Low Noise Amplifiers – A Must-Have in Communication Devices

Low noise amplifiers (LNA) are electronic components used in amplifying weak signals received by different antenna. They are mostly integrated in front-end modules of satellites, personal communication service (PCS) handsets, and other electronic devices. They are currently functional between the ranges of direct current (DC) to alternate currents higher than 60 GHz. Silicon (Si), gallium arsenide (GaAs), and silicon germanium (SiGe) are materials commonly used in building these components. End-use industries dependent on LNAs include telecommunications, data communications, consumer electronics, and medical.

Impact on Industries

Long-term evolution (LTE) technology has ensured longevity of 4G and 5G networks. Tower Semiconductor Ltd., a U.S. company, has developed the BiCMOS technology, which integrates LNAs to receive signals from 4G and 5G networks. This can also influence sales of antennas and antenna switches, which cater to LTE. This is expected to guarantee sales of consumer electronic devices in the long run.

Phased array feeds are radio cameras that can provide aerial mapping of the sky. With the help of LNAs, it can amplify the signals to offer high speed Internet services. The Square Kilometer Array (SKA) is such a project that has harnessed the power of LNAs to provide Internet to residents of Australia, New Zealand, and South Africa over a one square kilometer area. 

Market Overview

According to a report available on Radiant Insights, Inc., the low noise amplifier market is expected to expand from 2017 to 2022 (forecast period) due to future development of smart cities. In addition, upgradation of infrastructure to provide Wi-Fi in public spots is anticipated to augment market demand in the forthcoming years. Proliferation of smartphones and navigation systems can also play a major role in affecting market dynamics.

Prominent market players include MACOM Technology Solutions Holdings, Inc.; Broadcom Ltd; Microsemi Corporation; and NXP Semiconductors N.V.
