Working Principle

The HMC388LP4TR utilizes a distributed power amplifier topology. This topology is based on combining multiple amplifiers to create one larger high-power system. Each individual amplifier is small and highly efficient, and they are connected together in a serpentine pattern. This topology has the important benefit of reducing the effect of intermodulation distortion, which can degrade the linearity of the RF output. In addition, this topology also reduces the power consumption and increases the operating temperature range of the device.

The HMC388LP4TR also incorporates active matching and auto-level control, which helps to improve its linearity and reduce its distortion levels. Auto-level control provides feedback from the power detectors to adjust the gain of the amplifier, ensuring that the RF output is within the optimal range. Active matching is used to provide impedance matching, which improves the efficiency and RF output power of the device. In addition, active matching compensates for any temperature or frequency changes that affect the system.
