RF Amplifiers

The HMC311ST89ETR is a low noise amplifier (LNA) module designed to provide high linearity at very low distortion levels. It is particularly well-suited for applications in the Broadband Wireless, Cellular, Navigation, and TV/CATV markets. This amplifier offers some very useful features, such as a gain of 26 dB and 50 dB of noise figure, low distortion, low power consumption, and broad frequency bandwidths of 45 MHz to 1.4 GHz.

Application Field

The HMC311ST89ETR is ideal for applications where high linearity, low distortion, and low noise figure are essential. These include radio and television broadcasting, cell phones, navigation, and other wireless communications systems. The amplifier can also be used in other areas such as radar and instrumentation.

Working Principle

The HMC311ST89ETR LNA module is based on a three-stage design. The first stage is an active circuit which provides linear amplification of the input signal. The second stage consists of a differential circuit which filters out unwanted noise and distortion. The third stage is an active circuit that further amplifies the signal and provides the desired gain.This amplifier combines two state-of-the-art amplifier technologies in order to achieve its high performance. The first is a standard complementary balanced Gilbert Cell topology, and the second is a high-power FET topology. The combination of these two technologies results in an amplifier that is able to deliver high, gain, low noise figure, and low distortion while using low power.The main feature of the HMC311ST89ETR is its ability to operate over a wide bandwidth, from 45 MHz to 1.4 GHz. This is achieved by the amplifier\'s ability to adapt its gain characteristics to any given signal type. This feature gives it a very wide range of applications, from broadcast and cellular transmitters, to radios, navigation systems, and other wireless communications.

Conclusion

The HMC311ST89ETR is a low noise amplifier designed for high linearity and low distortion, and is ideal for applications in the broadcast, cellular, navigation, and other wireless communications markets. It is equipped with two state-of-the-art amplifier technologies, a standard complementary balanced Gilbert Cell topology, and a high-power FET topology, allowing it to provide excellent gain, low noise figure, and low distortion while using low power. Additionally, it has a wide operating bandwidth, from 45 MHz to 1.4 GHz, giving it a versatile range of applications.
