined by the difference between an input voltage and a bias-signal. The output voltage is determined by the relationship between the two input signals.

The MGA-83563-TR2G has two main components: the input stage and the output stage. The input stage is composed of two transistors, while the output stage is composed of one transistor. Both stages are arranged in a differential configuration such that the output is determined by the input voltage difference between the two transistors in the input stage. The gain of the amplifier is determined by the transistors’ transconductance parameter.

The amplifier also has two additional components: an emitter-follower stage and an active load circuit. The function of the emitter-follower stage is to provide impedance matching between the input stage and the output LED. This helps minimize any distortions in the signal as well as improve the signal-to-noise ratio. The active load circuit is used to provide the gain of the amplifier and to ensure that the device remains stable over a wide range of input levels and frequencies.
