The LE9551DMQC is an integrated, multiband envelope tracking power amplifier designed for LTE FDD-LTE, TD-SCDMA, and other 4G broadband wireless applications. It offers a high efficiency and linearity, making it an ideal choice for use in advanced base station equipment.

The LE9551DMQC is a high efficiency multi-band amplifier which is capable of operating at a variety of power levels and frequencies. It is designed to maximize the performance and efficiency of mobile base stations while meeting the stringent requirements of FDD-LTE and TD-SCDMA systems. It offers excellent linearity, low thermal drift, and immunity from high current switching noise.

At the core of the LE9551DMQC is a fully integrated power amplifier with envelope tracking capabilities which allow for greater efficiency and ultimately, lower energy consumption. The envelope tracking feature of the amplifier is a unique control mechanism used for modulating the power output of the amplifier by tracking the power waves of the input signal. This helps to reduce the peak-to-average power ratio, resulting in a more efficient amplifier with improved performance.

The LE9551DMQC is also equipped with an Adaptive Linearization feature, which enables the amplifier to adapt to changes in the load and provide linear performance over a wide range of conditions. This feature makes the LE9551DMQC suitable for use in dense, multi-cell environments.

In addition, the LE9551DMQC is designed with a built-in digital signal processor (DSP) to handle digital baseband signal processing. The DSP allows the amplifier to be used in a variety of applications such as sidelink communications, wireless backhaul and wireless access points. The built-in DSP is designed to offer better performance than analogous analog-based signal processing.

The LE9551DMQC is a versatile and reliable amplifier with a wide variety of features making it an optimal choice for use in a range of telecommunications applications. It offers improved efficiency, enhanced signal-to-noise ratio, and improved linearity for demanding applications. It is well-suited for use in mobile base station applications, where its excellent power efficiency, robust performance, and small form factor make it an ideal choice.
