TRF2436IRTBR

RF Front End (LNA + PA)

The TRF2436IRTBR is a two-in-one front end that integrates a Low Noise Amplifier (LNA) and a Power Amplifier (PA) for Wireless Local Area Networks (WLANs) and WiMAX applications. This RF front end has been designed to meet the most stringent requirements of modern communication systems. It offers significant improvements in noise figure and linearity performance over existing discrete amplifier implementations. Moreover, it is highly resistant to high temperature operation, making it suitable for a wide range of applications. This article will discuss the application fields and working principles of the TRF2436IRTBR.

Application Field

The TRF2436IRTBR can be applied in a wide range of Wireless Local Area Network (WLAN) and WiMAX applications. It is ideal for point-to-point and point-to-multipoint wireless systems. It can also be used in multi-band systems requiring linearity and low noise to deliver higher speed data communication. Moreover, its broad dynamic range and wide range of temperatures make it suitable for a variety of military and medical applications.

Working Principle

The TRF2436IRTBR consists of an LNA integrated with a linear Power Amplifier (PA). The LNA section is designed using CMOS 0.18um technology, and is fabricated using the 4-metal layer process. It achieves low noise figure while maintaining high linearity performance. The LNA is followed by a PA which provides high output power even with low input power. The TRF2436IRTBR is controlled by an embedded switch control logic, which regulates the start-up of the LNA and PA sections. The TRF2436IRTBR is further accompanied by a series of protection circuits that protect the device from over current, over temperature and over voltage conditions.
