RF Amplifiers are essential components in many radio frequencies (RF) applications. The MHVIC2115R5 RF Amplifier is a finished device that incorporates a fully matched BiCMOS Feedback Amplifier with a variable gain control (VGC) chip. It has become the preferred choice for many applications where performance and reliability are paramount.

Application Field of MHVIC2115R5

The MHVIC2115R5 RF Amplifier offers a highly reliable and robust solution for broadcasting, broadcast monitoring, radio receivers, cellular base station, and other RF systems. With its low noise figure, high gain and linearity, it provides excellent signal throughput and robust performance in both terrestrial broadcast and wireless systems. Its wide impedance matching range (1.5Ω to 50Ω) also makes it an ideal choice for a variety of specialized applications in telecommunication and broadcast. The integrated Feedback Amplifier features several critical characteristics such as a low noise figure, high gain, excellent linearity, and low distortion, making it the perfect choice for broadcasting and other wireless applications.

Working Principle of MHVIC2115R5

The MHVIC2115R5 is designed to work as a single piece of equipment, incorporating both the amplifier and the variable gain control (VGC) chip. The amplifier is built around an operational transconductance amplifier (OTA) circuit, which serves as the signal input stage. The OTA then drives another stage known as the intermediate frequency (IF) amplifier. It is from the IF amplifier that the output signal is derived, using the VGC chip to adjust the gain of the amplifier.

The VGC chip is necessary for the amplifier to work correctly, as it adjusts the gain of the amplifier in response to any changes in input signals. It also provides additional functions such as temperature compensation, which prevents the amplifier gain from changing due to changes in ambient temperature. This feature helps maintain the stability and flatness of the output signal.

The MHVIC2115R5 is a fully integrated amplifier that requires no external components. It contains all the necessary components to operate, including the IF amplifier, the VGC chip, and the OTA stage. This integrated approach ensures a reliable and robust performance in all operating conditions, making the MHVIC2115R5 the ideal choice for demanding applications.
