Working Principle:

The ADL5321ARKZ-R7 is a high-speed power amplifier designed for optimum gain and linearity performance. Its key features include a wide bandwidth (0.1-3.5 GHz) and wide power range (13 to 30 dBm), enabling it to provide fast switching and excellent linearization performance. It operates by using an externally controlled class-AB architecture, which helps reduce the DC power consumption of the system and improve overall system efficiency. Additionally, it has a high-linearity design which allows the amplifier to be used in applications where high linearity is required.

The amplifier utilizes on-die capacitors and resistors to achieve the desired gain and bandwidth. The amplifier is designed to provide excellent linearity, distortion, and noise figure for a wide frequency range with small size, low power consumption, and high-reliability. It can be used in base station, multiple-input multiple-output (MIMO) and beamforming applications.
