Working Principle

The HSMP-381Z-TR1G amplifier module is powered by a voltage supply and has a control logic module with an external switch to control the power state of the amplifier. In addition, there is a gain control pin that enables external adjustment of the amplifier\'s gain. The amplifier module consists of two stages – the power amplifier and the low noise amplifier (LNA). The power amplifier consists of eight transistors connected in parallel configuration. These transistors are responsible for increasing the power of the input signals. The LNA is connected to the power amplifier and is responsible for amplifying the input signals further with very low noise. This combination of the power amplifier and LNA ensures higher levels of power and minimal noise figures.

The module has a low impedance output designed to drive 50Ω and 75Ω load devices such as antennas and other radio frequency components. It provides high output power while maintaining low power consumption. The power amplifier stage features an AD8484 power module to provide high power gain with low noise, making this ideal for high power applications.
