RF Amplifiers

ALM-1222-TR2G is a wideband RF amplifier and is one of the most commonly used types of amplifier in the global market. Its main application fields include mobile communication, aerospace and defense, Radar, Automotive, Amateur Radio, broadband communication, and other applications.

ALM-1222-TR2G amplifier is a two-stage power amplifier with a stand-by switch. It is designed using Metel-Semiconductor technology. The amplifier can be tuned from 100 to 1000 MHz and can be used in mobile communication, radar, and aerospace applications. It can provide high levels of power up to 100 W with low noise and high linearity.

The working principle of ALM-1222-TR2G amplifier is based on the Hay circuit, which is a very efficient two-stage amplifier with a very high gain. The first stage of the amplifier consists of transistors connected in a Darlington configuration, while the second stage is composed of three common-emitter transistors connected in a chain. The signal passes through the input stage and then is amplified in the second stage.

The amplifier has several voltage-controlled components, such as inductors, capacitors, resistors, diodes, and other electronic components, which are used to control the gain, frequency response, linearity, and input and output impedance of the amplifier. These components also provide temperature and voltage stability to ensure reliable operation of the amplifier.

The amplifier uses two types of feedback circuits for output power control, namely voltage feedback and current feedback. The voltage feedback is used to control output power, while the current feedback is used for linearization. These feedback circuits are tuned for optimum performance to ensure that the amplifier works in the desired frequency range. In order to reduce the effects of thermal runaway, the amplifier has a bias circuit, which is designed to reduce the operating temperatures of the components.

ALM-1222-TR2G has several features that make it suitable for a wide range of applications. It has a wide frequency response, and can support a wide range of power levels. It has a high power efficiency, and is capable of delivering high linearity and low noise. Additionally, it is designed to have low power consumption, which makes it an excellent choice for mobile communication, Aerospace and defense, Airborne, Amateur Radio, and other such applications.
