RF amplifiers refer to electronic circuits that amplify wireless signals in radio frequency range, mainly to improve the power and signal level of the signal. UPC2709T-E3-A is a multi-function amplifier with wide application fields. It is designed for DC-1.2GHz frequency range with wide voltage range, low cost, high reliability and miniaturization.

Application field

UPC2709T-E3-A has a total of two application fields. The first is that it can be used as a low noise amplifier (LNA) or power amplifier (PA) in the system of mobile and wireless communication. This includes functions such as mobile base stations, 802.11 wireless, RFID readers and satellite communication systems. The other is that it can be used in any other system that requires low noise or power amplification. Besides, the large voltage range of UPC2709T-E3-A makes it suitable for various characteristics, such as multimode operation, linear performance, and broadband performance.

Working principle

UPC2709T-E3-A uses an anolog circuit structure, containing a driver stage and a final power amplifying stage. The driver stage utilizes the common source (CS) structure while the final power amplifying stage utilizes the common collector structure (common emitter for power amplifiers). The bias voltage can be customized according to user needs, and the static control parameters are set in the production stage. In addition, UPC2709T-E3-A is equipped with additional functions such as thermal protection, port DC shutdown, current limiter, over voltage protection, power shutdown, etc.

Under normal operation, the RF signal enters the common source stage for signal amplification, and then the amplified signal is passed to the common collector (or common emitter) stage for power amplification. All stages are digitally controlled by integrated circuits, providing a wide range of configurable settings, including frequency, gain, IQ, etc. Furthermore, the integrated circuits allow efficient optimization of the dynamic and static characteristics of the entire amplifier. With its wide application field and excellent performance, UPC2709T-E3-A is a cost-effective solution for the RF amplifier.
