ALM-1812-TR1G RF Amplifiers: Application Field and Working PrincipleRF Amplifiers are an important type of electronic amplifier used in many modern transmitter and receiver systems. This type of amplifier is capable of amplifying signals of radio frequencies spanning across a wide frequency range. The ALM-1812-TR1G RF Amplifier from China is one such interactive product, used in a number of applications such as military and automotive. This article will explain its various features, application fields, and its working principle. Features of ALM-1812-TR1G RF AmplifierThe ALM-1812-TR1G RF Amplifier is an ultra-compact and robust amplifier, with a series of remarkable features. It provides reception to signals of radio frequencies ranging from 835 to 2180 MHz. The amplifier module provides a cased gain range of 14 to 19dB and a noise figure of 4 to 8 dB with a linear gain of 30 dB. It has a maximum power output of 31dBm and a power consumption of 6W. This amplifier is made of a robust, segmented aluminum housing, with an IP 67 grade of water and dust protection. It also comes with a protection circuit for temperature and current, and is ideal for use in tight spaces. Application Fields of ALM-1812-TR1G RF AmplifierThe broad range of ALM-1812-TR1G’s features makes it suitable for use in many application fields. It serves many military and automotive purposes, like for instance, the monitoring or enhancement of the signals for navigation and communication. It can play an important role in multimedia applications such as digital radio broadcasting, surveillance, wireless LANs, microwave links, and medical imaging systems. It is also commonly used in television receivers, satellite transmitters and receivers, as well as in cellular communication systems. The Working Principle of ALM-1812-TR1G RF AmplifierThe ALM-1812-TR1G RF Amplifier operates based on a two-stage circuit, based on the low noise preamplifier (LNA) and a power amplifier. It gets the input signal from the antenna and sends it to the pre-amplification stage. In this stage, the signal power is increased, and the signal is then sent to the power amplifier stage. Here, the signal power is further increased and then the signal is sent to the output.In the first stage, the signal passes through a low-noise preamplifier, which increases the signal strength. This is achieved by amplifying the signal with a gain of 20-22dB. The output from this stage is then sent to the power amplifier stage, in which the signal is further amplified with a gain of around 30dB.The preamplifier is designed to sustain low noise, so that it does not affect the quality of the output signal. It is also designed to provide a linear response, as well as the attenuation of unwanted noise components. The power amplifier also provides excellent performance, with linear response and power delivery of up to 31 dBm. In conclusion, the ALM-1812-TR1G RF Amplifier is a powerful and reliable module capable of amplifying signals of radio frequencies within the range of 835 to 2180 MHz. It has a wide range of applications, from military and automotive to multimedia and cellular communication systems. It functions on two stages, namely the preamplification and the power amplifier stage. The preamplifier increases the signal strength, whereas the power amplifier increases the signal strength further and provides the required output signal.
